Reference Manual for the Model Wireless ADSL Firewall Router DG834G
Introduction

•
Support for Wi-Fi Protected Access Pre-Shared Key (WPA-PSK) encryption and 802.1x
authentication
•
Wireless access can be restricted by MAC address
Easy Installation and Management
You can install, configure, and operate the DG834G 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 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 DG834G 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 DG834G 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 DG834G 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 DG834G if you want to manage the IP address scheme yourself.
•
Automatic Configuration of Attached PCs by DHCP
The DG834G 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.
•
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 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 DG834G 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 8 VPN connections.
•
Supports industry standard VPN protocols
The DG834G 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.
Content Filtering
With its content filtering feature, the DG834G 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 DG834G 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
TM
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.
