The following table describes the fields in this screen.

	Table 5-3 IP Alias
LABEL	DESCRIPTION
IP Alias 1,2	Select the check box to configure another LAN for the ZyWALL.
IP Address	Enter the IP address of your ZyWALL in dotted decimal notation.
IP Subnet Mask	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.
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-2Band RIP-2Msends the routing data in RIP-2 format; the difference being that
	RIP-2Buses subnet broadcasting while RIP-2Muses 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.
