Protocol Support

The DG834G v3 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 DG834G v3 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 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.
