connection to access the Internet.

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.

6.3 How to Configure Load Balancing

This example shows how to configure a trunk for two WAN connections (to the
Internet). The available bandwidth for the connections is 1Mbps (ge2) and 512
Kbps (ge3) respectively. As these connections have different bandwidth, use the
Weighted Round Robin algorithm to send traffic to wan1 and wan2 in a 2:1
ratio.
Figure 47 Trunk Example
You do not have to change many of the ZyWALL's settings from the defaults to set
up this trunk. You only have to set up the outgoing bandwidth on each of the WAN
interfaces and configure the WAN_TRUNK trunk's load balancing settings.
