1.2 How to Configure the 3G/LTE Interface on the ZyWALL/
USG as a WAN Backup
This is an example of using ZyWALL/USG to configure 3G/LTE interface as a WAN backup that
ensures the ZyWALL/USG provides the continuously Internet connections when the primary WAN
interface is down. After configuration, it can provide additional mobile broadband WAN connectivity
or a redundant link for maximum reliability.
Figure 17 ZyWALL/USG with 3G/LTE Interface as a WAN Backup Example
Note: This example includes weighted load balancing (Weighted Round Robin) so that
most of your Internet traffic is handled by ISP connected to wan1 before it fails
over to 3G/LTE.
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 USG310 (Firmware Version: ZLD 4.13).
