You need a Router with two WAN ports! On a router I would configure two Static Routes one default router for the main DSL and one for the backup DSL that is weighted to a lower priority. This is known as surprisingly Weighted Static Routes.
I currently have two separated routers for two DSLs, which are in different ISPs.
Maybe I can setup a debian box for acting as that router? Thanks Yong
