How to configure CloudGate to switch automatically to WWAN when the fixed DSL connection is offline?

This is how it works:

1. Click on the ‘Move up/down’ arrows to set the ‘Main ethernet’ interface as the #1 interface the CloudGate uses to connect to the internet. (See screenshot above)

2. Click on the ‘Move up/down’ arrows to set the ‘3G Connection’ interface as the #2 interface the CloudGate uses to connect to the internet. (See screenshot above)

3. Make sure the CloudGate is connected via fixed DSL line.

4. Reboot the CloudGate. (this will cause the 'Main Ethernet' interface to act as a WAN interface instead of a LAN interface)

5. The main Ethernet port will act as a WAN interface and the CloudGate will receive an IP address from the fixed DSL network DHCP server automatically.

6. Once the fixed DSL line’s internet connection is lost, the CloudGate will automatically connect to the 3G network for as long as the fixed DSL connection is offline.

7. When the fixed DSL connection is back online, all traffic will be routed through the ‘Main Ethernet’ interface once again.
