Wireless fail over

could someone point me in the direction of setting up my RB411U as internet fail over.

I have a DSL / RB750 as my main router/internet connection. Then I have a RB411U with a 3G USB Modem. The DSL is not always that stable here and I need to set up a solution, so I have a backup in case the DSL goes down to keep up a basic internet connection.

The preferred solution would be that that the 3G modem only connects when the DSL is down.

You could start in the wiki. Here is a script that changes the gateway on main gateway failure (and back):

Thanks SurferTim. I will try to test it and see if I can make it work.

Any ideas how I can setup the 411 so that it will dial in, when the gateway is switched?
