ZyWALL 2 Plus User’s Guide

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. 

"

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 > LAN > 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 DMZ Port Roles and WLAN Port 
Roles screens.
