Reference Manual for the ADSL Modem Router DG834 v3
2-4 Introduction
v1.1, October 2006
• Automatic Configuration of Attached PCs by DHCP
The DG834 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.
• 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 modem 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 between networking
technologies. 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.
