DESCRIPTION
Type the IP address of your ZyWALL's DMZ port in dotted decimal notation.
Note: Make sure the IP addresses of the LAN, WAN and DMZ are
on separate subnets.
The subnet mask specifies the network number portion of an IP address. Your
ZyWALL 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 ZyWALL 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 ZyWALL 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 ZyWALL 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.
