10.5 WLAN Port Roles
Use the Port Roles screen to set ports as part of the LAN, DMZ and/or WLAN interface.
Ports 1~4 on the ZyWALL can be part of the LAN, DMZ or WLAN interface.
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 Ethernet ports in the WLAN port
role.
The following figure shows the ZyWALL with an AP connected to an Ethernet port in the
WLAN port role.

" Do the following if you are configuring from a computer connected to a LAN,
DMZ or WLAN port and changing the port's role:
1 A port's IP address varies as its role changes, make sure your computer's IP address is in
the same subnet as the ZyWALL's LAN, DMZ or WLAN IP address.
2 Use the appropriate LAN, DMZ or WLAN IP address to access the ZyWALL.
To change your ZyWALL’s port role settings, click NETWORK > WLAN > Port Roles. The
screen appears as shown.
The radio buttons correspond to Ethernet ports on the front panel of the ZyWALL. On the
ZyWALL, ports 1 to 4 are all LAN ports by default.
" Your changes are also reflected in the LAN and DMZ Port Roles screen.
