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 UplinkTM 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

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).
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.
