DG834G Reference Manual
• Visual monitoring
The ADSL 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 supports Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing
Information Protocol (RIP).
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, ADSL
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 ADSL modem router
provides its own address as a DNS server to the attached PCs. The ADSL 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 ADSL 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.
