This way the ZyWALL can automatically balance the traffic load amongst the available WAN
connections to enhance overall network throughput. Plus, if a WAN connection goes down, the
ZyWALL still sends traffic through the remaining WAN connections. For a simple test, disconnect all
of the ZyWALL’s wired WAN connections. If you can still access the Internet, your cellular interface
is properly configured and your cellular device is working.
2.4 How to Set Up a Wireless LAN
This tutorial applies only to models that include wireless LAN.
You can configure different interfaces to use on the wireless LAN card. This lets you have different
wireless LAN networks using different SSIDs. You can configure the WLAN interfaces before or after
you install the wireless LAN card. This example shows how to create a WLAN interface that uses
WPA or WPA2 security and the ZyWALL’s local user database for authentication.
2.4.1 Set Up User Accounts
Besides WPA-PSK, the ZyWALL also supports TTLS using PAP so you can use the ZyWALL’s local
user database with WPA or WPA2 instead of needing an external RADIUS server. For each WLAN
user, set up a user account containing the user name and password the WLAN user needs to enter
to connect to the wireless LAN.
1 Click Configuration > Object > User/Group > User and the Add icon.
2 Set the User Name to wlan_user. Enter (and re-enter) the user’s password. Click OK.
3 Use the Add icon in the Configuration > Object > User/Group > User screen to set up the
remaining user accounts in similar fashion.
2.4.2 Create the WLAN Interface
1 Click Configuration > Network > Interface > WLAN > Add to open the WLAN Add screen.
