Insert a 3G card to have the ZyWALL (in router mode) wirelessly access the Internet via a 3G
base station. See
Section 8.12 on page 152 for more information about 3G.
With both the primary WAN (physical WAN port) and 3G WAN connections enabled, you
can use load balancing to improve quality of service and maximize bandwidth utilization or set
one of the WAN connections as a backup.
