The following table describes the labels in this screen.
10.4 WLAN IP Alias
IP alias allows you to partition a physical network into different logical networks over the
same Ethernet interface.
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).
" 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.
Table 44 NETWORK > WLAN > Static DHCP
