SB 107 in bridge mode

[FredDenHeijer]

Is there anyone who can tell me how to set an SB107 router in to bridge mode.

I have an ASA who is already connected to anohter internet connection and want to set the line of the SB107 as an backup connection for redundancy. I've tried several configs but i don't succeed to get this connection running.

Before configuring the DSL router for bridge mode ensure that you have clear all the existing configuration. It may be a Layer2 issue.Ensure that your bridge port is in forwarding state. For your Cisco DSL Router to forward packets to your ISP, your bridged interface must be in a forwarding state. If your bridged interface is in a blocking state, there is a loop in your network that you have to remove before you are able to pass traffic. The most common cause of a loop in a DSL network is to have two bridged DSL circuits to the same ISP.
