ZyWALL 5/35/70 Series User’s Guide

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.
