Use the Port Roles screen to set ports as LAN, DMZ or WLAN interfaces. The LAN port role 
is not available on all models.

Connect wireless LAN Access Points (APs) to WLAN interfaces to extend the ZyWALL’s 
wireless LAN coverage. The WLAN port role allows the ZyWALL’s firewall to treat traffic 
from connected APs as part of the ZyWALL’s WLAN. You can specify firewall rules for 
traffic going to or from the WLAN. The WLAN includes the ZyWALL’s own WLAN and the 
Ethernet ports in the WLAN port role.  

The following figure shows the ZyWALL with a wireless card installed and an AP connected 
to an Ethernet port in the WLAN port role.
