Reference Manual for the 54 Mbps Wireless ADSL Firewall Router DG834G
• The Ability to Enable or Disable IP Address Sharing by NAT
The DG834G allows several networked computers 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 DG834G if you want to manage the IP address scheme yourself.
• Automatic Configuration of Attached Computers by DHCP
The DG834G dynamically assigns network configuration information, including IP, gateway,
and domain name server (DNS) addresses, to attached computers on the LAN using the
Dynamic Host Configuration Protocol (DHCP). This feature greatly simplifies configuration
of computers 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 computers. 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 among networking technology.
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.
