The ZyWALL automatically balances the traffic load amongst the available WAN
connections. This enhances overall network throughput. Plus, if a WAN connection goes
down, the ZyWALL 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.
To fine-tune the load balancing configuration, see Chapter 11 on page 269. See also Section
6.6 on page 154 for an example.
6.3 How to Set Up a WLAN Interface
You can install a wireless LAN card (IEEE 802.11b/g) in the PCIMCIA slot (see Table 267 on
page 749 for the supported cards). 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.
6.3.1 How to Set Up User Accounts
The ZyWALL 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.
