6.2 How to Configure a Cellular Interface
Use 3G cards for cellular WAN (Internet) connections. You can have up to three simultaneous
3G connections (one 3G device in the ZyWALL’s PCIMCIA slot and one connected to each
of the ZyWALL’s two USB ports). Table 267 on page 749 lists the compatible 3G devices. In
this example you install or connect the 3G card before you configure the cellular interfaces but
is also possible to reverse the sequence.
1 Make sure the 3G device’s SIM card is installed.
2 Install the 3G device in the ZyWALL’s PCIMCIA slot or connect it to one of the
ZyWALL’s USB ports.
3 Click Network > Interface > Cellular. Click the 3G card’s Edit icon.

4 It is highly recommended that you set the Zone to WAN to apply your WAN zone
security settings to this 3G connection. Leaving Zone blank has the ZyWALL not apply
any security settings to the 3G connection. Enter the PIN Code provided by the cellular
3G service provider (0000 in this example).
In Related Setting, keep Add this interface to Trunk to allow WAN load balance
selected. Click OK.
