Introduction

This chapter describes the features of the NETGEAR 54 Mbps ADSL Modem Wireless Router Model DG834GSP. The ADSL Modem Wireless Router is a combination of a built-in ADSL modem, modem router, 4-port switch, and firewall which enables your entire network to safely share an Internet connection that otherwise would be used by a single computer.

Note: If you are unfamiliar with networking and routing, refer to “Internet Networking

and TCP/IP Addressing” in Appendix C to become more familiar with the terms

and procedures used in this manual.

About the Modem Router

The 54 Mbps ADSL Modem Wireless Router Model DG834GSP provides continuous, high-speed 10/100 Ethernet access between your Ethernet devices. With minimum setup, you can install and use the modem router within minutes.

The ADSL Modem Wireless Router provides multiple Web content filtering options, 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 ADSL Internet access for up to 253 personal computers. The included firewall and Network Address Translation (NAT) features protect you from hackers.

Introduction 2-1

v1.0, June 2007

Reference Manual for the ADSL Modem Wireless Router DG834GSP

Key Features

The ADSL Modem Wireless Router provides the following features:

• A built-in ADSL modem

A Powerful, True Firewall

Unlike simple Internet sharing NAT routers, the DG834GSP 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 DG834GSP will log security events such as blocked incoming traffic, port scans, attacks, and administrator logins. You can configure the modem router to email the log to you at specified intervals. Y ou can also configure the modem router to send immediate alert messages to your email address or email pager whenever a significant event occurs.

2-2 Introduction

v1.0, June 2007

Reference Manual for the ADSL Modem Wireless Router DG834GSP

802.11 Standards-based Wireless Networking

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

• 802.11g Standards-based wireless networking at up to 54 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 Wi-Fi Protected Access Pre-Shared Key (WPA-PSK and WPA2-PSK) encryption and 802.1x authentication

• Wireless access can be restricted by MAC address

Easy Installation and Management

You can install, configure, and operate the DG834GSP 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 modem 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 firmware in the modem router automatically senses the type of Internet connection, asking you only for the information required for your type of ISP account.

• Remote management The modem 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, or you can choose a nonstandard port number.

• Diagnostic functions The modem 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 modem router. You can use these diagnostic functions directly from th e DG834GSP when you are connected on the LAN or when you are connected over the Internet via the remote management function.

Introduction 2-3

v1.0, June 2007

Reference Manual for the ADSL Modem Wireless Router DG834GSP

• Visual monitoring The modem 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.

Protocol Support

The DG834GSP supports Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing Information Protocol (RIP). “Internet Networking and TCP/IP Addressing” in Appendix C provides further information on TCP/IP.

• The Ability to Enable or Disable IP Address Sharing by NAT The DG834GSP 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 comp let ely while using the DG834GSP if you want to manage the IP address scheme yourself.

• Automatic Configuration of Attached PCs by DHCP The DG834GSP dynamically assigns network configuration information, including IP, modem 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 modem router provides its own address as a DNS server to the attached PCs. The modem router obtains actual DNS addresses from the ISP during connection setup and forwards DNS requests from the LAN.

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

• PPP over Ethernet (PPPoE) PPP over Ethernet is a protocol for connecting remote hosts to the Internet over an ADSL connection by simulating a dial-up connection. This feature eliminates the need to run a login program such as EnterNet or WinPOET on your computer.

• PPP over ATM (PPPoA) PPP over ATM is a protocol for connecting remote hosts to the Internet over an ADSL connection by simulating an ATM connection.

2-4 Introduction

v1.0, June 2007

Reference Manual for the ADSL Modem Wireless Router DG834GSP

• Point-to-Point Tunneling Protocol (PPTP) Typically used as a protocol for virtual private networks. This protocol is used by some Russian ISPs for connecting remote hosts to the Internet over an ADSL connection.

Note: PPTP must be manually configured. At present, the SmartWizard cannot

automatically detect a PPTP type of connecton with your 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 modem 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.

Virtual Private Networking (VPN)

The ADSL Modem Wireless Router provides a secure encrypted connection between your local area network (LAN) and remote networks or clients. It includes the following VPN features:

• Supports 5 VPN connections.

• Supports industry standard VPN protocols The ADSL Modem Wireless Router supports standard Manual or IKE keying methods, standard MD5 and SHA-1 authentication methods, and standard DES and 3DES encryption methods. It is compatible with many other VPN products.

• Supports 3DES encryption for maximum security.

With its internal 4-port 10/100 switch, the DG834GSP 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.

Introduction 2-5

v1.0, June 2007

Reference Manual for the ADSL Modem Wireless Router DG834GSP

The modem router incorporates Auto UplinkTM technology. Each local 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.

Content Filtering

With its content filtering feature, the DG834GSP prevents objectionable content from reaching your PCs. The modem router allows you to control access to Internet content by screening for keywords within W eb addresses. You can configure the modem router to log and report attempts to access objectionable Internet sites.

Wi-Fi Multimedia (WMM) Quality of Service (QoS)

WMM is a QoS feature that provides prioritization of wireless data packets from different applications based on four access categories: voice, video, best effort, and background. For an application to receive the benefits of WMM QoS, both it and the client running that application must be WMM-enabled. Legacy applications that do not support WMM, and applications that do not require QoS, are assigned to the best-effort category, which receives a lower priority than voice and video.

Chapter 3

Configuring Your Internet Connection

This chapter describes how to configure the wired internet connection of your 54 Mbps ADSL Modem Wireless Router Model DG834GSP.

Connecting the Router to the Internet

To connect your ADSL Modem Wireless Router to the Internet, refer to the ADSL Modem Wirelesss Route r Setup Manual on the DG834GSP ADSL Modem Wireless Router Resource CD

Manual Setup

Note: The most reliable way to set up your modem router is by performing the setup from

the CD, because it will be tailored to the configuration requirements of your ISP. You will only need to perform a setup from your router’s configuration utility if you change your ISP or you are troubleshooting your connection.

Use the topics and procedures below to manually set up your modem router.

What You Need Before You Begin

You need to prepare the following before you can set up your modem router:

• Active Internet service provided by an ADSL account.

• The Internet Service Provider (ISP) configuration information for your ADSL account. – ISP Login Name and Password – ISP Domain Name Server (DNS) Addresses – Fixed or Static IP Address

• ASDL microfilters as explained below.

• Your computers set to DHCP.

Configuring Your Internet Connection 3-1

v1.0, June 2007

Reference Manual for the ADSL Modem Wireless Router DG834GSP

Your ISP should have provided you with all the information needed to connect to the Internet. If you cannot locate this information, you can ask your ISP to provide it.

Internet Configuration Requirements

Depending on how your ISP set up your Internet account, you need one or more of these configuration parameters to connect your modem router to the Internet:

• Virtual Path Identifier (VPI)/Virtual Channel Indentifier (VCI) parameters

• Multiplexing Method

• Host and Domain Names

Understanding ADSL Microfilters

ADSL technology uses the same wires as your telephone service. However, ADSL adds signals to the telephone lines which create noise in the telephone service. You must use ADSL microfilters to filter out these signals before they reach your telephone.

Note: If you purchased the modem router in a country where a microfilter is not included,

you must acquire one.

ADSL Microfilter

Phone

Figure 3-1

Each device such as a telephone, fax machine, answering machine, or caller ID display will require an ADSL microfilter.

Warning: Do not connect the modem router to the ADSL line through a microfilter

unless the microfilter is a combination microfilter/splitter specifically designed for this purpose. Doing so will prevent block your connection to the Internet. If you have any doubts about this, connect the modem router directly to the ADSL line.

Chapter 4

Wireless Configuration

This chapter describes how to configure the wireless features of your 54 Mbps ADSL Modem Wireless Router Model DG834GSP.

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 modem router in order to maximize the network speed.

To ensure proper compliance and compatibility between similar products in your area, the operating channel and region must be set correctly.

Observe Performance, Placement, and Range Guidelines

The operating distance or range of your wireless connection can vary significantly bas ed on the physical placement of the wireless modem router. 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 modem router:

• 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, microwave s, and cordless phones

• With the Antenna tight and in the upright position

• Away from large metal surfaces

Wireless Configuration 4-1

v1.0, June 2007

Reference Manual for the ADSL Modem Wireless Router DG834GSP

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 ADSL Modem Wireless Router provides highly effective security features which are covered in detail in this chapter. Deploy the security features appropriate to your needs.

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 DG834GSP. Restrictin g 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.

• 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. This data encryption mode has been superseded by WPA-PSK and WPA2-PSK.

• WPA-802.1x, WPA2-802.1x. Wi-Fi Protected Access (WPA) with user authentication implemented using IEE 802.1x and RADIUS servers.

• WPA-PSK (TKIP), WPA2-PSK (AES). Wi-Fi Protected Access (WPA) using a pre-shared key to perform authentication and generate the initial data encryption keys. The very strong authentication along with dynamic per frame re-keying of WPA make it virtually impossible to compromise. Because this is a relatively new standard, wireless device driver and software availability may be limited.

Understanding Wireless Settings

To configure the Wireless interface of your modem router, click the Wireless Settings link in the Setup section of the main menu. The Wireless Settings menu will appear, similar to that shown below:

Figure 4-2

4-4 Wireless Configuration

v1.0, June 2007

Reference Manual for the ADSL Modem Wireless Router DG834GSP

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 a unique value printed on the label on the bottom of your modem router.

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

wireless.

Since your default SSID is unique, there is no good reason for changing its value. If you do change the value, performing a hard reset will restore the SSID to its default.

— Region. Select your country/region from the drop-down list. This field displays the region

of operation for which the wireless interface is intended.

— Channel. This field determines which operating frequency will be used. The default

channel is selected by encoding the MAC address. It should not be necessary to change the wireless channel unless you notice interference problems with another nearby access point.

— 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; 802.1 1g 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 modem router. The wireless icon on the front of the modem 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 that have no SSID (or a "null" value) ca n then adopt the correct SSID for connections to this Access Point.

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

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

change the modem router’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 modem router’s new settings.

7. Configure and test your computers for wireless connectivity. Program the wireless adapter of your computers to have the same SSID and encryption type

and passphrase as you configured in your modem router. Check that they have a wireless link and are able to obtain an IP address by DHCP from the modem router.

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

How to Restrict Wireless Access to Your Network

By default, any wireless PC that is configured with the correct SSID and WPA-PSK network key will be allowed access to your wireless network. This will be sufficient to deter all but the most determined hackers. The 54 Mbps ADSL Modem Wireless Router Model DG834GSP provides several ways to further restrict wireless access to your network:

• Turn off wireless connectivity completely

• Hiding your Wireless Network Name (SSID)

• Restrict access based on the Wireless Card Access List

4-8 Wireless Configuration

v1.0, June 2007

Reference Manual for the ADSL Modem Wireless Router DG834GSP

These options are discussed below.

Figure 4-3

Restricting Access to Your Network by Turning Off Wireless Connectivity

You can completely turn off the wireless portion of the DG834GSP. 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.

Hiding Your Wireless Network Name (SSID)

The DG834GSP 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 DG834GSP. You must configure your wireless devices to match the wireless network name (SSID) you configure in the ADSL Modem Wireless Router.

Note: The SSID of any wireless access adapters must match the SSID you configure in

the 54 Mbps ADSL Modem Wireless Router Model DG834GSP. If they do not match, you will not get a wireless connection to the DG834GSP.

Restricting Wireless Access Based on the Wireless Station Access List

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

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

Choosing WEP Authentication and Security Encryption Methods

Warning: WEP is an older sec urity standard than WPA and is easier to compromise.

Only use this form of security if one or more of your wireless clients does not support WPA security.

Figure 4-5

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 DG834GSP lets you select the following wireless authentication schemes.

• Automatic

• Open System

Wireless Configuration 4-13

v1.0, June 2007

• 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 ADSL Modem Wireless Router. Please refer to

“Wireless Communications” in Appendix C for a full

explanation of each of these options, as defined by the IEEE 802.11g wireless communication standard.

Configuring Basic Firewall Services

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

Blocking Keywords, Sites, and Services

The modem router provides a variety of options for blocking Internet-based content and communications services. With its content filtering feature, the ADSL Modem Wireless Router prevents objectionable content from reaching your PCs. The modem 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 modem router to perform these functions.

How to Block Keywords and Sites

The ADSL Modem Wireless Router allows you to restrict access to Internet content based on functions such as Web addresses and Web address keywords.

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 DG834GSP 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 destinat ion 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.

v1.0, June 2007

Reference Manual for the ADSL Modem Wireless Router DG834GSP

Inbound Rules (Port Forwarding)

Because the DG834GSP 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 inboun d 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 modem 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:

Inbound Rule Example: A Local Public Web Server

If you host a public W eb ser ver 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:

Figure 5-4

Protecting Your Network 5-7

Reference Manual for the ADSL Modem Wireless Router DG834GSP

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:

– 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.

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 server’s local LAN address (10.1.1.2 in the example above). Attempts by local computers to access the server using the external WAN IP address will fail.

5-8 Protecting Your Network

v1.0, June 2007

Reference Manual for the ADSL Modem Wireless Router DG834GSP

Outbound Rules (Service Blocking)

The DG834GSP 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 modem 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:

Figure 5-6

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.

This chapter describes how to configure the advanced features of your 54 Mbps ADSL Modem Wireless Router Model DG834GSP.

Configuring Advanced Security

The 54 Mbps ADSL Modem Wireless Router Model DG834GSP 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

These features are discussed below.

Advanced Configuration 7-1

v1.0, June 2007

Reference Manual for the ADSL Modem Wireless Router DG834GSP

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 modem ro uter 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.

Warning: 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 modem 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 as sign a computer or server to be a Default DMZ server, follow these steps:

7-2 Advanced Configuration

v1.0, June 2007

Figure 7-1

3. Select the Default DMZ Server check box.

4. Type the IP address for that server.

5. Click Apply to save your changes.

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.

Advanced Configuration 7-3

v1.0, June 2007

Reference Manual for the ADSL Modem Wireless Router DG834GSP

Enable PPPoE-Relay

When enabled, this feature allows a PPPoE client on a local PC to a remote PPPoE server with the gateway acting as a relay agent.

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 modem 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 modem router to be discovered. Do not select this box unless yo u 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 modem router is shipped preconfigured to use private IP addresses on the LAN side, and to act as a DHCP server. The modem router’s default LAN IP configuration is:

• LAN IP addresses—10.1.1.1

• Subnet mask—255.255.255.0
