Regulatory Approvals

FCC Statement

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.

This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and receiver.

Connect the equipment into an outlet on a circuit different from that to which the receiver

is connected.

Consult the dealer or an experienced radio/TV technician for help.

To assure continued compliance, any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. (Example - use only shielded interface cables when connecting to computer or peripheral devices).

FCC Radiation Exposure Statement

This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

(1) This device may not cause harmful interference, and

(2) This device must accept any interference received, including interference that may cause undesired operation.

The antennas used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons.

Channel

The Wireless Channel sets the radio frequency used for communication.

•Access Points use a fixed Channel. You can select the Channel used. This allows you to choose a Channel which provides the least interference and best performance. In the USA and Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent Access Points use different Channels to reduce interference.

• In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an Access Point. If more than one Access Point can be used, the one with the strongest signal is used. (This can only happen within an ESS.)

• If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the same Channel. However, most Wireless stations will still scan all Channels to see if there is an existing "Ad-hoc" group they can join.

Introduction

This chapter describes the features of the NETGEAR 54 Mbps Mobile Broadband Router MBR814. The MBR814 router is a combination of a wireless broadband modem, router, 4-port switch, and firewall which enables your entire network to safely share an Internet connection.

Note: If you are unfamiliar with networking and routing, refer to Appendix B, “Network

and Routing Basics” to become more familiar with the terms and procedures used in this

manual.

About the Router

The 54 Mbps Mobile Broadband Router MBR814 provides continuous, high-speed 10/100 Ethernet access between your Ethernet devices. The MBR814 router enables your entire network to share an Internet connection through the wireless broadband modem that otherwise is used by a single computer. With minimum setup, you can install and use the router within minutes.

The MBR814 router provides multiple Web content filtering options, plus e-mail browsing activity, reporting, and instant alerts. Parents and network administrators can establish restricted access policies based on time of day, Web site addresses, and address keywords. They can also share high-speed Internet access for up to 253 personal computers. The included firewall and Network Address Translation (NAT) features protect you from hackers.

Key Features

The MBR814 router provides the following features:

• A powerful, true firewall.

• 802.11g standards-based wireless networking.

• Content filtering.

• Auto Sensing and Auto Uplink™ LAN Ethernet connections.

Introduction 2-1

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

• Easy, Web-based setup for installation and management.

• Extensive Internet protocol support.

• A card slot with PC card for wireless broadband access.

These features are discussed below.

802.11 Standards-based Wireless Networking

The MBR814 router includes an 802.11 g-compliant wireless access point, providing continuous, high-speed 10/100 Mbps access between your wireless and Ethernet devices. The access point provides:

• 802.11 g Standards-based wireless networking at up to 100 Mbps.

• Works with both 802.11g and 802.11b wireless devices.

• 64-bit and 128-bit WEP encryption security.

• WEP keys can be entered manually or generated by passphrase.

• Support for the Wi-FI Protected Pre-Shared Key (WPA-PSK) encryption and 802.1x authentication.

• Wireless access can be restricted by MAC address.

A Powerful, True Firewall

Unlike simple Internet sharing NAT routers, the MBR814 is a true firewall, using stateful packet inspection to defend against hacker attacks. Its firewall features include:

• Denial of Service (DoS) protection Automatically detects and thwarts Denial of Service (DoS) attacks such as Ping of Death, SYN Flood, LAND Attack and IP Spoofing.

• Blocks unwanted traffic from the Internet to your LAN.

• Blocks access from your LAN to Internet locations or services that you specify as off-limits.

• Logs security incidents The MBR814 will log security events such as blocked incoming traffic, port scans, attacks, and administrator logins. You can configure the router to email the log to you at specified intervals. You can also configure the router to send immediate alert messages to your email address or email pager whenever a significant event occurs.

Reference Manual for the Broadband Mobile Router MBR814

Content Filtering

With its content filtering feature, the MBR814 prevents objectionable content from reaching your computers. The router allows you to control access to Internet content by screening for keywords within Web addresses. You can configure the router to log and report attempts to access objectionable Internet sites.

Auto Sensing and Auto Uplink™ LAN Ethernet Connections

With its internal 4-port 10/100 switch, the MBR814 can connect to either a 10 Mbps standard Ethernet network or a 100 Mbps Fast Ethernet network. The local LAN ports are autosensing and capable of full-duplex or half-duplex operation.

The router incorporates Auto Uplink sense whether the Ethernet cable plugged into the port should have a ‘normal’ connection such as to a computer or an ‘uplink’ connection such as to a switch or hub. That port will then configure itself to the correct configuration. This feature also eliminates the need to worry about crossover cables, as Auto Uplink will accommodate either type of cable to make the right connection.

technology. Each local Ethernet port will automatically

Protocol Support

The MBR814 supports Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing Information Protocol (RIP). Appendix B, “Network and Routing Basics” provides further information on TCP/IP.

• The Ability to Enable or Disable IP Address Sharing by NAT The MBR814 allows several networked PCs to share an Internet account using only a single IP address, which may be statically or dynamically assigned by your Internet service provider (ISP). This technique, known as Network Address Translation (NAT), allows the use of an inexpensive single-user ISP account. This feature can also be turned off completely while using the MBR814 if you want to manage the IP address scheme yourself.

• Automatic Configuration of Attached PCs by DHCP The MBR814 dynamically assigns network configuration information, including IP, router, and domain name server (DNS) addresses, to attached PCs on the LAN using the Dynamic Host Configuration Protocol (DHCP). This feature greatly simplifies configuration of PCs on your local network.

• DNS Proxy When DHCP is enabled and no DNS addresses are specified, the router provides its own address as a DNS server to the attached PCs. The router obtains actual DNS addresses from the ISP during connection setup and forwards DNS requests from the LAN.

Reference Manual for the Broadband Mobile Router MBR814

• Classical IP (RFC 1577) Some Internet service providers, in Europe for example, use Classical IP in their ADSL services. In such cases, the router is able to use the Classical IP address from the ISP.

• Dynamic DNS Dynamic DNS services allow remote users to find your network using a domain name when your IP address is not permanently assigned. The router contains a client that can connect to many popular Dynamic DNS services to register your dynamic IP address.

• Universal Plug and Play (UPnP) UPnP is a networking architecture that provides compatibility between networking technologies. UPnP compliant routers provide broadband users at home and small businesses with a seamless way to participate in online games, videoconferencing and other peer-to-peer services.

Easy Installation and Management

You can install, configure, and operate the MBR814 within minutes after connecting it to the network. The following features simplify installation and management tasks:

• Browser-based management Browser-based configuration allows you to easily configure your router from almost any type of personal computer, such as Windows, Macintosh, or Linux. A user-friendly Setup Wizard is provided and online help documentation is built into the browser-based Web Management Interface.

• Remote management The router allows you to log in to the Web management interface from a remote location via the Internet. For security, you can limit remote management access to a specified remote IP address or range of addresses, and you can choose a nonstandard port number.

• Diagnostic functions The router incorporates built-in diagnostic functions such as Ping, DNS lookup, and remote reboot. These functions allow you to test Internet connectivity and reboot the router. You can use these diagnostic functions directly from the MBR814 when you are connected on the LAN or when you are connected over the Internet via the remote management function.

• Visual monitoring The router’s front panel LEDs provide an easy way to monitor its status and activity.

• Flash erasable programmable read-only memory (EPROM) for firmware upgrades.

Information” on page 3-3.

3-6 Connecting the Router to the Internet

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

Testing Your Internet Connection

After completing the Internet connection configuration, your can test your Internet connection. Log in to the router, then, from the Basic Settings link in the Setup menu, click the Test button. If the NETGEAR Web site does not appear within one minute, refer to Chapter 8,

“Troubleshooting”.

Your router is now configured to provide Internet access for your network. Your router automatically connects to the Internet when one of your computers requires access. It is not necessary to run a dialer or login application such as Dial-Up Networking or Enternet to connect, log in, or disconnect. These functions are performed by the router as needed.

To access the Internet from any computer connected to your router, launch a browser such as Microsoft Internet Explorer or Netscape Navigator. You should see the router’s Internet LED blink, indicating communication to the ISP. The browser should begin to display a Web page.

The following chapters describe how to configure the Advanced features of your router, and how to troubleshoot problems that may occur.

Manually Configuring Your Internet Connection

You can configure your router using the Basic Setup menu shown to the right, or you can allow the Setup Wizard to determine your configuration as described in the previous section.

1. Set the WAN IP Address:

• Select “Get Dynamically from ISP” if your

ISP uses DHCP to assign your IP address. Your ISP will automatically assign these addresses.

• Select “Use Static IP Address” if your ISP has

assigned you a permanent, fixed (static) IP address. Enter the IP address that your ISP assigned. Also enter the IP Subnet Mask and the Gateway IP Address. The gateway is the ISP’s router to which your router will connect.

Connecting the Router to the Internet 3-7

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

2. Specify the Domain Name Server (DNS) Address:

• Select “Get Dynamically from ISP” if your ISP uses DHCP to assign your IP address.

Your ISP will automatically assign this address.

• If you know that your ISP does not automatically transmit DNS addresses to the router

during login, select “Use these DNS servers” and enter the IP address of your ISP’s Primary DNS Server. If a Secondary DNS Server address is available, enter it also.

A DNS server is a host on the Internet that translates Internet names (such as www.netgear.com) to numeric IP addresses. Typically your ISP transfers the IP address of one or two DNS servers to your router during login. If the ISP does not transfer an address, you must obtain it from the ISP and enter it manually here.

3. You should only disable NAT if you are sure you do not require it. NAT automatically assigns private IP addresses (192.168.0.x) to LAN connected devices. When NAT is disabled, only standard routing is performed by this router.

Classical routing lets you directly manage the IP addresses the MBR814 uses. Classical routing should be selected only by experienced users.

Note: Disabling NAT will reboot the router and reset all the MBR814 configuration settings to the factory default. Disable NAT only if you plan to install the MBR814 in a setting where you will be manually administering the IP address space on the LAN side of the router

4. Router MAC Address: This section determines the Ethernet MAC address that will be used by the router on the Internet port. Some ISPs will register the Ethernet MAC address of the network interface card in your computer when your account is first opened. They will then only accept traffic from the MAC address of that computer. This feature allows your router to masquerade as that computer by “cloning” its MAC address.

To change the MAC address, select “Use this Computer’s MAC address”. The router will then capture and use the MAC address of the computer that you are now using. You must be using the one computer that is allowed by the ISP. Alternatively, select “Use this MAC address” and enter it.

5. Click Apply to save your settings.

6. Click the Test button to test your Internet connection.

If the NETGEAR Web site does not appear within one minute, refer to Chapter 8,

“Troubleshooting”.

Chapter 4

Wireless Configuration

This chapter describes how to configure the wireless features of your 54 Mbps Mobile Broadband Router MBR814.

Considerations for a Wireless Network

In planning your wireless network, you should consider the level of security required. You should also select the physical placement of your router in order to maximize the network speed. For further information, refer to Appendix D, “Wireless Networking Basics”.

Observe Performance, Placement, and Range Guidelines

The operating distance or range of your wireless connection can vary significantly based on the physical placement of the wireless firewall. The latency, data throughput performance, and notebook power consumption also vary depending on your configuration choices.

Note: Failure to follow these guidelines can result in significant performance degradation or inability to wirelessly connect to the router. For complete range/ performance specifications, please see Appendix A, “Technical Specifications”.

For best results, place your firewall:

• Near the center of the area in which your computers will operate

• In an elevated location such as a high shelf where the wirelessly connected computers have line-of-sight access (even if through walls)

• Away from sources of interference, such as computers, microwaves, and cordless phones

• With the Antenna tight and in the upright position

• Away from large metal surfaces

Security Options

Range: Up to 300 Feet

The time it takes to establish a wireless connection can vary depending on both your security settings and placement. WEP connections can take slightly longer to establish. Also, WEP encryption can consume more battery power on a notebook computer.

Implement Appropriate Wireless Security

Note: Indoors, computers can connect over 802.11g wireless networks at a maximum range of up to 300 feet. Such distances can allow for others outside of your immediate area to access your network.

Unlike wired network data, your wireless data transmissions can extend beyond your walls and can be received by anyone with a compatible adapter. For this reason, use the security features of your wireless equipment. The MBR814 router provides highly effective security features which are covered in detail in this chapter. Deploy the security features appropriate to your needs.

MBR814

Figure 4-1: MBR814 wireless data security options

There are several ways you can enhance the security of your wireless network:

• Restrict Access Based on MAC Address. You can allow only trusted PCs to connect so that unknown PCs cannot wirelessly connect to the MBR814. Restricting access by MAC address adds an obstacle against unwanted access to your network, but the data broadcast over the wireless link is fully exposed.

• Turn Off the Broadcast of the Wireless Network Name SSID. If you disable broadcast of the SSID, only devices that have the correct SSID can connect. This nullifies wireless network ‘discovery’ feature of some products, such as Windows XP, but the data is still exposed.

4-2 Wireless Configuration

Reference Manual for the Mobile Broadband Router MBR814

• WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP Shared Key authentication and WEP data encryption will block all but the most determined eavesdropper.

• WPA-PSK. Wi-Fi Protected Access (WPA) data encryption provides data security. The very strong authentication along with dynamic per frame re-keying of WPA make it virtually impossible to compromise. Because this is a new standard, wireless device driver and software availability may be limited.

Understanding Wireless Settings

To configure the Wireless interface of your router, click the Wireless link in the main menu of the browser interface. The Wireless Settings menu will appear, as shown below:

Wireless Configuration 4-3

Reference Manual for the Mobile Broadband Router MBR814

Figure 4-2: Wireless Settings menu

The following parameters are in the Wireless Settings menu:

• Wireless Network.

— Name (SSID). The Service Set ID, also known as the wireless network name. Enter a

value of up to 32 alphanumeric characters. The same Name (SSID) must be assigned to all wireless devices in your network. The default SSID is NETGEAR, but NETGEAR strongly recommends that you change your network Name to a different value.

4-4 Wireless Configuration

Reference Manual for the Mobile Broadband Router MBR814

Note: This value is case sensitive. For example, Wireless is not the same as wireless.

— Region. The region can not be changed by users

— Mode. The default is "g & b", which allows both "g" and "b" wireless stations to access

this device. “g only” allows only 802.11g wireless stations to be used. “b only” allows

802.11b wireless stations; 802.11g wireless stations can still be used if they can operate in

802.11b mode.

• Wireless Access Point.

— Enable Wireless Access Point. This field lets you turn off or turn on the wireless access

point built in to the router. The wireless icon on the front of the router will also display the current status of the Wireless Access Point to let you know if it is disabled or enabled. The wireless access point must be enabled to allow wireless stations to access the Internet.

— Allow Broadcast of Name (SSID). If enabled, the SSID is broadcast to all Wireless

Stations. Stations which have no SSID (or a "null" value) can then adopt the correct SSID for connections to this Access Point.

— Wireless Isolation. If enabled, Wireless Stations will not be able to communicate with

each other or with Stations on the wired network. This feature should normally be disabled.

• Wireless Station Access List.

— By default, any wireless computer that is configured with the correct wireless network

name or SSID will be allowed access to your wireless network. For increased security, you can restrict access to the wireless network to only specific computers based on their MAC addresses. Click Setup Access List to display the Wireless Station Access List menu.

How to Set Up and Test Basic Wireless Connectivity

Follow the instructions below to set up and test basic wireless connectivity. Once you have established basic wireless connectivity, you can enable security settings appropriate to your needs.

1. Log in to the MBR814 firewall at its default LAN address of http://192.168.0.1 with its default user name of admin and default password of password, or using whatever LAN address and password you have set up.

2. Click the Wireless Settings link in the main menu of the MBR814 firewall.

3. Choose a suitable descriptive name for the wireless network name (SSID). In the SSID box, enter a value of up to 32 alphanumeric characters. The default SSID is Wireless.

Note: The SSID of any wireless access adapters must match the SSID you configure in the 54 Mbps Mobile Broadband Router MBR814. If they do not match, you will not get a wireless connection to the MBR814.

Wireless Configuration 4-7

Reference Manual for the Mobile Broadband Router MBR814

6. For initial configuration and test, leave the Wireless Card Access List set to allow everyone access by making sure that “Turn Access Control On” is not selected in the Wireless Station Access List. In addition, leave the Encryption Strength set to “Disabled.”

7. Click Apply to save your changes.

Note: If you are configuring the firewall from a wireless computer and you change the firewall’s SSID, channel, or security settings, you will lose your wireless connection when you click Apply. You must then change the wireless settings of your computer to match the firewall’s new settings.

8. Configure and test your computers for wireless connectivity.

Program the wireless adapter of your computers to have the same SSID and channel that you configured in the router. Check that they have a wireless link and are able to obtain an IP address by DHCP from the firewall.

Once your computers have basic wireless connectivity to the firewall, you can configure the advanced wireless security functions of the firewall.

How to Restricting Wireless Access to Your Network

By default, any wireless PC that is configured with the correct SSID will be allowed access to your wireless network. For increased security, the 54 Mbps Mobile Broadband Router MBR814 provides several ways to restrict wireless access to your network:

• Turn off wireless connectivity completely

• Restrict access based on the Wireless Network Name (SSID)

• Restrict access based on the Wireless Card Access List

These options are discussed below.

4-8 Wireless Configuration

Reference Manual for the Mobile Broadband Router MBR814

Figure 4-3: Wireless Access Point settings

Restricting Access to Your Network by Turning Off Wireless Connectivity

You can completely turn off the wireless portion of the MBR814. For example, if your notebook computer is used to wirelessly connect to your router and you take a business trip, you can turn off the wireless portion of the router while you are traveling. Other members of your household who use computers connected to the router via Ethernet cables will still be able to use the router.

Restricting Wireless Access Based on the Wireless Network Name (SSID)

The MBR814 can restrict wireless access to your network by not broadcasting the wireless network name (SSID). However, by default, this feature is turned off. If you turn this feature on, wireless devices will not ‘see’ your MBR814. You must configure your wireless devices to match the wireless network name (SSID) you configure in the MBR814 router.

Restricting Wireless Access Based on the Wireless Station Access List

This list determines which wireless hardware devices will be allowed to connect to the firewall.

To restrict access based on MAC addresses, follow these steps:

2. From the Wireless Settings menu, Wireless Station Access List section, click the Setup Access List button to display the list, shown below:

Wireless Configuration 4-9

Reference Manual for the Mobile Broadband Router MBR814

Figure 4-4: Wireless Access menu

3. Select the Turn Access Control On check box to enable restricting wireless computers by their MAC addresses.

4. If the wireless station is currently connected to the network, you can select it from the Available Wireless Stations list. Click Add to add the station to the Trusted Wireless Stations list.

5. If the wireless station is not currently connected, you can enter its address manually. Enter the MAC address of the authorized computer. The MAC address is usually printed on the wireless card, or it may appear in the router’s DHCP table. The MAC address will be 12 hexadecimal digits.

Click Add to add your entry. You can add several stations to the list, but the entries will be discarded if you do not click Apply.

Note: You can copy and paste the MAC addresses from the router’s Attached Devices menu into the MAC Address box of this menu. To do this, configure each wireless computer to obtain a wireless link to the router. The computer should then appear in the Attached Devices menu.

4-10 Wireless Configuration

Reference Manual for the Mobile Broadband Router MBR814

Note: If you are configuring the router from a wireless computer whose MAC address is not in the Trusted Wireless Stations list, and you select Trusted Wireless Stations only, you will lose your wireless connection when you click Apply. You must then access the router from a wired computer to make any further changes.

6. Make sure the Turn Access Control On check box is selected, then click Apply.

Now, only devices on this list will be allowed to wirelessly connect to the MBR814. This prevents unauthorized access to your network.

Choosing WEP Authentication and Security Encryption Methods

Figure 4-5. Security Encryption section

Restricting wireless access prevents intruders from connecting to your network. However, the wireless data transmissions are still vulnerable to snooping. Using the WEP data encryption settings described below will prevent a determined intruder from eavesdropping on your wireless data communications. Also, if you are using the Internet for such activities as purchases or banking, those Internet sites use another level of highly secure encryption called SSL. You can tell if a web site is using SSL because the web address begins with HTTPS rather than HTTP.

Authentication Type Selection

The MBR814 lets you select the following wireless authentication schemes.

• Automatic

Wireless Configuration 4-11

Reference Manual for the Mobile Broadband Router MBR814

• Open System

• Shared key

Note: The authentication scheme is separate from the data encryption. You can choose an authentication scheme which requires a shared key but still leave the data transmissions unencrypted. If you require strong security, use both the Shared Key and WEP encryption settings.

Set your wireless adapter according to the authentication scheme you choose for the MBR814 router. Please refer to “Authentication and WEP Data Encryption” on page D-2 for a full explanation of each of these options, as defined by the IEEE 802.11g wireless communication standard.

Encryption Choices

Please refer to “Overview of WEP Parameters” on page D-5 for a full explanation of each of the following choices, as defined by the IEEE 802.11g wireless communication standard. Choose the encryption strength from the drop-down list:

Chapter 5

Protecting Your Network

This chapter describes how to use the basic firewall features of the 54Mbps Mobile Broadband Router MBR814 to protect your network.

Protecting Access to Your 54Mbps Mobile Broadband Router MBR814

For security reasons, the router has its own user name and password. Also, after a period of inactivity for a set length of time, the administrator login will automatically disconnect. When prompted, enter admin for the router User Name and password for the router Password. You can use procedures below to change the router's password and the amount of time for the administrator’s login timeout.

Note: The user name and password are not the same as any user name or password your may use to log in to your Internet connection.

NETGEAR recommends that you change this password to a more secure password. The ideal password should contain no dictionary words from any language, and should be a mixture of both upper and lower case letters, numbers, and symbols. Your password can be up to 30 characters.

How to Change the Built-In Password

1. Log in to the router at its default LAN address of http://192.168.0.1 with its default User Name of admin, default password of password, or using whatever Password and LAN address you have chosen for the router.

Figure 5-1: Log in to the router

2. From the Main Menu of the browser interface, under the Maintenance heading, select Set Password to bring up the menu shown in Figure 5-2.

Protecting Your Network 5-1

3. To change the password, first enter the old password, and then enter the new password twice.

4. Click Apply to save your changes.

Note: After changing the password, you will be required to log in again to continue the configuration. If you have backed up the router settings previously, you should do a new backup so that the saved settings file includes the new password.

Changing the Administrator Login Timeout

For security, the administrator's login to the router configuration will timeout after a period of inactivity. To change the login timeout period:

1. In the Set Password menu, type a number in ‘Administrator login times out’ field. The suggested default value is 5 minutes.

2. Click Apply to save your changes or click Cancel to keep the current period.

Configuring Basic Firewall Services

Basic firewall services you can configure include access blocking and scheduling of firewall security. These topics are presented below.

Reference Manual for the Broadband Mobile Router MBR814

Blocking Keywords, Sites, and Services

The router provides a variety of options for blocking Internet based content and communications services. With its content filtering feature, the MBR814 router prevents objectionable content from reaching your PCs. The router allows you to control access to Internet content by screening for keywords within Web addresses. Key content filtering options include:

• Keyword blocking of HTTP traffic.

• Outbound Service Blocking limits access from your LAN to Internet locations or services that you specify as off-limits.

• Denial of Service (DoS) protection. Automatically detects and thwarts Denial of Service (DoS) attacks such as Ping of Death, SYN Flood, LAND Attack and IP Spoofing.

• Blocking unwanted traffic from the Internet to your LAN.

The section below explains how to configure your

router to perform these functions.

How to Block Keywords and Sites

The MBR814 router allows you to restrict access to Internet content based on functions such as Web addresses and Web address keywords.

2. Select the Block Sites link of the Security menu.

Protecting Your Network 5-3

202-10005-05, June 2005

3. To enable keyword blocking, select one of the following:

• Per Schedule—to turn on keyword blocking according to the settings on the Schedule

page.

• Always—to turn on keyword blocking all of the time, independent of the Schedule page.

4. Enter a keyword or domain in the Keyword box, click Add Keyword, then click Apply.

Some examples of Keyword application follow:

• If the keyword “XXX” is specified, the URL <http://www.badstuff.com/xxx.html> is

blocked.

• If the keyword “.com” is specified, only Web sites with other domain suffixes (such as

.edu or .gov) can be viewed.

• Enter the keyword “.” to block all Internet browsing access.

Up to 32 entries are supported in the Keyword list.

5. To delete a keyword or domain, select it from the list, click Delete Keyword, then click Apply.

6. To specify a trusted user, enter that computer’s IP address in the Trusted IP Address box and click Apply.

5-4 Protecting Your Network

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

You can specify one trusted user, which is a computer that will be exempt from blocking and logging. Since the trusted user will be identified by an IP address, you should configure that computer with a fixed IP address.

7. Click Apply to save your settings.

Firewall Rules

Firewall rules are used to block or allow specific traffic passing through from one side of the router to the other. Inbound rules (WAN to LAN) restrict access by outsiders to private resources, selectively allowing only specific outside users to access specific resources. Outbound rules (LAN to WAN) determine what outside resources local users can have access to.

A firewall has two default rules, one for inbound traffic and one for outbound. The default rules of the MBR814 are:

• Inbound: Block all access from outside except responses to requests from the LAN side.

• Outbound: Allow all access from the LAN side to the outside.

You can define additional rules that will specify exceptions to the default rules. By adding custom rules, you can block or allow access based on the service or application, source or destination IP addresses, and time of day. You can also choose to log traffic that matches or does not match the rule you have defined.

You can change the order of precedence of rules so that the rule that applies most often will take effect first. See “Order of Precedence for Rules” on page 5-11 for more details.

To access the rules configuration of the MBR814, click the Firewall Rules link on the main menu, then click Add for either an Outbound or Inbound Service.

• To edit an existing rule, select its button on the left side of the table and click Edit.

• To delete an existing rule, select its button on the left side of the table and click Delete.

• To move an existing rule to a different position in the table, select its button on the left side

of the table and click Move. At the script prompt, enter the number of the desired new position and click OK.

Inbound Rules (Port Forwarding)

Because the MBR814 uses Network Address Translation (NAT), your network presents only one IP address to the Internet, and outside users cannot directly address any of your local computers. However, by defining an inbound rule you can make a local server (for example, a Web server or game server) visible and available to the Internet. The rule tells the router to direct inbound traffic for a particular service to one local server based on the destination port number. This is also known as port forwarding.

Note: Some residential broadband ISP accounts do not allow you to run any server processes (such as a Web or FTP server) from your location. Your ISP may periodically check for servers and may suspend your account if it discovers any active services at your location. If you are unsure, refer to the Acceptable Use Policy of your ISP.

Remember that allowing inbound services opens holes in your firewall. Only enable those ports that are necessary for your network. Following are two application examples of inbound rules:

5-6 Protecting Your Network

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

Inbound Rule Example: A Local Public Web Server

If you host a public Web server on your local network, you can define a rule to allow inbound Web (HTTP) requests from any outside IP address to the IP address of your Web server at any time of day. This rule is shown in Figure 5-5:

Figure 5-5: Rule example: A Local Public Web Server

The parameters are:

•Service From this list, select the application or service to be allowed or blocked. The list already displays many common services, but you are not limited to these choices. Use the Services menu to add any additional services or applications that do not already appear.

• Action Choose how you want this type of traffic to be handled. You can block or allow always, or you can choose to block or allow according to the schedule you have defined in the Schedule menu.

• Send to LAN Server Enter the IP address of the computer or server on your LAN which will receive the inbound traffic covered by this rule.

• WAN Users These settings determine which packets are covered by the rule, based on their source (WAN) IP address. Select the desired option:

Protecting Your Network 5-7

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

– Any — all IP addresses are covered by this rule.

– Address range — if this option is selected, you must enter the Start and Finish fields.

– Single address — enter the required address in the Start field.

•Log You can select whether the traffic will be logged. The choices are:

– Never — no log entries will be made for this service.

– Always — any traffic for this service type will be logged.

– Match — traffic of this type which matches the parameters and action will be logged.

– Not match — traffic of this type which does not match the parameters and action will be

logged.

Inbound Rule Example: Allowing Videoconferencing

If you want to allow incoming videoconferencing to be initiated from a restricted range of outside IP addresses, such as from a branch office, you can create an inbound rule. In the example shown in Figure 5-6, CU-SeeMe connections are allowed only from a specified range of external IP addresses. In this case, we have also specified logging of any incoming CU-SeeMe requests that do not match the allowed parameters.

Figure 5-6: Rule example: Videoconference from Restricted Addresses

5-8 Protecting Your Network

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

Considerations for Inbound Rules

• If your external IP address is assigned dynamically by your ISP, the IP address may change periodically as the DHCP lease expires. Consider using the Dynamic DNS feature in the Advanced menu so that external users can always find your network.

• If the IP address of the local server computer is assigned by DHCP, it may change when the computer is rebooted. To avoid this, use the Reserved IP address feature in the LAN IP menu to keep the computer’s IP address constant.

• Local computers must access the local server using the computer’s local LAN address (192.168.0.11 in the example in Figure 5-6 above). Attempts by local computers to access the server using the external WAN IP address will fail.

Outbound Rules (Service Blocking)

The MBR814 allows you to block the use of certain Internet services by computers on your network. This is called service blocking or port filtering. You can define an outbound rule to block Internet access from a local computer based on:

• IP address of the local computer (source address)

• IP address of the Internet site being contacted (destination address)

•Time of day

• Type of service being requested (service port number)

Following is an application example of outbound rules:

Outbound Rule Example: Blocking Instant Messenger

If you want to block Instant Messenger usage by employees during working hours, you can create an outbound rule to block that application from any internal IP address to any external address according to the schedule that you have created in the Schedule menu. You can also have the router log any attempt to use Instant Messenger during that blocked period.

Order of Precedence for Rules

As you define new rules, they are added to the tables in the Rules menu, as shown in Figure 5-8:

Figure 5-8: Rules table with examples

Protecting Your Network 5-11

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

For any traffic attempting to pass through the firewall, the packet information is subjected to the rules in the order shown in the Rules Table, beginning at the top and proceeding to the default rules at the bottom. In some cases, the order of precedence of two or more rules may be important in determining the disposition of a packet. The Move button allows you to relocate a defined rule to a new position in the table.

Services

Services are functions performed by server computers at the request of client computers. For example, Web servers serve Web pages, time servers serve time and date information, and game hosts serve data about other players’ moves. When a computer on the Internet sends a request for service to a server computer, the requested service is identified by a service or port number. This number appears as the destination port number in the transmitted IP packets. For example, a packet that is sent with destination port number 80 is an HTTP (Web server) request.

The service numbers for many common protocols are defined by the Internet Engineering Task Force (IETF) and published in RFC1700, “Assigned Numbers.” Service numbers for other applications are typically chosen from the range 1024 to 65535 by the authors of the application.

Although the MBR814 already holds a list of many service port numbers, you are not limited to these choices. Use the procedure below to create your own service definitions.

How to Define Services

Enabling Remote Management

Using the Remote Management page, you can allow a user or users on the Internet to configure, upgrade and check the status of your 54Mbps Mobile Broadband Router MBR814.

Note: Be sure to change the router's default password to a very secure password. The ideal password should contain no dictionary words from any language, and should be a mixture of letters (both upper and lower case), numbers, and symbols. Your password can be up to 30 characters.

Configuring Remote Management

1. Log in to the router at its default LAN address of http://192.168.0.1 with its default User Name

of admin, default password of password, or using whatever User Name, Password and LAN address you have chosen for the router.

2. From the Advanced section of the main menu, select the Remote Management link.

3. Select the Turn Remote Management On check box.

4. Specify what external addresses will be allowed to access the router’s remote management.

For security, restrict access to as few external IP addresses as practical:

• To allow access from any IP address on the Internet, select Everyone.

• To allow access from a range of IP addresses on the Internet, select IP address range.

Enter a beginning and ending IP address to define the allowed range.

• To allow access from a single IP address on the Internet, select Only this Computer.

Enter the IP address that will be allowed access.

5. Specify the Port Number that will be used for accessing the management interface.

Web browser access normally uses the standard HTTP service port 80. For greater security, you can change the remote management Web interface to a custom port by entering that number in the box provided. Choose a number between 1024 and 65535, but do not use the number of any common service port. The default is 8080, which is a common alternate for HTTP.

Chapter 7

Advanced Configuration

This chapter describes how to configure the advanced features of your 54Mbps Mobile Broadband Router MBR814.

Configuring Advanced Security

The 54Mbps Mobile Broadband Router MBR814 provides a variety of advanced features, such as:

• Setting up a Demilitarized Zone (DMZ) Server

• Connecting Automatically, as Required

• Disabling Port Scan and DOS Protection

• Responding to a Ping on the Internet WAN Port

•MTU Size

• Flexibility on configuring your LAN TCP/IP settings

• Using the Router as a DHCP Server

• Configuring Dynamic DNS

• Configuring Static Routes

These features are discussed below.

Setting Up A Default DMZ Server

The Default DMZ Server feature is helpful when using some online games and videoconferencing applications that are incompatible with NAT. The router is programmed to recognize some of these applications and to work properly with them, but there are other applications that may not function well. In some cases, one local computer can run the application properly if that computer’s IP address is entered as the Default DMZ Server.

Advanced Configuration 7-1

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

Note: For security reasons, you should avoid using the Default DMZ Server feature. When a computer is designated as the Default DMZ Server, it loses much of the protection of the firewall, and is exposed to many exploits from the Internet. If compromised, the computer can be used to attack your network.

Incoming traffic from the Internet is normally discarded by the router unless the traffic is a response to one of your local computers or a service that you have configured in the Ports menu. Instead of discarding this traffic, you can have it forwarded to one computer on your network. This computer is called the Default DMZ Server.

How to Configure a Default DMZ Server

To assign a computer or server to be a Default DMZ server, follow these steps:

2. From the Main Menu, under Advanced, click the WAN Setup link to view the page shown in

Figure 7-1:

Figure 7-1: WAN Setup Page

3. Select the Default DMZ Server check box.

4. Type the IP address for that server.

5. Click Apply to save your changes.

7-2 Advanced Configuration

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

Connect Automatically, as Required

Normally, this option should be enabled, so that an Internet connection will be made automatically, whenever Internet-bound traffic is detected. If this causes high connection costs, you can disable this setting.

If disabled, you must connect manually, using the sub-screen accessed from the "Connection Status" button on the Status screen.

If you have an "Always on" connection, this setting has no effect.

Disable Port Scan and DOS Protection

The Firewall protects your LAN against Port Scans and Denial of Service (DOS) attacks. This should be disabled only in special circumstances.

Respond to Ping on Internet WAN Port

If you want the router to respond to a 'ping' from the Internet, select the ‘Respond to Ping on Internet WAN Port’ check box. This should only be used as a diagnostic tool, since it allows your router to be discovered. Do not select this box unless you have a specific reason to do so.

MTU Size

The normal MTU (Maximum Transmit Unit) value for most Ethernet networks is 1500 Bytes, or 1492 Bytes for PPPoE connections. For some ISPs you may need to reduce the MTU. But this is rarely required, and should not be done unless you are sure it is necessary for your ISP connection.

Configuring LAN IP Settings

The LAN IP Setup menu allows configuration of LAN IP services such as DHCP and RIP. These features can be found under the Advanced heading in the Main Menu of the browser interface.

The router is shipped preconfigured to use private IP addresses on the LAN side, and to act as a DHCP server. The router’s default LAN IP configuration is:

• LAN IP addresses—192.168.0.1

• Subnet mask—255.255.255.0

These addresses are part of the Internet Engineering Task Force (IETF)-designated private address range for use in private networks, and should be suitable in most applications. If your network has a requirement to use a different IP addressing scheme, you can make those changes in this menu.

Advanced Configuration 7-3

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

Figure 7-2: LAN IP Setup Menu

The LAN TCP/IP Setup parameters are:

• IP Address This is the LAN IP address of the router.

• IP Subnet Mask This is the LAN Subnet Mask of the router. Combined with the IP address, the IP Subnet Mask allows a device to know which other addresses are local to it, and which must be reached through a gateway or router.

• RIP Direction RIP (Router Information Protocol) allows a router to exchange routing information with other routers. The RIP Direction selection controls how the Router sends and receives RIP packets. Both is the default.

— When set to Both or Out Only, the router will broadcast its routing table periodically.

— When set to Both or In Only, it will incorporate the RIP information that it receives.

— When set to None, it will not send any RIP packets and will ignore any RIP packets

received.

• RIP Version This controls the format and the broadcasting method of the RIP packets that the router sends. It recognizes both formats when receiving. By default, this is set for RIP-1.

7-4 Advanced Configuration

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

— RIP-1 is universally supported. RIP-1 is probably adequate for most networks, unless you

have an unusual network setup.

— RIP-2 carries more information. Both RIP-2B and RIP-2M send the routing data in RIP-2

format.

— RIP-2B uses subnet broadcasting.

— RIP-2M uses multicasting.

Note: If you change the LAN IP address of the router while connected through the browser, you will be disconnected. You must then open a new connection to the new IP address and log in again.

DHCP

By default, the router will function as a DHCP (Dynamic Host Configuration Protocol) server, allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to the router's LAN. The assigned default gateway address is the LAN address of the router. IP addresses will be assigned to the attached PCs from a pool of addresses specified in this menu. Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN.

For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. See “IP

Configuration by DHCP”on page B-9 for an explanation of DHCP and information about how to

assign IP addresses for your network.

Use Router as DHCP server

If another device on your network will be the DHCP server, or if you will manually configure the network settings of all of your computers, clear the ‘Use router as DHCP server’ check box. Otherwise, leave it selected.

Specify the pool of IP addresses to be assigned by setting the Starting IP Address and Ending IP Address. These addresses should be part of the same IP address subnet as the router’s LAN IP address. Using the default addressing scheme, you should define a range between 192.168.0.2 and

192.168.0.254, although you may want to save part of the range for devices with fixed addresses.

The router will deliver the following parameters to any LAN device that requests DHCP:

• An IP Address from the range you have defined

• Subnet Mask

• Gateway IP Address is the router’s LAN IP address

Advanced Configuration 7-5

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

• Primary DNS Server, if you entered a Primary DNS address in the Basic Settings menu; otherwise, the router’s LAN IP address

• Secondary DNS Server, if you entered a Secondary DNS address in the Basic Settings menu

• WINS Server, short for Windows Internet Naming Service Server, determines the IP address associated with a particular Windows computer. A WINS server records and reports a list of names and IP address of Windows PCs on its local network. If you connect to a remote network that contains a WINS server, enter the server’s IP address here. This allows your PCs to browse the network using the Network Neighborhood feature of Windows.

Reserved IP addresses

When you specify a reserved IP address for a computer on the LAN, that computer will always receive the same IP address each time it access the router’s DHCP server. Reserved IP addresses should be assigned to servers that require permanent IP settings.

To reserve an IP address:

1. Click the Add button.

2. In the IP Address box, type the IP address to assign to the computer or server. Choose an IP address from the router’s LAN subnet, such as 192.168.0.x.

3. Type the MAC Address of the computer or server. Tip: If the computer is already present on your network, you can copy its MAC address from the Attached Devices menu and paste it here.

4. Click Apply to enter the reserved address into the table.

Note: The reserved address will not be assigned until the next time the computer contacts the router's DHCP server. Reboot the computer or access its IP configuration and force a DHCP release and renew.

To edit or delete a reserved address entry:

1. Click the button next to the reserved address you want to edit or delete.

2. Click Edit or Delete.

How to Configure LAN TCP/IP Settings

1. Log in to the router at its default LAN address of http://192.168.0.1 with its default User Name of admin, default password of password, or using whatever User Name, Password and LAN address you have chosen for the router.

2. From the Main Menu, under Advanced, click the LAN IP Setup link to view the menu, shown in Figure 7-3:

Figure 7-3: LAN IP Setup Menu

3. Enter the TCP/IP, DHCP, or Reserved IP parameters.

4. Click Apply to save your changes.

Configuring Dynamic DNS

If your network has a permanently assigned IP address, you can register a domain name and have that name linked with your IP address by public Domain Name Servers (DNS). However, if your Internet account uses a dynamically assigned IP address, you will not know in advance what your IP address will be, and the address can change frequently. In this case, you can use a commercial dynamic DNS service that will allow you to register your domain to their IP address, and will forward traffic directed at your domain to your frequently-changing IP address.

The router contains a client that can connect to a dynamic DNS service provider. To use this feature, you must select a service provider and obtain an account with them. After you have configured your account information in the router, whenever your ISP-assigned IP address changes, your router will automatically contact your dynamic DNS service provider, log in to your account, and register your new IP address.

Advanced Configuration 7-7

3. Access the Web site of one of the dynamic DNS service providers whose names appear in the ‘Service Provider’ box, and register for an account. For example, for dyndns.org, go to www.dyndns.org.

4. Select the “Use a dynamic DNS service” check box.

5. Select the name of your dynamic DNS Service Provider.

6. Type the Host Name that your dynamic DNS service provider gave you. The dynamic DNS service provider may call this the domain name. If your URL is myName.dyndns.org, then your Host Name is “myName.”

7. Type the User Name for your dynamic DNS account.

8. Type the Password (or key) for your dynamic DNS account.

9. If your dynamic DNS provider allows the use of wildcards in resolving your URL, you can select the Use wildcards check box to activate this feature. For example, the wildcard feature will cause *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org

7-8 Advanced Configuration

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

10. Click Apply to save your configuration.

Note: If your ISP assigns a private WAN IP address such as 192.168.x.x or 10.x.x.x, the

dynamic DNS service will not work because private addresses will not be routed on the Internet.

Using Static Routes

Static Routes provide additional routing information to your router. Under normal circumstances, the router has adequate routing information after it has been configured for Internet access, and you do not need to configure additional static routes. You must configure static routes only for unusual cases such as multiple routers or multiple IP subnets located on your network.

Static Route Example

As an example of when a static route is needed, consider the following case:

• Your primary Internet access is through a cable modem to an ISP.

• You have an ISDN router on your home network for connecting to the company where

you are employed. This router’s address on your LAN is 192.168.0.100.

• Your company’s network is 134.177.0.0.

When you first configured your router, two implicit static routes were created. A default route was created with your ISP as the router, and a second static route was created to your local network for all 192.168.0.x addresses. With this configuration, if you attempt to access a device on the

134.177.0.0 network, your router will forward your request to the ISP. The ISP forwards your

request to the company where you are employed, and the request will likely be denied by the company’s firewall.

In this case you must define a static route, telling your router that 134.177.0.0 should be accessed through the ISDN router at 192.168.0.100. The static route would look like Figure 7-6.

In this example:

• The Destination IP Address and IP Subnet Mask fields specify that this static route applies to all 134.177.x.x addresses.

• The Router IP Address fields specifies that all traffic for these addresses should be forwarded to the ISDN router at 192.168.0.100.

Advanced Configuration 7-9

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

• A Metric value of 1 will work since the ISDN router is on the LAN. This represents the number of routers between your network and the destination. This is a direct connection so it is set to 1.

• Private is selected only as a precautionary security measure in case RIP is activated.

How to Configure Static Routes

2. From the Main Menu of the browser interface, under Advanced, click Static Routes to view the Static Routes menu, shown in Figure 7-5.

Figure 7-5: Static Routes Table

3. To add or edit a Static Route:

a. Click the Edit button to open the Edit Menu, shown in Figure 7-6.

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

b. Type a route name for this static route in the Route Name box under the table.

This is for identification purpose only.

c. Select Private if you want to limit access to the LAN only.

The static route will not be reported in RIP.

d. Select Active to make this route effective.

e. Type the Destination IP Address of the final destination.

f. Type the IP Subnet Mask for this destination.

If the destination is a single host, type 255.255.255.255.

g. Type the Gateway IP Address, which must be a router on the same LAN segment as the

router.

h. Type a number between 1 and 15 as the Metric value.

This represents the number of routers between your network and the destination. Usually, a setting of 2 or 3 works, but if this is a direct connection, set it to 1.

4. Click Apply to have the static route entered into the table.

Universal Plug and Play (UPnP)

Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access the network and connect to other devices as needed. UPnP devices can automatically discover the services from other registered UPnP devices on the network.

1. Click UPnP on the main menu to invoke the UPnP menu:

Figure 7-7: Universal Plug and Play menu

Advanced Configuration 7-11

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

2. Fill out the UPnP screen:

• Tur n UP nP O n: UPnP can be enabled or disabled for automatic device configuration. The

default setting for UPnP is enabled. If disabled, the Router will not allow any device to automatically control the resources, such as port forwarding (mapping), of the Router.

• Advertisement Period: The Advertisement Period is how often the Router will advertise

(broadcast) its UPnP information. This value can range from 1 to 1440 minutes. The default period is for 30 minutes. Shorter durations will ensure that control points have current device status at the expense of additional network traffic. Longer durations may compromise the freshness of the device status but can significantly reduce network traffic.

• Advertisement Time To Live: The time to live for the advertisement is measured in hops

(steps) for each UPnP packet sent. A hop is the number of steps allowed to propagate for each UPnP advertisement before it disappears. The number of hops can range from 1 to

255. The default value for the advertisement time to live is 4 hops, which should be fine for most home networks. If you notice that some devices are not being updated or reached correctly, then it may be necessary to increase this value a little.

• UPnP Portmap Table: The UPnP Portmap Table displays the IP address of each UPnP

device that is currently accessing the Router and which ports (Internal and External) that device has opened. The UPnP Portmap Table also displays what type of port is opened and if that port is still active for each IP address.

3. To save, cancel or refresh the table:

a. Click Apply to save the new settings to the Router.

b. Click Cancel to disregard any unsaved changes.

c. Click Refresh to update the portmap table and to show the active ports that are currently

opened by UPnP devices.

Troubleshooting

This chapter gives information about troubleshooting your 54Mbps Mobile Broadband Router MBR814. After each problem description, instructions are provided to help you diagnose and solve the problem. For the common problems listed, go to the section indicated.

• Is the router on?

• Have I connected the router correctly?

Go to “Basic Functioning” on page 8-1.

• I can’t access the router’s configuration with my browser.

Go to “Troubleshooting the Web Configuration Interface” on page 8-3.

• I’ve configured the router but I can’t access the Internet.

Go to “Troubleshooting the ISP Connection” on page 8-4.

• I can’t remember the router’s configuration password.

• I want to clear the configuration and start over again.

Go to “Restoring the Default Configuration and Password” on page 8-7.

Basic Functioning

After you turn on power to the router, the following sequence of events should occur:

1. When power is first applied, verify that the Power LED is on (see “The Router’s Front Panel”

on page 2-5 for an illustration and explanation of the LEDs).

2. Verify that the Test LED lights within a few seconds, indicating that the self-test procedure is running.

3. After approximately 10 seconds, verify that:

a. The Test LED is not lit.

b. The LAN port LEDs are lit for any local ports that are connected.

c. The WAN port LED is lit.

Troubleshooting 8-1

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

If a port’s LED is lit, a link has been established to the connected device. If a LAN port is connected to a 100 Mbps device, verify that the port’s LED is green. If the port is 10 Mbps, the LED will be amber.

If any of these conditions does not occur, refer to the appropriate following section.

Power LED Not On

If the Power and other LEDs are off when your router is turned on:

• Make sure that the power cord is properly connected to your router and that the power supply adapter is properly connected to a functioning power outlet.

• Check that you are using the 12 V DC power adapter supplied by NETGEAR for this product.

If the error persists, you have a hardware problem and should contact technical support.

Test LED Never Turns On or Test LED Stays On

When the router is turned on, the Test LED turns on for about 10 seconds and then turns off. If the Test LED does not turn on, or if it stays on, there is a fault within the router.

If you experience problems with the Test LED:

• Cycle the power to see if the router recovers and the LED blinks for the correct amount of time.

If all LEDs including the Test LED are still on one minute after power up:

• Cycle the power to see if the router recovers.

• Clear the router’s configuration to factory defaults. This will set the router’s IP address to

192.168.0.1. This procedure is explained in “Using the Reset button” on page 8-7.

If the error persists, you might have a hardware problem and should contact technical support.

LAN or WAN Port LEDs Not On

If either the LAN LEDs or WAN LED do not light when the Ethernet connection is made, check the following:

• Make sure that the Ethernet cable connections are secure at the router and at the hub or workstation.

• Make sure that power is turned on to the connected hub or workstation.

• Be sure the wireless broadband PC card is inserted properly.

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

Troubleshooting the Web Configuration Interface

If you are unable to access the router’s Web Configuration interface from a computer on your local network, check the following:

• If you are using an Ethernet-connected computer, check the Ethernet connection between the computer and the router as described in the previous section.

• Make sure your computer’s IP address is on the same subnet as the router. If you are using the recommended addressing scheme, your computer’s address should be in the range of

192.168.0.2 to 192.168.0.254. Refer to “Verifying TCP/IP Properties” on page C-6 or

“Verifying TCP/IP Properties for Macintosh Computers” on page C-17 to find your

computer’s IP address. Follow the instructions in Appendix C to configure your computer.

Note: If your computer’s IP address is shown as 169.254.x.x: Recent versions of Windows and MacOS will generate and assign an IP address if the computer cannot reach a DHCP server. These auto-generated addresses are in the range of 169.254.x.x. If your IP address is in this range, check the connection from the computer to the router and reboot your computer.

• If your router’s IP address was changed and you do not know the current IP address, clear the router’s configuration to factory defaults. This will set the router’s IP address to 192.168.0.1. This procedure is explained in “Using the Reset button” on page 8-7.

• Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet Explorer, click Refresh to be sure the Java applet is loaded.

• Try quitting the browser and launching it again.

• Make sure you are using the correct login information. The factory default login name is admin and the password is password. Make sure that CAPS LOCK is off when entering this information.

If the router does not save changes you have made in the Web Configuration Interface, check the following:

• When entering configuration settings, be sure to click the APPLY button before moving to another menu or tab, or your changes are lost.

• Click the Refresh or Reload button in the Web browser. The changes may have occurred, but the Web browser may be caching the old configuration.

Troubleshooting the ISP Connection

If your router is unable to access the Internet, you should check the ADSL connection, then the WAN TCP/IP connection.

ADSL link

If your router is unable to access the Internet, you should first determine whether you have an ADSL link with the service provider. The state of this connection is indicated with the WAN LED.

Internet LED Green or Blinking Green

If your Internet LED is green or blinking green, then you have a good broadband connection. You can be confident that the service provider has connected your line correctly and that your wiring is correct.

Internet LED Off

If the Internet LED is off, disconnect the power to the router. Ensure the wireless broadband PC card is inserted properly and re-connect the power to the router.

If the problem persists, the wireless coverage in your area may be poor or the PC card may be defective.

Obtaining an Internet IP Address

If your router is unable to access the internet, and your Internet LED is green or blinking green, you should determine whether the router is able to obtain a Internet IP address from the ISP. Unless you have been assigned a static IP address, your router must request an IP address from the ISP. You can determine whether the request was successful using the browser interface.

To check the WAN IP address from the browser interface:

1. Launch your browser and select an external site such as www.netgear.com.

2. Access the Main Menu of the router’s configuration at http://192.168.0.1.

3. Under the Maintenance heading check that an IP address is shown for the WAN Port. If 0.0.0.0 is shown, your router has not obtained an IP address from your ISP.

If your router is unable to obtain an IP address from the ISP, the problem may be one of the following:

8-4 Troubleshooting

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

• Your ISP may check for your computer's host name. Assign the computer Host Name of your ISP account to the router in the browser-based Setup Wizard.

• You have poor wireless coverage.

• Your ISP only allows one Ethernet MAC address to connect to Internet, and may check for your computer’s MAC address. In this case:

Inform your ISP that you have bought a new network device, and ask them to use the router’s MAC address.

Configure your router to spoof your computer’s MAC address. This can be done in the Basic Settings menu. Refer to “Manually Configuring Your Internet Connection” on page 3-7.

Troubleshooting Internet Browsing

If your router can obtain an IP address but your computer is unable to load any Web pages from the Internet:

• Your computer may not recognize any DNS server addresses.

A DNS server is a host on the Internet that translates Internet names (such as www addresses) to numeric IP addresses. Typically your ISP will provide the addresses of one or two DNS servers for your use. If you entered a DNS address during the router’s configuration, reboot your computer and verify the DNS address as described in “Verifying TCP/IP Properties” on

page C-6. Alternatively, you can configure your computer manually with DNS addresses, as

explained in your operating system documentation.

• Your computer may not have the router configured as its TCP/IP router.

If your computer obtains its information from the router by DHCP, reboot the computer and verify the router address as described in “Verifying TCP/IP Properties” on page C-6.

Troubleshooting a TCP/IP Network Using the Ping Utility

Most TCP/IP terminal devices and routers contain a ping utility that sends an echo request packet to the designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP network is made very easy by using the ping utility in your computer.

Reference Manual for the Broadband Mobile Router MBR814

Testing the LAN Path to Your Router

You can ping the router from your computer to verify that the LAN path to your router is set up correctly.

To ping the router from a PC running Windows 95 or later:

1. From the Windows toolbar, click the Start button and select Run.

2. In the field provided, type Ping followed by the IP address of the router, as in this example:

ping 192.168.0.1

3. Click OK.

You should see a message like this one:

Pinging <IP address> with 32 bytes of data

If the path is working, you see this message:

Reply from < IP address >: bytes=32 time=NN ms TTL=xxx

If the path is not working, you see this message:

Request timed out

If the path is not functioning correctly, you could have one of the following problems:

• Wrong physical connections

— Make sure the LAN port LED is on. If the LED is off, follow the instructions in “LAN

or WAN Port LEDs Not On” on page 8-2.

— Check that the corresponding Link LEDs are on for your network interface card and

for the hub ports (if any) that are connected to your workstation and router.

• Wrong network configuration

— Verify that the Ethernet card driver software and TCP/IP software are both installed

and configured on your PC or workstation.

— Verify that the IP address for your router and your workstation are correct and that the

addresses are on the same subnet.

Testing the Path from Your Computer to a Remote Device

After verifying that the LAN path works correctly, test the path from your PC to a remote device. From the Windows run menu, type:

PING -n 10 <IP address>

8-6 Troubleshooting

202-10005-05, June 2005

Reference Manual for the Broadband Mobile Router MBR814

where <IP address> is the IP address of a remote device such as your ISP’s DNS server.

If the path is functioning correctly, replies as in the previous section are displayed. If you do not receive replies:

— Check that your PC has the IP address of your router listed as the default router. If the IP

configuration of your PC is assigned by DHCP, this information will not be visible in your PC’s Network Control Panel. Verify that the IP address of the router is listed as the default router as described in “Verifying TCP/IP Properties” on page C-6.

— Check to see that the network address of your PC (the portion of the IP address specified

by the netmask) is different from the network address of the remote device.

— Check that your wireless broadband PC card is installed properly.

— If your ISP assigned a host name to your PC, enter that host name as the Account Name in

the Basic Settings menu.

— Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Many

broadband ISPs restrict access by only allowing traffic from the MAC address of your broadband modem, but some ISPs additionally restrict access to the MAC address of a single PC connected to that modem. If this is the case, you must configure your router to “clone” or “spoof” the MAC address from the authorized PC. Refer to “Manually

Configuring Your Internet Connection” on page 3-7.

Restoring the Default Configuration and Password

This section explains how to restore the factory default configuration settings, changing the router’s administration password to password and the IP address to 192.168.0.1. You can erase the current configuration and restore factory defaults in two ways:

• Use the Erase function of the Web Configuration Manager (see “Backing Up, Restoring, or

Erasing Your Settings” on page 6-1).

• Use the Default Reset button on the rear panel of the router. Use this method for cases when the administration password or IP address is not known.

Using the Reset button

To restore the factory default configuration settings without knowing the administration password or IP address, you must use the Default Reset button on the rear panel of the router.

1. Press and hold the Default Reset button until the Test LED turns on (about 10 seconds).

2. Release the Default Reset button and wait for the router to reboot.

Problems with Date and Time

The E-mail menu in the Content Filtering section displays the current date and time of day. The MBR814 router uses the Network Time Protocol (NTP) to obtain the current time from one of several Network Time Servers on the Internet. Each entry in the log is stamped with the date and time of day. Problems with the date and time function can include:

• Date shown is January 1, 2000 Cause: The router has not yet successfully reached a Network Time Server. Check that your Internet access settings are configured correctly. If you have just completed configuring the router, wait at least five minutes and check the date and time again.

• Time is off by one hour Cause: The router does not automatically sense Daylight Savings Time. In the E-mail menu, check or uncheck the box marked “Adjust for Daylight Savings Time”.
