Introduction
This chapter describes the features of the NETGEAR 54 Mbps ADSL Modem Wireless Router
Model DG834G. 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 DG834G 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
v1.2, October 2006
Reference Manual for the ADSL Modem Wireless Router DG834G
Key Features
The ADSL Modem Wireless Router provides the following features:
• A built-in ADSL modem
• A powerful, true firewall
• 802.11g standards-based wireless networking
• Easy, Web-based setup for installation and management
• Extensive Internet protocol support
• Trustworthy VPN Communications over the Internet
• VPN Wizard for easy VPN configuration
• Auto Sensing and Auto Uplink™ LAN Ethernet connections
• Content filtering
• Wi-Fi Multimedia (WMM) QoS (Quality of Service) to prioritize voice and video traffic
These features are discussed below.
A Powerful, True Firewall
Unlike simple Internet sharing NAT routers, the DG834G v3 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 DG834G v3 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
v1.2, October 2006
Reference Manual for the ADSL Modem Wireless Route r DG 834G
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) enc ryption
and 802.1x authentication
• Wireless access can be restricted by MAC address
Easy Installation and Management
You can install, configure, and operate the DG834G v3 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 the DG834G v3 when you are
connected on the LAN or when you are connected over the Internet via the remote
management function.
Introduction 2-3
v1.2, October 2006
Reference Manual for the ADSL Modem Wireless Router DG834G
• 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 DG834G v3 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 DG834G v3 allows several networked PCs to share an Internet accoun t 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 DG834G v3 if you want to manage the IP address scheme yourself.
• Automatic Configuration of Attached PCs by DHCP
The DG834G v3 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.

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.
• VPN Wizard based on VPNC recommended settings.
Auto Sensing and Auto Uplink™ LAN Ethernet Connections
With its internal 4-port 10/100 switch, the DG834G v3 can co nn ec t 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 modem router incorporates Auto Uplink
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 DG834G v3 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.

Manual Setup
Use the topics and procedures below to manually set up your modem router.
What You Need Before Yo u Begin
You need to prepare the following before you can set up your firewall:
• Active Internet service provided by an ADSL account.
Configuring Your Internet Connection 3-1
v1.2, October 2006
Reference Manual for the ADSL Modem Wireless Router DG834G
• 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.
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 th ese
configuration parameters to connect your firewall to the Internet:
• Virtual Path Identifier (VPI)/Vi rtual 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.

Figure 3-2
Line
Use an ADSL microfilter with built-in splitter when there is a single wall outlet which must
provide connectivity for both the modem router and telephone equipment.
Computers Set to DHCP
For the initial connection to your firewall, your computer has to be set to automatically get its
TCP/IP configuration from the firewall via DHCP. This is usually the case. The NETGEAR Smart
Wizard CD automatically takes care of this requirement. For manual setup, refer to the
documentation that came with your computer.
