I have a LinkSys RV042 Dual Wan Router in my office. I am using it in smartlink mode, so that when primary fails, the backup link takes over.

The problem is that backup link is highly under-utilized. I have a dev machine that periodically replicates data from a production server. I would like to route all of this dev's machine's traffic through the backup link. Is it possible?

If you put the RV042 in Load Balancing mode, you can set it to send traffic from an IP address or service over a specific WAN interface. You can find more details in this Cisco support doc (you might need to register before you can view it)

I've never done this before but why don't you see if you can setup a dedicated rounte from the dev machine to the net using a custom route? I've done custom routing for VPN issues, but never trying to force a machine out a specific WAN put.

In the RV042, select Setup, then Advanced Routing, you should be able to add a route for the dev machine to the backup WAN port/IP.
