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.

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:

• Smart Wizard Internet Connection Setup
The WGT634U W ireless Media Router Smart W izard automatically senses the type of Internet
connection, asking you only for the information required for your type of ISP account.
• Smart Wizard External USB Disk Setup
The WGT634U Wireless Media Router Smart Wizard automatically senses the addition of a
plug-in USB device and assists in the configuration.
• Firmware Auto-Update
When you log in to the WGT634U W ireless Media Router, the menu asks if you want to check
the Internet to see if a newer version of firmware is available. If so, the configuration screen
asks if you want to install the upgrade. This lets you take advantage of product enhancements
for your WGT634U as soon as they become available.
• Visual monitoring
The WGT634U W ireless Media Router’s front panel LEDs provide an easy way to monitor its
status and activity.

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.
