DESCRIPTION
Type the IP address of your Prestige's DMZ port in dotted decimal notation. Make
sure the IP address is on a separate subnet from the LAN port.
The subnet mask specifies the network number portion of an IP address. Your
Prestige will automatically calculate the subnet mask based on the IP address
that you assign. Unless you are implementing subnetting, use the subnet mask
computed by the Prestige 255.255.255.0.
RIP (Routing Information Protocol, RFC1058 and RFC 1389) allows a router to
exchange routing information with other routers. The RIP Direction field controls
the sending and receiving of RIP packets. Select the RIP direction from Both/In
Only/Out Only/None. When set to Both or Out Only, the Prestige will broadcast
its routing table periodically. When set to Both or In Only, it will incorporate the
RIP information that it receives; when set to None, it will not send any RIP
packets and will ignore any RIP packets received. Both is the default.
The RIP Version field controls the format and the broadcasting method of the
RIP packets that the Prestige sends (it recognizes both formats when receiving).
RIP-1 is universally supported but RIP-2 carries more information. RIP-1 is
probably adequate for most networks, unless you have an unusual network
topology. Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the
difference being that RIP-2B uses subnet broadcasting while RIP-2M uses
multicasting. Multicasting can reduce the load on non-router machines since they
generally do not listen to the RIP multicast address and so will not receive the
RIP packets. However, if one router uses multicasting, then all routers on your
network must use multicasting, also. By default, RIP direction is set to Both and
the Version set to RIP-1.
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to
establish membership in a multicast group. The Prestige supports both IGMP
version 1 (IGMP-v1) and IGMP-v2. Select None to disable it.
