Reference Manual for the Model DG834 ADSL Firewall Router
Introduction
2-3
 
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
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.
Protocol Support
The DG834 supports Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing 
Information Protocol (RIP). 
 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.
