ZyWALL VPN is an ideal cost-effective way to securely connect branch offices, business
partners and telecommuters over the Internet without the need (and expense) for leased lines
between sites.

1.3.3 3G WAN Application (ZyWALL 5 Only)
Insert a 3G card to have the ZyWALL (in router mode) wirelessly access the Internet via a 3G
base station.
At the time of writing, only ZyWALL 5 supports 3G, so all 3G descriptions
relate to ZyWALL 5 only. See
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.
