LABEL
RIP Direction 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.
RIP Version 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.

Configuring Port Roles

To configure a LAN/DMZ port as a LAN or DMZ port, select its radio button next to LAN or DMZ
and click Apply. Otherwise, click Reset to restore the previous configuration. The radio buttons
correspond to Ethernet ports on the front panel of the ZyWALL. By default, ports 1 to 4 are all LAN
ports.
Do the following if you are configuring from a computer
connected to a LAN or DMZ port and changing the port's role:
1. Make sure your computer's IP address is in the same subnet as the
2. A port's IP address varies as its role changes, use the appropriate
Click LAN, then Port Roles. The screen appears as shown.
