194 Chapter 10 Wireless LAN
The ZyWALL has a single WLAN interface. Even though more than one of ports 1~4 may be
in the WLAN port role, they are all still part of a single physical Ethernet interface and all use
the same IP address.
The ZyWALL supports three logical WLAN interfaces via its single physical WLAN Ethernet
interface. The ZyWALL itself is the gateway for each of the logical WLAN networks.
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 > IP Alias. The
screen appears as shown.
