Introduction

Congratulations on your purchase of the NETGEAR® 108 Mbps Wireless Media Router
WGT634U. The WGT634U Wireless Media Router provides connection for multiple personal
computers (PCs) 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 PC.

By connecting a storage device to the WGT634U through the integrated USB 2.0 interface, you
can store and share files and entertainment content for access from PC and Web applications on
computers connected on the home network as well as from the Internet. This chapter describes the
features of the NETGEAR 108 Mbps Wireless Media Router WGT634U.

Introduction to the WGT634U Wireless Media Router

The 108 Mbps Wireless Media Router WGT634U 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 WGT634U Wireless Media Router provides you with multiple Web content filtering options,
plus browsing activity reporting and instant alerts — both via e-mail. Parents and network
administrators can establish restricted access policies based on time-of-day, Web site addresses
and address keywords, and share high-speed cable/DSL Internet access for up to 253 personal
computers. In addition to the Network Address Translation (NAT) feature, the built-in firewall
protects you from hackers.

Home networks initially gained popularity for broadband Internet sharing through wired (first
generation) and wireless (second generation) routers. The addition of Internet-enabled appliances
is leading to the ‘third generation’ of performance and functionality from wireless routers. The
WGT634U is a third generation wireless router that allows router-attached storage and provides
fast wireless access. It enables you to store and stream files, audio, and video content from a
high-capacity USB-enabled disk drive. You can take advantage of advanced networking functions
such as application-level access to music, photo and other PC files as well as remote access to a
home portal.

With minimum setup, you can install and use the router within minutes.

DMZ Support

DMZ stands for Demilitarized Zone. This feature allows one IP Address to be exposed to the
Internet. DMZ allows only one computer to be exposed when multiple TCP/IP ports need to be
open. If you want to use DMZ, it is recommended that you set up a computer with a static IP.

When DMZ is used, all specific requests are forwarded to the DMZ host. The exposed user’s
computer does not share the public IP with the router.

802.11g Wireless Networking

The WGT634U Wireless Media Router includes an 802.11g wireless access point, providing
continuous, high-speed 54 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, 802.1 1-turbo-g-only,
or 802.11b+g 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.

• Wireless access can be restricted by MAC address.

A Powerful, True Firewall with Content Filtering

Unlike simple Internet sharing NAT routers, the WGT634U 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.

• The WGT634U blocks objectionable conten t 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 WGT634U Wireless Media Router is equipped with several features designed to maintain
security, as described in this section.

• PCs 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.

• 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.

• Logs security incidents.
The WGT634U 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.

Autosensing Ethernet Connections with Auto Uplink

With its internal 8-port 10/100 switch, the WGT634U 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.

2-4 Introduction

April 2004, 202-10018-02

Reference Manual for the 108 Mbps Wireless Media Router WGT634U

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 WGT634U Wireless Media 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 WGT634U Wireless Media 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 PCs by DHCP
The WGT634U Wireless Media Router dynamically assigns network configuration
information, including IP, gateway, 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 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.

• 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 PC.

Easy Installation and Management

You can install, configure and operate the 108 Mbps Wireless Media Router WGT634U within
minutes after connecting it to the network. The following features simplify installation and
management tasks:

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.

Internet or connecting to the wireless router.

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.

Be sure to restart your network in the correct sequence.

Follow this sequence. Turn off the modem, wireless router, and computer. Turn on the modem
first and wait two minutes. Next turn on the wireless router, and finally the computers.

Make sure the Ethernet cables are securely plugged in.

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

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

Make sure the network settings are correct.

• LAN and wirelessly connected computers must be configured to obtain an IP address
automatically via DHCP. For instructions on how to do this, please see the animated tutorials
on the 108 Mbps Wireless Media Router WGRT634U Resource CD (230-10043-02) or

Appendix C, “Preparing Y our Network”.

• Some cable modem ISPs require you to set the router to use the MAC address of the computer
registered on the account. If so, in the Basic Settings menu Wireless Router MAC Address
section, 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.

Chapter 4

Wireless Configuration

This chapter describes how to configure the wireless features of your WGT634U Wireless Media
Router. In planning your wireless network, you should consider the level of security required. You
should also select the physical placement of your router in order to maximize the network speed.
For further information on wireless networking, refer to in Appendix D, “Wireless Networking

Basics”.

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 router. 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 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, 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
encryption can consume more battery power on a notebook computer.

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 WGT634U Wireless Media Router provides highly effective security
features which are covered in detail in this chapter. Deploy the security features appropriate to
your needs.

Figure 4-1: WGT634U 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 WGT634U. 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.

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

Understanding Wireless Settings

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

Figure 4-2: Wireless Settings menu

The 802.11b and 802.11g wireless networking protocols are configured in exactly the same
fashion.

Wireless Configuration 4-3

April 2004, 202-10018-02

Reference Manual for the 108 Mbps Wireless Media Router WGT634U

• 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 WGT634U default SSID is NETGEAR.

• Region. This field identifies the region where the WGT634U 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.

• Mode. This field determines which data communications protocol will be used. You can select
“g and b”, “b only,” “g only”, or “108 Mbps Turbo g only”. “g only” dedicates the WGT634U
to communicating with the higher bandwidth 802. 11g wireless devices exclusively. The “g and
b” mode provides backward compatibility with the slower 802.11b wireless devices while still
enabling 802.11g commun ications. The 108 Mbps Turbo mode only works with other 802.1 1g
turbo devices that support this turbo mode.

• 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.

Understanding WEP Authentication and Encryption

Restricting wireless access to your network 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 Scheme Selection

Figure 4-3: Encryption Strength

4-4 Wireless Configuration

April 2004, 202-10018-02

Reference Manual for the 108 Mbps Wireless Media Router WGT634U

The WGT634U lets you select the following wireless authentication schemes.

• Automatic — the router detects the authentication scheme.

• Open System — allows any device to join the network, assuming that the device SSID
matches the access point SSID. Alternatively, the device can use the “ANY” SSID option to
associate with any available Access Point within range, regardless of its SSID.

•Shared Key — only those computers that possess the correct authentication key can join the
network.

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 authentication scheme and WEP encryption settings.

Be sure to set your wireless adapter according to the authentication scheme you choose for the
WGT634U W irel ess Media Router. Please refer to “Authentication and WEP Data Encryption” on

page D-2 for a full explanation of each of these options, as defined by the IEEE 802.11 wireless

communication standard.

Encryption Strength Choices

Choose the encryption strength from the drop-down list. Please refer to “Overview of WEP

Parameters” on page D-5 for a full explanation of each of these options, as defined by the IEEE

802.11 wireless communication standard.

• Disable. No encryption will be applied. This setting is useful for troubleshooting your wireless
connection, but leaves your wireless data fully exposed.

• 64-bit or 128-bit WEP. When 64-bit or 128-bit is selected, WEP encryption will be applied.

• WPA-PSK (Wi-Fi Protected Access Pre-Shared Key). Uses WPA-PSK standard encryption.

If WEP is enabled, you can manually or automatically program the four data encryption keys.
These values must be identical on all computers and access points in your network.

There are two methods for creating WEP encryption keys:

• Passphrase. Enter a word or group of printable characters in the Passphrase box and click the
Generate button. These characters are case sensitive.

• Sharing multimedia with friends and family — sharing MP3 files, pictures, and other
multimedia with local and remote users.

• Sharing resources on your network — storing files in a central location so that you do not have
to power up a computer to perform local sharing. In addition, you can share files between
Macintosh, Linux, and PC computers by using the USB drive as a go-between the systems.

Note: As soon as you plug the USB drive in the router, local users have read and write access to

the drive using Microsoft Networking.
Users from the Internet can access the USB drive using FTP. The USB Drive Wizard will guide

you through the FTP setup process.

File Sharing Scenarios

You can share files on the USB drive for a wide variety of business and recreational purposes. The
files can be any PC, Mac, or Linux file type including text files, Word, PowerPoint, Excel, MP3,
pictures, and multimedia.

A few of the common uses are shown below.

Storing Files in a Central Location for Playing or Printing

The WGT634U W ireless Media Router enables you to move files so that a private resource can act
as a network resource. The WGT634U allows centralized storage for easy access from other
computers that have local printers, CD burners, speakers, or specialized software.

For example, the following scenario may occur in a typical family that has one high quality color
printer directly attached to a computer, but not shared on the LAN:

• The daughter has some photos on her Macintosh computer that she wants to print.

• The mother has a photo-capable color printer directly attached to her PC, but not shared on the
network.

• The mother and daughter’s computers are not visible to each other on the network.

computer with a fixed IP address.

Blocking Access to Internet Services

The WGT634U Wireless Media Router allows you to block the use of certain Internet services by
computers on your network. This is called service blocking or port filtering. The Block Services
menu is shown below:

Figure 6-2: Block Services menu

6-2 Content Filtering

April 2004, 202-10018-02

Reference Manual for the 108 Mbps Wireless Media Router WGT634U

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.

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

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 65534 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 applicatio n 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.

• Configuring Service Blocking by IP Address Range

Under “Filter IP by”, you can block the specified service for a single computer, a range of
computers (having consecutive IP addresses), or all computers on your network.

Advanced Configuration

This chapter describes how to configure the advanced features of your 108 Mbps Wireless Media
Router WGT634U. These features can be found under the Advanced heading in the main menu of
the browser interface.

Configuring Port Forwarding to Local Servers

Although the router causes your entire local network to appear as a single machine to the Internet,
you can make a local server (for example, a W eb server or game server) visible and available to the
Internet. This is done using the Port Forwarding menu. From the main menu of the browser
interface, under the Advanced heading, select Port Forwarding to view the port forwarding menu,
shown below.

Figure 8-1: Port Forwarding Menu

.

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

“Network, Routing, Firewall, and Basics”, to become more familiar with the terms and

procedures used in this manual.

Advanced Configuration 8-1

April 2004, 202-10018-02

Reference Manual for the 108 Mbps Wireless Media Router WGT634U

Use the Port Forwarding menu to configure the router to forward incoming protocols to computers
on your local network. In addition to servers for specific applications, you can also specify a
Default DMZ Server to which all other incoming protocols are forwarded. The DMZ Server is
configured in the Security Menu.

Before starting, you will need to determine which type of service, application or game you will
provide and the IP address of the computer that will provide each service. Be sure the computer’s
IP address never changes. To configure port forwarding to a local server:

1. From the Service Name box, select the service or game that you will host on your network.

If the service does not appear in the list, refer to the following section, “Adding a Port

Forwarding Custom Service”.

2. Enter the IP address of the local server in the corresponding Server IP Address box.

3. Click the Add button.

Adding a Port Forwarding Custom Service

To define a service, game or application that does not appear in the Service Name list, you must
determine what port numbers are used by the service. For this information, you may need to
contact the manufacturer of the program that you want to use. When you have the port number
information, follow these steps:

1. Click the Add Custom Service button.

2. Type a name for the service.

3. Enter the first port number in an unused Starting Port box.

4. To forward only one port, enter it again in the Ending Port box. To specify a range of ports,

enter the last port to be forwarded in the End Port box.

5. Enter the IP address of the local server in the corresponding Server IP Address box.

6. Click Apply at the bottom of the menu.

Editing or Deleting a Port Forwarding Entry

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 Service or Delete Service.

8-2 Advanced Configuration

April 2004, 202-10018-02

Reference Manual for the 108 Mbps Wireless Media Router WGT634U

Local Web and FTP Server Example

If a local PC with a private IP address of 192.168.0.33 acts as a Web and FTP server, configure the
Ports menu to forward HTTP (port 80) and FTP (port 21) to local address 192.168.0.33.

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 Router Status screen, where it is shown as the Internet Port 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 PC is assigned by DHCP, it may change when the PC is rebooted.
To avoid this, you can manually configure the PC to use a fixed address.

• Local PCs must access the local server using the PC’s local LAN address (192.168.0.33 in this
example). Attempts by local PCs to access the server using the external IP address
(172.16.1.23 in this example) will fail.

Multiple Computers for Counter-Strike, Unreal Tournament, or Quake III Example

To set up an additional computer to play Counter-Strike, Unreal Tournament, or Quake III:

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

2. Select the game again from the Service Name 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 have already configured one computer to play Counter-Strike
(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.

Advanced Configuration 8-3

April 2004, 202-10018-02

Reference Manual for the 108 Mbps Wireless Media Router WGT634U

Some online games and videoconferencing applications are incompatible with NAT. The
WGT634U Wireless Media 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 Port Forwarding menu. If one local computer acts as a game or
videoconferencing host, enter its IP address as the default.

Configuring 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 8-2: WAN Setup Menu

• Connect Automatically, as Required

Normally, this option should be enabled. 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.

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.

8-4 Advanced Configuration

April 2004, 202-10018-02

Reference Manual for the 108 Mbps Wireless Media Router WGT634U

• Disable SPI Firewall

Normally, this option should be Enabled, so that your local network will be protected by the
Stateful Packet Inspection (SPI) firewall included in the WGT634U. However, certain
communications functions like VPN may require turning off the SPI feature.

• 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 PC can run the application
properly if that PC’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 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.

• Respond to Ping on Internet WAN Port

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

• Setting the MTU Size

The default MTU size is usually fine. The normal MTU (Maximum Transmit Unit) value for
most Ethernet networks is 1500 Bytes. For some ISPs, particularly some using PPPoE, you
may need to reduce the MTU. This should not be done unless you are sure it is necessary for
your ISP.

Advanced Configuration 8-5

April 2004, 202-10018-02

Reference Manual for the 108 Mbps Wireless Media Router WGT634U

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:

Under MTU Size, enter a new size between 64 and 1500, for example, 1400. Then, click
Apply to save the new configuration.

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 which will allow you to register your domain to their IP address, and will
forward traffic directed at your domain to whatever your current IP address happens to be.

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.

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.

8-6 Advanced Configuration

April 2004, 202-10018-02

Reference Manual for the 108 Mbps Wireless Media Router WGT634U

If your dynamic DNS provider allows the use of wildcards in resolving your URL, you can

7.

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.

Using LAN IP Setup Options

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

Figure 8-3: LAN IP Setup Menu

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

Advanced Configuration 8-7

April 2004, 202-10018-02

Reference Manual for the 108 Mbps Wireless Media Router WGT634U

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 may need to restart your computer for the new IP
address setting to take effect.

8-8 Advanced Configuration

April 2004, 202-10018-02

Reference Manual for the 108 Mbps Wireless Media Router WGT634U

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 selected.

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

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

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

• An IP Address from the range you have defined

• Subnet Mask

• Gateway IP Address (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.

Advanced Configuration 8-9

April 2004, 202-10018-02

Reference Manual for the 108 Mbps Wireless Media Router WGT634U

In the IP Address box, type the IP address to assign to the computer or server

2.

(choose an IP address from the router’s LAN subnet, such as 192.168.0.X).

3. Type the MAC Address of the computer or server.

(Tip: If the computer is already present on your network, you can cop y its MAC address from
the Attached Devices menu and paste it here.)

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

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

To edit or delete a reserved address entry:

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

2. Click Edit or Delete.

How to Configure 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, select Static Routes to view the
Static Route menu, shown below.

Figure 8-5. Static Route Entry and Edit Menu

2.

Type a route name for this static route in the Route Name (This is for identification purposes
only).

3. Select Private if you want to limit access to the LAN only. The static route will not be reported

in RIP.

4. Select Active to make this route effective.

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

6. Type the IP Subnet Mask for this destination.

If the destination is a single host, type 255.255.255.255.

7. T ype the Gateway IP Address, which must be a router on the same LAN segment as the router.

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 192.168.0.100.

• Your company’s network is 134.177.0.0.

Advanced Configuration 8-11

April 2004, 202-10018-02

Reference Manual for the 108 Mbps Wireless Media Router WGT634U

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 192.168.0.x addresses. With this configuration, if you attempt to access a device on the

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

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

In this case you must define a static route, telling your router that 134.177.0.0 should be accessed
through the ISDN router at 192.168.0.100. The static route would look like Figure 8-5.

In this example:

• The Destination IP Address and IP Subnet Mask fields specify that this static route applies to
all 134.177.0.x addresses.

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

• 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 WGT634U Wireless Media Router.

Note: Be sure to change the router's default configuration password to a very secure
