—802.11g-only

—802.11b-only

•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.

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

A Powerful, True Firewall

Unlike simple Internet sharing NAT routers, the DG834GT 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 DG834GT will log security events such as blocked incoming traffic, port scans, attacks, and administrator logins. You can configure the router to email the log to you at specified intervals. You can also configure the router to send immediate alert messages to your email address or email pager whenever a significant event occurs.

Easy Installation and Management

You can install, configure, and operate the DG834GT 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.

Introduction

2-3

August 2004

Reference Manual for the Model DG834GT 108 Mbps Super Wireless ADSL Router

•Smart Wizard

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

•Remote management

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

•Diagnostic functions

The router incorporates built-in diagnostic functions such as Ping, DNS lookup, and remote reboot. These functions allow you to test Internet connectivity and reboot the router. You can use these diagnostic functions directly from the DG834GT when you are connected on the LAN or when you are connected over the Internet via the remote management function.

•Visual monitoring

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

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

Protocol Support

The DG834GT supports Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing Information Protocol (RIP). Appendix B, “Network and Routing Basics” provides further information on TCP/IP.

•The Ability to Enable or Disable IP Address Sharing by NAT

The DG834GT allows several networked PCs to share an Internet account using only a single IP address, which may be statically or dynamically assigned by your Internet service provider (ISP). This technique, known as Network Address Translation (NAT), allows the use of an inexpensive single-user ISP account. This feature can also be turned off completely while using the DG834GT if you want to manage the IP address scheme yourself.

•Automatic Configuration of Attached PCs by DHCP

The DG834GT dynamically assigns network configuration information, including IP, router, and domain name server (DNS) addresses, to attached PCs on the LAN using the Dynamic Host Configuration Protocol (DHCP). This feature greatly simplifies configuration of PCs on your local network.

•DNS Proxy

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

2-4	Introduction

August 2004

Reference Manual for the Model DG834GT 108 Mbps Super Wireless ADSL Router

•Classical IP (RFC 1577)

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

•PPP over Ethernet (PPPoE)

PPPover 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)

PPPover ATM is a protocol for connecting remote hosts to the Internet over an ADSL connection by simulating an ATM connection.

•Dynamic DNS

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

•Universal Plug and Play (UPnP)

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

Content Filtering

With its content filtering feature, the DG834GT prevents objectionable content from reaching your PCs. The router allows you to control access to Internet content by screening for keywords within Web addresses. You can configure the router to log and report attempts to access objectionable Internet sites.

Auto Sensing and Auto Uplink™ LAN Ethernet Connections

With its internal 4-port 10/100 switch, the DG834GT 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.

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.

Chapter 3

Connecting the Router to the Internet

This chapter describes how to set up the router on your Local Area Network (LAN) and connect to the Internet. It describes how to configure your DG834GT 108 Mbps Super Wireless ADSL Router for Internet access using the Setup Wizard, or how to manually configure your Internet connection.

What You Need Before You Begin

You need to prepare the following before you can establish an Internet connection through your router:

1.The router connected to an ADSL line and a computer properly connected to the router as explained below.

2.Active Internet service such as that provided by an ADSL account.

3.The Internet Service Provider (ISP) configuration information for your DSL account.

Note: If you purchased the DG834GT in a country where a microfilter is not included, you must acquire one.

ADSL Microfilter Requirements

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.

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

Note: Do not connect the DG834GT to the ADSL line through a microfilter unless the microfilter is a combination microfilter/splitter specifically designed for this purpose. Doing so will prevent the built-in ADSL modem in the DG834GT from establishing a connection to the Internet. If you have any doubts about this, connect the DG834GT directly to the ADSL line.

Figure 3-2: ADSL microfilter with built-in splitter

Use an ADSL microfilter with built-in splitter when there is a single wall outlet which must provide connectivity for both the DG834GT and telephone equipment.

Ethernet Cabling Requirements

The DG834GT Super Wireless ADSL Router connects to your Ethernet LAN via twisted-pair cables. If the computer will connect to your network at 100 Mbps, you must use a Category 5 (CAT5) cable such as the one provided with your router.

Computer Hardware Requirements

To use the DG834GT Super Wireless ADSL Router on your network, each computer must have an installed Ethernet adapter and an Ethernet cable, or a 802.11g wireless adapter.

LAN Configuration Requirements

For the initial connection to the Internet and configuration of your router, you need to connect a computer to the router which is set to automatically get its TCP/IP configuration from the router via DHCP.

Note: Please refer to Appendix C, “Preparing Your Network” for assistance with DHCP configuration.

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 router to the Internet:

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

•Multiplexing Method

•Host and Domain Names

•ISP Login Name and Password

•ISP Domain Name Server (DNS) Addresses

•Fixed or Static IP Address

Where Do I Get the Internet Configuration Parameters?

There are several ways you can gather the required Internet connection information.

•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 or you can try one of the options below.

•If you have a computer already connected using the active Internet access account, you can gather the configuration information from that computer.

•For Windows 95/98/ME, open the Network control panel, select the TCP/IP entry for the Ethernet adapter, and click Properties.

•For Windows 2000/XP, open the Local Area Network Connection, select the TCP/IP entry for the Ethernet adapter, and click Properties.

•For Macintosh computers, open the TCP/IP or Network control panel.

•You can also refer to the DG834GT Resource CD for the NETGEAR Router ISP Guide which provides Internet connection information for many ISPs.

Once you locate your Internet configuration parameters, you may want to record them on the next page.

Record Your Internet Connection Information

Print the following page. Fill in the configuration parameters from your Internet Service Provider (ISP).
