These features are discussed below.

Modem or Router Device Mode

The DG632 modem router can be set to operate in either Modem Device Mode or Router Device
Mode.

Modem Device Mode

When set to operate in Modem Device Mode, your computer must be configured for whatever
settings your ISP requires. Also, if your ISP uses software to establish your Internet connection,
the DHCP spoofing feature will eliminate the need to run that software.
When DHCP spoofing is enabled, the modem obtains the actual Internet WAN IP address from the
ISP during connection setup and forwards it to the attached computer.

Router Device Mode

In Router Device Mode, the DG632 supports configuration of the Transmission Control Protocol/
Internet Protocol (TCP/IP) parameters and login functions on the modem.
The DG632 supports Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing
Information Protocol (RIP).
information on TCP/IP.
• Automatic Configuration of Attached PCs by DHCP
The DG632 dynamically assigns network configuration information, including IP, modem,
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 provides its own
address as a DNS server to the attached PCs. The modem obtains actual DNS addresses from
the ISP during connection setup and forwards DNS requests from the LAN.
