Configure
• Advanced: Clicking on the Advanced link displays the Advanced LAN IP Interface page.
• IGMP Forwarding: The default setting is Disabled. If you check this option, it will
enable Internet Group Management Protocol (IGMP) multicast forwarding. IGMP allows
a router to determine which host groups have members on a given network segment.
RIP Send Mode: Specifies whether the gateway should use Routing Information Proto-
•
col (RIP) broadcasts to advertise its routing tables to other routers on your network. You
may choose from the following protocols:
• RIP-1: Routing Information Protocol version 1
• RIP-2: RIP Version 2 is an extension of the original Routing Information Protocol (RIP-
1) that expands the amount of useful information in the RIP packets. While RIP-1 and
RIP-2 share the same basic algorithms, RIP-2 supports several new features, including
inclusion of subnet masks in RIP packets and implementation of multicasting instead of
broadcasting (which reduces the load on hosts which do not support routing protocols.
• RIP-1 compatibility: Compatible with RIP version 1
• RIP-2 with MD5: MD5 authentication is an extension of RIP-2 that increases security
by requiring an authentication key when routes are advertised.
• RIP MD5 Key: Secret password when using RIP-2 with MD5.
• RIP Receive Mode: Specifies whether the Gateway should use Routing Information
Protocol (RIP) broadcasts to update its routing tables with information received from
other routers on your network. The protocol choices are the same as for the RIP send
mode.
Proxy ARP: Specifies whether you want the Gateway to respond when it receives an
•
address resolution protocol for devices behind it. This is a way to make a computer that
is physically located on one network appear to be part of a different physical network
connected to the same Gateway. It allows you to hide a computer with a public IP
address on a private network behind your Gateway, and still have the computer appear
to be on the public network "in front of" the Gateway.
