Introduction

This chapter describes the features of the NETGEAR DG834 ADSL Firewall Router. The DG834 ADSL router is a combination of a built-in ADSL modem, router, 4-port switch, and firewall which enables your entire network to safely share an Internet connection that otherwise is used by a single computer.

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

and Routing Basics” to become more familiar with the terms and procedures used in this

manual.

About the Router

The DG834 ADSL Firewall Router provides continuous, high-speed 10/100 Ethernet access between your Ethernet devices. The DG834 ADSL router enables your entire network to share an Internet connection through the built-in ADSL modem that otherwise is used by a single computer. With minimum setup, you can install and use the router within minutes.

The DG834 ADSL router provides multiple Web content filtering options, plus e-mail browsing activity reporting and instant alerts. Parents and network administrators can establish restricted access policies based on time-of-day, Web site addresses and address keywords, and 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

Reference Manual for the Model DG834 ADSL Firewall Router

Key Features

The DG834 ADSL router provides the following features :

• A powerful, true firewall

• Content filtering

• Auto Sensing and Auto Uplink™ LAN Ethernet connections

• Extensive Internet protocol support

• Easy, Web-based setup for installation and management

• A built-in ADSL modem These features are discussed below.

A Powerful, True Firewall

Unlike simple Internet sharing NAT routers, the DG834 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 DG834 will log security events such as blocked incoming traffic, port scans, attacks, and administrator logins. Y ou 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.

Content Filtering

With its content filtering feature, the DG834 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.

2-2 Introduction

Reference Manual for the Model DG834 ADSL Firewall Router

Auto Sensing and Auto Uplink™ LAN Ethernet Connections

With its internal 4-port 10/100 switch, the DG834 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.

The router incorporates Auto Uplink

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.

Protocol Support

The DG834 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 DG834 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 for using the DG834 if you want to manage the IP address scheme yourself.

• Automatic Configuration of Attached PCs by DHCP

The DG834 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.

• 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.

Introduction 2-3

Reference Manual for the Model DG834 ADSL Firewall Router

• 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.

• 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 among networking technology. 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.

Easy Installation and Management

You can install, configure, and operate the DG834 within minutes after connecting it to the network. The following features simplify installation and management tasks:

• Browser-based management

Browser-based configuration allows you to easily configure your router from almost any type of personal computer, such as Windows, Macintosh, or Linux. A user-friendly Setup Wizard is provided and online help documentation is built into the browser-based Web Management Interface.

• Smart Wizard

The 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 login 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.

2-4 Introduction

Reference Manual for the Model DG834 ADSL Firewall Router

• 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 DG834 when your are connect 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 upgrade

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 DG834 ADSL Firewall 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 DG834 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.

ADSL Microfilter

Phone

Figure 3-1: ADSL microfilter

Connecting the Router to the Internet 3-1

Reference Manual for the Model DG834 ADSL Firewall Router

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

Note: Do not connect the DG834 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 DG834 from establishing a connection to the Internet. If you have any doubts about this, connect the DG834 directly to the ADSL line.

ADSL Microfilter with Built-In Splitter

DSL Phone

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

Line

Use an ADSL microfilter with built-in splitter when there is a single wall outlet which must provide connectivity for both the DG834 and telephone equipment.

Ethernet Cabling Requirements

The DG834 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 DG834 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.

3-2 Connecting the Router to the Internet

Reference Manual for the Model DG834 ADSL Firewall Router

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.

Connecting the DG834 to Your LAN

This section provides instructions for connecting the DG834 ADSL router.

Note: The Resource CD included with your router contains an animated Installation Assistant to

help you through this procedure.

How to Connect the Router

There are four steps to connecting your firewall:

1. Connect the router to your ADSL line.

2. Connect the router to the computers on your network.

3. Log in to the router.

4. Connect to the Internet.

Follow the steps below to connect your router to your network. Before you begin, locate the ADSL configuration information from your Internet Service Provider (ISP).

1. CONNECT THE DG834 TO THE ADSL LINE.

a. You need to install a filter on every telephone or device that shares the same phone

number as your ADSL router. Select the filter that came with your router.

Note: To use a one-line filter with a separate splitter, insert the splitter into the phone outlet, connect the one-line filter to the splitter, and connect the phone to the filter.

2. CONNECT THE DG834 TO THE INTERNET.

Note: Improperly connecting a filter to your DG834 ADSL router will block your ADSL connection.

a. Turn off your computer. b. Connect the ADSL port of the DG834 to the ADSL port (B) of the two-line filter:

Figure 3-6: Connecting a computer to the DG834 ADSL router

Note: The DG834 ADSL router incorporates Auto UplinkTM technology. Each Ethernet LAN port will automatically sense whether the cable plugged into the port should have a 'normal' connection (for example, connecting to a computer) or an 'uplink' connection (for example, connecting 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.

d. Connect the power adapter to the router and plug it in to a power outlet. Verify the

following:

The power light is lit after turning on the router. The ADSL link light is solid green, indicating a link has been established to the

ADSL network.

e. Now, turn on your computer. If software usually logs you in to your Internet connection,

do not run that software or cancel it if it starts automatically. Verify the following:

The local lights are lit for any connected computers.

Note: For instructions on connecting computers to the DG834 via wireless links, please see the Chapter 4, “Wireless Configuration”.
