LABEL DESCRIPTION
LAN TCP/IP
IP Address Type the IP address of your ZyWALL in dotted decimal notation. 192.168.1.1 is the
factory default. Alternatively, click the right mouse button to copy and/or paste the
IP address.
IP Subnet Mask The subnet mask specifies the network number portion of an IP address. Your
ZyWALL automatically calculates the subnet mask based on the IP address that
you assign. Unless you are implementing subnetting, use the subnet mask
computed by the ZyWALL.
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. Both is the default.
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.
