74 Chapter 4 LAN Screens
4.3 LAN TCP/IP
The ZyWALL has built-in DHCP server capability that assigns IP addresses and DNS servers
to systems that support DHCP client capability.
4.3.1 Factory LAN Defaults
The LAN parameters of the ZyWALL are preset in the factory with the following values:
• IP address of 192.168.167.1 with subnet mask of 255.255.255.0.
• DHCP server enabled with one client IP address of 192.168.167.33.
These parameters should work for the majority of installations. If your ISP gives you explicit
DNS server address(es), read the embedded web configurator help regarding what fields need
to be configured.
4.3.2 IP Address and Subnet Mask
Refer to Section 3.2.2.2 on page 52 for this information.
4.3.3 RIP Setup
RIP (Routing Information Protocol, RFC 1058 and RFC 1389) allows a router to exchange
routing information with other routers.
RIP Direction controls the sending and receiving of
RIP packets. 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 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 send 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 RIP Version to RIP-1 .
