RIP-1 is adequate for most networks and involves less overhead.

DHCP Service
Dynamic Host Configuration Protocol (DHCP) allows network clients to dynamically
obtain TCP/IP configuration information upon bootup. When a DHCP client starts, it
broadcasts a DHCP request. The Gateway can be set up to respond to the client
with configuration information (including, an IP address, subnet mask and default IP
gateway) or to relay the request to another DHCP server.
The Gateway can be configured with an client pool of up to 254 IP addresses. These
addresses are leased to the requesting client for a specified amount of time, or until
the device surrenders the address during shut-down. Windows 95, 98, NT, 2000,
and Vista hosts as well as other systems that provide DHCP client services can be
configured with a TCP/IP address provided by this Gateway.
DNS Service
The DNS protocol is used to map host names to IP addresses. The Gateway can
specify a well-known DNS server, or relay service requests directly through to the
ISP for resolution.
NAT Functions
Network Address Translation (NAT) allows you to map multiple IP addresses for
clients from your local Ethernet through to the Internet using a single IP address for
the VDSL port. This allows multiple users to access the Internet using a single-user
account from your ISP.
