When you use IP alias, you can also configure firewall rules to control access between the
WLAN's logical networks (subnets).
Note: Make sure that the subnets of the logical networks do not overlap.
To change your ZyWALL’s IP alias settings, click NETWORK, WLAN and then the IP Alias
tab. The screen appears as shown.

IP Address Enter the IP address of your ZyWALL in dotted decimal notation.
Alternatively, click the right mouse button to copy and/or paste the IP address.
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, RFC 1058 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.
