This a response to a previous reply in hopes to aid successful operation :)
You should be able to do what you're after by adding static routes for the VPN endpoint and for anything you need to locate that (e.g. DNS servers if you need them) over your normal internet connection, and then changing the default route to the IP address of a router on the remote network.
I thought with bridging you did not need to create any extra routes..... Isn't that the point of a bridge, or am i wrong. Please read here http://openvpn.net/howto.html#scope and http://openvpn.net/bridge.html Anyway Good Luck with your OpenVPN Bridging Ventures!
