Currently I have a setup that involves connections from several different providers ranging from 6 mbit DSL's to 10 mbit fractional DS3 connections tied together to provide multipath high availability internet in our area for schools and businesses. We recently extended our coverage to another area which has several other ISP's. The box that is doing multiwan right now is the only gateway for the entire network and for some sites it is several hops back to that gateway. My goal is for us to purchase bandwidth in other locations, install a linux box and have multiple gateways available, but I think this is easier said than done. I will diagram this as best I can for you in current and future setup modes.

My goal is for people in area 1-4 to all be able to use any of the connections to ISP 1-z and if one fails it passes the traffic through the network to an available route. Area 1-4 don't current have any linux hardware but it has been a long standing plan to put some in place in those areas as well so if that is required it could be done. These areas are all serviced by different small ISP's and would make acceptable alternate routes say if a backhual failed for some reason so that is the goal.
Thanks for any input.
