Introduction

Congratulations on your purchase of the NETGEAR® RangeMax Wireless Router WPN824. The WPN824 router provides connection for multiple computers to the Internet through an external broadband access device (such as a cable modem or DSL modem) that is normally intended for use by a single computer. This chapter describes the features of the NETGEAR RangeMax Wireless Router WPN824.

Key Features

Note: This manual provides information on the complete features as of the date of publication. Earlier versions of this product may not have all the features presented in this manual. Go to http://kbserver.netgear.com/products/WPN824.asp where you will find product firmware updates for your WPN824.

The RangeMax Wireless Router WPN824 with 4-port switch connects your local area network (LAN) to the Internet through an external access device such as a cable modem or DSL modem.

The WPN824 router provides you with multiple Web content filtering options, plus browsing activity reporting and instant alerts via e-mail.

202-10072-01, March 2005

Reference Manual for the RangeMax Wireless Router WPN824

Built in 4-port 10/100 Mbps Switch.

Ethernet connection to a wide area network (WAN) device, such as a cable modem or DSL modem.

Extensive Protocol Support.

Login capability.

Front panel LEDs for easy monitoring of status and activity.

Flash memory for firmware upgrades.

RangeMax™ Multi-In, Multi-Out (MIMO) Technology

Netgear’s RangeMax Multi-In, Multi-Out (MIMO) technology provides ten times more coverage than standard 802.11g alone by eliminating “dead spots” in your area of coverage where you use your wireless computers. Your whole house or office suite now becomes a “hot spot” without requiring any range extenders, repeaters, or external antennas. RangeMax maintains your high speed throughout your home, not just when you are close to your router.

RangeMax is an advanced Smart MIMO (Multi-In, Multi-Out) technology that uses seven internal antennas. RangeMax constantly surveys your home environment for physical barriers and interference and adjusts the wireless signal to compensate for these performance blockers.

For example, if you carry your laptop from the family room to the bedroom, RangeMax automatically senses the change and selects from over 100 possible antenna configurations to deliver you the fastest, clearest connection so that everyone can enjoy consistently high-speed connections, everywhere in your house with no drop-outs and no dead spots.

RangeMax is also 100% compatible with your existing 802.11b/g products (i.e., 802.11b, 802.11g, Centrino, and SuperG™ wireless clients) and boosts their range and speed by up to 50%.

802.11g Wireless Networking

The WPN824 router includes an 802.11g wireless access point, providing continuous, high-speed 108 Mbps access between your wireless and Ethernet devices. The access point provides:

802.11g wireless networking at up to 108 Mbps.

802.11g wireless networking, with the ability to operate in 802.11g-only, 802.11b-only, or 802.11g and b modes, providing backwards compatibility with 802.11b devices or dedicating the wireless network to the higher bandwidth 802.11g devices.

64-bit and 128-bit WEP encryption security.

WEP keys can be generated manually or by passphrase.

Introduction

202-10072-01, March 2005

Reference Manual for the RangeMax Wireless Router WPN824

WPA-PSK support. Support for Wi-Fi Protected Access (WPA) data encryption which provides strong data encryption and authentication based on a pre-shared key.

Wireless access can be restricted by MAC address.

Wireless network name broadcast can be turned off so that only devices that have the network name (SSID) can connect.

A Powerful, True Firewall with Content Filtering

Unlike simple Internet sharing NAT routers, the WPN824 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 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 WPN824 will log security events such as blocked incoming traffic, port scans, attacks, and administrator logins. You can configure the router to E-mail the log to you at specified intervals. You can also configure the router to send immediate alert messages to your E-mail address or E-mail pager whenever a significant event occurs.

The WPN824 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.

Security

The WPN824 router is equipped with several features designed to maintain security, as described in this section.

Computers Hidden by NAT

NAT opens a temporary path to the Internet for requests originating from the local network. Requests originating from outside the LAN are discarded, preventing users outside the LAN from finding and directly accessing the computers on the LAN.

Introduction

2-3

202-10072-01, March 2005

Reference Manual for the RangeMax Wireless Router WPN824

Port Forwarding with NAT

Although NAT prevents Internet locations from directly accessing the computers on the LAN, the router allows you to direct incoming traffic to specific computers based on the service port number of the incoming request, or to one designated “DMZ” host computer. You can specify forwarding of single ports or ranges of ports.

Autosensing Ethernet Connections with Auto Uplink

With its internal 4-port 10/100 switch, the WPN824 can connect to either a 10 Mbps standard Ethernet network or a 100 Mbps Fast Ethernet network. Both the LAN and WAN interfaces are autosensing and capable of full-duplex or half-duplex operation.

The router incorporates Auto UplinkTM technology. Each Ethernet port will automatically 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.

Extensive Protocol Support

The WPN824 router supports the Transmission Control Protocol/Internet Protocol

(TCP/IP) and Routing Information Protocol (RIP). For further information about TCP/IP, refer to Appendix B, “Network, Routing, Firewall, and Basics.”

IP Address Sharing by NAT

The WPN824 router allows several networked computers 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 NAT, allows the use of an inexpensive single-user ISP account.

Automatic Configuration of Attached computers by DHCP

The WPN824 router dynamically assigns network configuration information, including IP, gateway, and domain name server (DNS) addresses, to attached computers on the LAN using the Dynamic Host Configuration Protocol (DHCP). This feature greatly simplifies configuration of computers 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 computers. The router obtains actual DNS addresses from the ISP during connection setup and forwards DNS requests from the LAN.

Reference Manual for the RangeMax Wireless Router WPN824

PPP over Ethernet (PPPoE)

PPPoE is a protocol for connecting remote hosts to the Internet over a DSL connection by simulating a dial-up connection. This feature eliminates the need to run a login program such as Entersys or WinPOET on your computer.

Easy Installation and Management

You can install, configure, and operate the RangeMax Wireless Router WPN824 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.

Smart Wizard

The WPN824 router Smart Wizard automatically senses the type of Internet connection, asking you only for the information required for your type of ISP account.

Firmware Update

The WPN824 router can be updated if a newer version of firmware is available. This lets you take advantage of product enhancements for your WPN824 as soon as they become available.

Visual monitoring

The WPN824 router’s front panel LEDs provide an easy way to monitor its status and activity.

Maintenance and Support

NETGEAR offers the following features to help you maximize your use of the WPN824 router:

Flash memory for firmware upgrades.

A Road Map for ‘How to Get There From Here’

The introduction and adoption of any new technology can be a difficult process. Broadband Internet service is considered so useful that more and more people want to set up networks in their home to share a broadband connection. Wireless technology has removed one of the barriers to networking—running wires. It allows more people to try networking while at the same time exposes them to the inherent complexity of networking. General networking concepts, setup, and maintenance can be difficult to understand. In addition, wireless technology adds issues, such as range, interference, signal quality, and security to the picture.

To help overcome potential barriers to successfully using home networks, the table below identifies how to accomplish such things as connecting to a wireless network, assuring appropriate security measures are taken, browsing the Internet through your wireless connection, exchanging files with other computers and using printers in the combined wireless and wired network.

Troubleshooting Tips

Here are some tips for correcting simple problems you may have.

Be sure to restart your network in this sequence:

1) Turn off the modem, wireless router, and computer; 2) Turn on the modem, wait two minutes; 3) Turn on the wireless router and wait 1 minute; 4) Turn on the computer.

Make sure the Ethernet cables are securely plugged in.

The Internet status light on the wireless router will be lit if the Ethernet cable to the wireless router from the modem is plugged in securely and the modem and wireless router are turned on.

For each powered on computer connected to the wireless router with a securely plugged in Ethernet cable, the corresponding wireless router LAN port status light will be lit. The label on the bottom of the wireless router identifies the number of each LAN port.

Make sure the wireless settings in the computer and router match exactly.

The Wireless Network Name (SSID) and WEP settings of the router and wireless computer must match exactly.

Make sure the network settings of the computer are correct.

LAN and wirelessly connected computers must be configured to obtain an IP address automatically via DHCP. Please see Appendix C, “Preparing Your Network” or the animated tutorials on the CD for help with this.

Some cable modem ISPs require you to use the MAC address of the computer registered on the account. If so, in the Router MAC Address section of the Basic Settings menu, 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 computer that is registered with the ISP. Click Apply to save your settings. Restart the network in the correct sequence.

Check the router status lights to verify correct router operation.

If the Power light does not turn solid green within 2 minutes after turning the router on, reset the router according to the instructions in “Restoring the Default Configuration and Password” on page 7-7.

If the Wireless light does not come on, verify that the wireless feature is turned on according to the instructions in “Understanding Wireless Settings” on page 4-4.

3.Click Basic Settings on the Setup menu.

4.If your Internet connection does not require a login, click No at the top of the Basic Settings menu and fill in the settings according to the instructions below. If your Internet connection does require a login, click Yes, and skip to step 5.

a.Enter your Account Name (may also be called Host Name) and Domain Name.

These parameters may be necessary to access your ISP’s services such as mail or news servers.

b.Internet IP Address:

If your ISP has assigned you a permanent, fixed (static) IP address for your computer, select “Use static IP address”. Enter the IP address that your ISP assigned. Also enter the netmask and the Gateway IP address. The Gateway is the ISP’s router to which your router will connect.

c.Domain Name Server (DNS) 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.

Note: If you enter an address here, restart the computers on your network so that these settings take effect.

d.Router’s 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. Or, select “Use this MAC address” and type it in here.

Chapter 4

Wireless Configuration

This chapter describes how to configure the wireless features of your WPN824 router. In planning your wireless network, you should consider the level of security required. You should also select the physical placement of your firewall in order to maximize the network speed. For further information on wireless networking, 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 of wireless adapters 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 2.4 GHz cordless phones.

Away from large metal surfaces.

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 and WPA-PSK \encryption can consume more battery power on a notebook computer.

Wireless Configuration

Reference Manual for the RangeMax Wireless Router WPN824

When used on a metallic surface, MIMO units must be oriented vertically to ensure proper operation:

Figure 4-1: Vertical orientation required on metallic surfaces

Implement Appropriate Wireless Security

Note: Indoors, computers can connect over 802.11b/g wireless networks at ranges 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 be received well beyond your walls by anyone with a compatible adapter. For this reason, use the security features of your wireless equipment. The WPN824 router provides highly effective security features which are covered in detail in this chapter. Deploy the security features appropriate to your needs.

4)WPA-PSK: very strong security

Figure 4-2: WPN824 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 restrict access to only trusted computers so that unknown computers cannot wirelessly connect to the WPN824. MAC address filtering 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 the wireless network ‘discovery’ feature of some products such as Windows XP, but the data is still fully exposed to a determined snoop using specialized test equipment like wireless sniffers.

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, Pre-Shared Key (WPA-PSK) data encryption provides strong data security. WPA-PSK will block eavesdropping. Because this is a new standard, wireless device driver and software availability may be limited.

Turn Off the Wired LAN. If you disable the wireless LAN, wireless devices cannot communicate with the router at all. You might choose to turn off the wireless the LAN when you are away and the others in the household all use wired connections.

Name (SSID). The SSID is also known as the wireless network name. Enter a value of up to 32 alphanumeric characters. In a setting where there is more than one wireless network, different wireless network names provide a means for separating the traffic. Any device you want to participate in a particular wireless network will need to use this SSID for that network. The WPN824 default SSID is: NETGEAR.

Region. This field identifies the region where the WPN824 can be used. It may not be legal to operate the wireless features of the wireless router in a region other than one of those identified in this field.

Note: The region selection feature may not be available in all countries.

Channel. This field determines which operating frequency will be used. It should not be necessary to change the wireless channel unless you notice interference problems with another nearby access point. For more information on the wireless channel frequencies please refer to “Wireless Channels” on page D-7.

Mode. This field determines which data communications protocol will be used. You can select “g only,” “b only,” or “g and b.” “g only” dedicates the WPN824 to communicating with the higher bandwidth 802.11g wireless devices exclusively. “b only” dedicates the WPN824 to communicating with the higher bandwidth 802.11b wireless devices exclusively. The “g and b” mode provides backward compatibility with the slower 802.11b wireless devices while still enabling 802.11g communications.

Security Options. These options are the wireless security features you can enable. The table below identifies the various basic wireless security options. A full explanation of these standards is available in Appendix D, “Wireless Networking Basics.”

Table 4-1.

Basic Wireless Security Options

 

 

Field

Description

 

 

Automatic

No wireless security.

 

 

WEP

WEP offers the following options:

 

• Open System

 

With Open Network Authentication and 64or 128-bit WEP Data Encryption, the WPN824

 

does perform 64or 128-bit data encryption but does not perform any authentication.

 

• Shared Key

 

Shared Key authentication encrypts the SSID and data.

 

Choose the Encryption Strength (64or 128-bit data encryption). Manually enter the key

 

values or enter a word or group of printable characters in the Passphrase box. Manually

 

entered keys are case sensitive but passphrase characters are not case sensitive.

 

Note: Not all wireless adapter configuration utilities support passphrase key generation.

 

• Auto

WPA-PSK

WPA-Pre-shared Key does perform authentication, uses 128-bit data encryption and

 

dynamically changes the encryption keys making it nearly impossible to circumvent.

 

Enter a word or group of printable characters in the Password Phrase box. These characters

 

are case sensitive.

 

Note: Not all wireless adapter configuration utilities support WPA. Furthermore, client software

 

is required on the client. Windows XP and Windows 2000 with Service Pack 3 do include the

 

client software that supports WPA. Nevertheless, the wireless adapter hardware and driver

 

must also support WPA.

Information to Gather Before Changing Basic Wireless Settings

Before customizing your wireless settings, print this form and record the following information. If you are working with an existing wireless network, the person who set up or is responsible for the network will be able to provide this information. Otherwise, you will choose the settings for your wireless network. Either way, record the settings for your wireless network in the spaces below.

Wireless Network Name (SSID): ______________________________ The SSID, identifies the wireless network. You can use up to 32 alphanumeric characters. The SSID is case sensitive. The SSID in the wireless adapter card must match the SSID of the wireless router. In some configuration utilities (such as in Windows XP), the term “wireless network name” is used instead of SSID.

If WEP Authentication is Used. Circle one: Open System, Shared Key, or Auto.

Note: If you select Shared Key, the other devices in the network will not connect unless they are set to Shared Key as well and are configured with the correct key.

WEP Encryption key size. Choose one: 64-bit or 128-bit. Again, the encryption key size must be the same for the wireless adapters and the wireless router.

Data Encryption (WEP) Keys. There are two methods for creating WEP data encryption keys. Whichever method you use, record the key values in the spaces below.

Passphrase method. ______________________________ These characters are case sensitive. Enter a word or group of printable characters and click the Generate Keys button. Not all wireless devices support the passphrase method.

Manual method. These values are not case sensitive. For 64-bit WEP, enter 10 hex digits (any combination of 0-9 or a-f). For 128-bit WEP, enter 26 hex digits.

Key 1: ___________________________________

Key 2: ___________________________________

Key 3: ___________________________________

Key 4: ___________________________________

If WPA-PSK Authentication is Used.

Passphrase: ______________________________ These characters are case sensitive. Enter a word or group of printable characters. When you use WPA-PSK, the other devices in the network will not connect unless they are set to WPA-PSK as well and are configured with the correct Passphrase.

Use the procedures described in the following sections to configure the WPN824. Store this information in a safe place.

Blocking Access to Internet Sites

The WPN824 router allows you to restrict access based on Web addresses and Web address keywords. Up to 255 entries are supported in the Keyword list. The Block Sites menu is shown in Figure 5-1 below:

Figure 5-1: Block Sites menu

To enable keyword blocking, select either “Per Schedule” or “Always”, then click Apply. If you want to block by schedule, be sure that a time period is specified in the Schedule menu.

To add a keyword or domain, type it in the Keyword box, click Add Keyword, then click Apply.

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

Keyword application examples:

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

Content Filtering

202-10072-01, March 2005

Reference Manual for the RangeMax Wireless Router WPN824

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

.gov) can be viewed.

If you wish to block all Internet browsing access during a scheduled period, enter the keyword “.” and set the schedule in the Schedule menu.

To specify a Trusted User, enter that PC’s IP address in the Trusted User box and click Apply.

You may specify one Trusted User, which is a PC that will be exempt from blocking and logging. Since the Trusted User will be identified by an IP address, you should configure that PC with a fixed IP address.

Blocking Access to Internet Services

The WPN824 router allows you to block the use of certain Internet services by PCs on your network. This is called services blocking or port filtering. The Block Services menu is shown below:

Figure 5-2: Block Services menu

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 your network sends a request for service to a server computer on the Internet, 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.

To enable service blocking, select either Per Schedule or Always, then click Apply. If you want to block by schedule, be sure that a time period is specified in the Schedule menu.

Content Filtering

To specify a service for blocking, click Add. The Add Services menu will appear, as shown below:

Figure 5-3: Add Services menu

From the Service Type list, select the application or service to be allowed or blocked. The list already displays several common services, but you are not limited to these choices. To add any additional services or applications that do not already appear, select User Defined.

Configuring a User Defined Service

To define a service, first you must determine which port number or range of numbers is used by the application. 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. This information can usually be determined by contacting the publisher of the application or from user groups of newsgroups.

Enter the Starting Port and Ending Port numbers. If the application uses a single port number, enter that number in both boxes.

If you know that the application uses either TCP or UDP, select the appropriate protocol. If you are not sure, select Both.

Troubleshooting

This chapter gives information about troubleshooting your RangeMax Wireless Router WPN824. After each problem description, instructions are provided to help you diagnose and solve the problem.

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 light is on.

2.After approximately 10 seconds, verify that:

a.The power light is solid green.

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

c.The Internet port light is lit.

If a port’s light 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 light is green. If the port is 10 Mbps, the light will be amber.

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

Power Light Not On

If the Power and other lights 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 1A power adapter supplied by NETGEAR for this product.

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

Lights Never Turn Off

When the router is turned on, the lights turns on for about 10 seconds and then turn off. If all the lights stay on, there is a fault within the router.

If all lights 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 192.168.1.1. This procedure is explained in “Restoring the Default Configuration and Password” on page 7-7.

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

LAN or WAN Port Lights Not On

If either the LAN lights or Internet light 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 you are using the correct cable:

When connecting the router’s Internet port to a cable or DSL modem, use the cable that was supplied with the cable or DSL modem. This cable could be a standard straight-through Ethernet cable or an Ethernet crossover cable.

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:

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 192.168.1.2 to 192.168.1.254. Refer to “Verifying TCP/IP Properties” on page C-8 or “Verifying TCP/IP Properties for Macintosh Computers” on page C-19 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 has been changed and you don’t know the current IP address, clear the router’s configuration to factory defaults. This will set the router’s IP address to 192.168.1.1. This procedure is explained in “Restoring the Default Configuration and Password” on page 7-7.

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.

Reference Manual for the RangeMax Wireless Router WPN824

Troubleshooting the ISP Connection

If your router is unable to access the Internet, you should first determine whether the router is able to obtain a WAN 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 Web Configuration Manager.

To check the WAN IP address:

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://www.routerlogin.net.

3.Under the Maintenance heading, select Router Status

4.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, you may need to force your cable or DSL modem to recognize your new router by performing the following procedure:

1.Turn off power to the cable or DSL modem.

2.Turn off power to your router.

3.Wait five minutes and reapply power to the cable or DSL modem.

4.When the modem’s lights indicate that it has reacquired sync with the ISP, reapply power to your router.

5.Then restart your computer.

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

Your ISP may require a login program.

Ask your ISP whether they require PPP over Ethernet (PPPoE) or some other type of login.

If your ISP requires a login, you may have incorrectly set the login name and password.

Your ISP may check for your computer's host name.

Assign the computer Host Name of your ISP account as the Account Name in the Basic Settings menu.

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

Troubleshooting

202-10072-01, March 2005

Reference Manual for the RangeMax Wireless Router WPN824

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

OR

Configure your router to spoof your computer’s MAC address. This can be done in the Basic Settings menu. Refer to “How to Bypass the Configuration Assistant” on page 3-8.

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 “Install or Verify Windows Networking Components” on page C-9. Alternatively, you may 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 gateway.

If your computer obtains its information from the router by DHCP, reboot the computer and verify the gateway address as described in “Install or Verify Windows Networking Components” on page C-9.

Troubleshooting a TCP/IP Network Using a 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 or workstation.

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 running Windows 95 or later:

1.From the Windows toolbar, click on 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 192.168.1.1

3. Click on 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 Lights Not On” on page 7-2.

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 computer 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 computer to a remote device. From the Windows run menu, type:

PING -n 10 <IP address>

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 computer has the IP address of your router listed as the default gateway. If the IP configuration of your computer is assigned by DHCP, this information will not be visible in your computer’s Network Control Panel. Verify that the IP address of the router is listed as the default gateway as described in “Install or Verify Windows Networking Components” on page C-9.

7-6

Troubleshooting

202-10072-01, March 2005

Reference Manual for the RangeMax Wireless Router WPN824

Check to see that the network address of your computer (the portion of the IP address specified by the netmask) is different from the network address of the remote device.

Check that your cable or DSL modem is connected and functioning.

If your ISP assigned a host name to your computer, 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 computers. 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 computer connected to that modem. If this is the case, you must configure your router to “clone” or “spoof” the MAC address from the authorized computer. Refer to “How to Bypass the Configuration Assistant” on page 3-8.

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 192.168.1.1. You can erase the current configuration and restore factory defaults in two ways:

Use the Erase function of the router (see “Erasing the Configuration” on page 6-7).

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.

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 power light blinks on (about 10 seconds).

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

If the wireless router fails to restart or the power light continues to blink or turns solid amber, the unit may be defective. If the error persists, you might have a hardware problem and should contact technical support.

Configuring Port Triggering and Port Forwarding

Port Triggering is an advanced feature that can be used to easily enable gaming and other internet applications. Port Forwarding is typically used to enable similar functionality, but it is static and has some limitations.

Note: If you use applications such as multi-player gaming, peer-to-peer connections, real time communications such as instant messaging, or remote assistance (a feature in Windows XP), you should also enable UPnP according to the instructions at “Using Universal Plug and Play (UPnP)“ on page 8-20.

Port Triggering opens an incoming port temporarily and does not require the server on the internet to track your IP address if it is changed by DHCP, for example.

Port Triggering monitors outbound traffic. When the router detects traffic on the specified outbound port, it remembers the IP address of the computer that sent the data and triggers the incoming port. Incoming traffic on the triggered port is then forwarded to the triggering computer.

Using the Port Triggering page, you can make local computers or servers available to the Internet for different services (for example, FTP or HTTP), to play Internet games (like Quake III), or to use Internet applications (like CUseeMe).

Port Forwarding is designed for FTP, Web Server or other server based services. Once port forwarding is set up, request from Internet will be forwarded to the proper server. On the contrary, port triggering will only allow request from Internet after a designated port is 'triggered'. Port triggering applies to chat and Internet games.

To edit or delete a Port Forwarding entry, follow these steps.

1.In the table, select the button next to the service name.

2.Click Edit or Delete.

Local Web and FTP Server Example

If a local computer with a private IP address of 192.168.1.33 acts as a Web and FTP server, configure the Ports menu to forward HTTP (port 80) and FTP (port 21) to local address 192.168.1.33

In order for a remote user to access this server from the Internet, the remote user must know the IP address that has been assigned by your ISP. If this address is 172.16.1.23, for example, an Internet user can access your Web server by directing the browser to http://172.16.1.23. The assigned IP address can be found in the Maintenance Status Menu, where it is shown as the WAN IP Address.

Some considerations for this application are:

If your account’s IP address is assigned dynamically by your ISP, the IP address may change periodically as the DHCP lease expires.

If the IP address of the local computer is assigned by DHCP, it may change when the computer is rebooted. To avoid this, you can manually configure the computer to use a fixed address.

Local computers must access the local server using the computers’ local LAN address (192.168.1.33 in this example). Attempts by local computers to access the server using the external IP address (172.16.1.23 in this example) will fail.

Multiple Computers for Half Life, KALI or Quake III Example

To set up an additional computer to play Half Life, KALI or Quake III:

1.Click the button of an unused port in the table.

2.Select the game again from the Services/Games list.

3.Change the beginning port number in the Start Port box.

For these games, use the supplied number in the default listing and add +1 for each additional computer. For example, if you've already configured one computer to play Hexen II (using port 26900), the second computer's port number would be 26901, and the third computer would be 26902.

4.Type the same port number in the End Port box that you typed in the Start Port box.

5.Type the IP address of the additional computer in the Server IP Address box.

6.Click Apply.

Some online games and videoconferencing applications are incompatible with NAT. The WPN824 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 in the PORTS Menu. If one local computer acts as a game or videoconferencing host, enter its IP address as the default.

Configuring the WAN Setup Options

The WAN Setup options let you configure a DMZ server, change the MTU size and enable the wireless router to respond to a Ping on the WAN port. These options are discussed below.

Figure 8-8: WAN Setup menu.

Connect Automatically, as Required

Normally, this option should be checked to enable it. An Internet connection will be made automatically after each timeout, whenever Internet-bound traffic is detected. This provides connection on demand and is potentially cost-saving in places in Europe for example where Internet services charge by the minute.

If disabled, you must connect manually, using the “Connection Status” button on the Router Status screen. This manual connection will stay up all the time without time outs.

Disabling the SPI Firewall

The SPI (Stateful Inspection) Firewall protects your LAN against Denial of Service attacks. This should only be disabled in special circumstances.

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.

Note: DMZ servers pose a security risk. A computer designated as the default DMZ server loses much of the protection of the firewall, and is exposed to exploits from the Internet. If compromised, the DMZ server 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.

The WAN Setup menu, shown below lets you configure a Default DMZ Server.

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

1.Click WAN Setup link on the Advanced section of the main menu.

2.Type the IP address for that server. To remove the default DMZ server, replace the IP address numbers with all zeros.

3.Click Apply.

Responding to Ping on Internet WAN Port

If you want the router to respond to a 'ping' from the Internet, click 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. Don't check this box unless you have a specific reason to do so.

Setting the MTU Size

The normal MTU (Maximum Transmit Unit) value for most Ethernet networks is 1500 Bytes, 1492 Bytes for PPPoE connections, or 1436 for PPTP 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.

Any packets sent through the router that are larger than the configured MTU size will be repackaged into smaller packets to meet the MTU requirement. To change the MTU size:

1.Under MTU Size, enter a new size between 64 and 1500.

2.Click Apply to save the new configuration.

Using the LAN IP Setup Options

Another feature category under the Advanced heading is LAN IP Setup. This menu allows configuration of LAN IP services such as DHCP and RIP. From the Main Menu of the browser interface, under Advanced, click on LAN IP Setup to view the LAN IP Setup menu, shown below.

Reference Manual for the RangeMax Wireless Router WPN824

Configuring LAN TCP/IP Setup Parameters

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—192.168.1.1

Subnet mask—255.255.255.0

These addresses are part of the 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.

The LAN IP 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.

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. RIP-2B uses subnet broadcasting.

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.

Using the Router as a DHCP server

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 computers 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-10 for an explanation of DHCP and information about how to assign IP addresses for your network.

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 checked.

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 192.168.1.2 and 192.168.1.253, although you may wish 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 (the router’s LAN IP address)

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

Using Address Reservation

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 192.168.1.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.

Using a Dynamic DNS Service

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, who 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.

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.

8-16

Advanced Configuration of the Router

202-10072-01, March 2005

Reference Manual for the RangeMax Wireless Router WPN824

The router contains a client that can connect to many popular dynamic DNS services. You can select one of these services and obtain an account with them. Then, 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.

From the Main Menu of the browser interface, under Advanced, click on Dynamic DNS. To configure Dynamic DNS:

1.Register for an account with one of the dynamic DNS service providers whose names appear in the ‘Select Service Provider’ box. For example, for dyndns.org, go to www.dyndns.org.

2.Select the Use a dynamic DNS service check box.

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

4.Type the Host Name (or domain name) that your dynamic DNS service provider gave you.

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

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

7.If your dynamic DNS provider allows the use of wildcards in resolving your URL, you may 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

8.Click Apply to save your configuration.

Configuring 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.

From the Main Menu of the browser interface, under Advanced, click on Static Routes to view the Static Route menu, shown below.

8.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.

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

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 192.168.1.100.

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 gateway, and a second static route was created to your local network for all 192.168.1.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 192.168.1.100. The static route would look like Figure 8-11.

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 Gateway IP Address fields specifies that all traffic for these addresses should be forwarded to the ISDN router at 192.168.1.100.

A Metric value of 1 will work since the ISDN router is on the LAN.

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

Enabling Remote Management Access

Using the Remote Management page, you can allow a user or users on the Internet to configure, upgrade and check the status of your WPN824 router.

Note: Be sure to change the router's default configuration 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.

To configure your router for Remote Management:

1.Select the Turn Remote Management On check box.

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

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

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

b.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.

c.To allow access from a single IP address on the Internet, select Only this computer. Enter the IP address that will be allowed access.

3.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, 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.

4.Click Apply to have your changes take effect.

Note: When accessing your router from the Internet, you will type your router's WAN IP address into your browser's Address (in IE) or Location (in Netscape) box, followed by a colon (:) and the custom port number. For example, if your external address is 134.177.0.123 and you use port number 8080, you must enter http://134.177.0.123:8080 in your browser.

Using 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.

Figure 8-12. UPnP Menu

From the Main Menu of the browser interface, under Advanced, click on UPnP. Set up UPnP according to the guidelines below.

Turn UPnP On: 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.

Note: If you use applications such as multi-player gaming, peer-to-peer connections, real time communications such as instant messaging, or remote assistance (a feature in Windows XP), you should enable UPnP.

Advertisement Period: The Advertisement Period is how often the router will broadcast its UPnP information. This value can range from 1 to 1440 minutes. The default period is 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. The time to live hop count is the number of steps a broadcast packet is 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.
