sure you have a compatible mobile broadband device installed or connected. Go to http://
www.zyxel.com/support/download_landing.shtml and see the 3G Dongle Document to check the
compatible mobile broadband devices. Also, make sure the cellular interface is enabled and the
cellular interface has the correct user name, password, and PIN code configured with the correct
casing.
1.3 How to Configure Two Different WAN Interfaces with
Different IP Addresses in the Same VLAN
This is an example of using ZyWALL/USG to configure two different WAN interfaces with different IP
addresses in the same VLAN. After configuration, you can have the same VLAN ID for two different
WAN interfaces.

VLAN Example
Note: This example requires the ZyWALL/USG models which can apply port grouping.
All network IP addresses and subnet masks are used as examples in this article.
Please replace them with your actual network IP addresses and subnet masks. This
example was tested using ZyWALL USG300 (Firmware Version: ZLD 3.30).
