there are only two ways i know to maintain routing on incomming traffic, first being to have your DSL and T1 from the same company and they can set up your links with routing on there side that will reflect your fail over situation, the second way is to multihome with and AS and run BGP, so if you have any sort of IP specific traffic such as running servers at your location you will have to do one of the above option, however if this is just for a office connection to allow your employees to check myspace and play poker, then you can do it much easier, would be as simple as running and internal routing protocal -- -Lawrence
