connecting two 2600 series routers

[mrfroggigger]

what i have are 2 routers, one in which i own (bought) and one that was provided to me by my internet provider when i upgraded my internet connection, the problem that i'm having is the one that i own handles all of my company communication, right now, the reason for the upgrade was to remove all the isdn in the outer offices and replace it with dsl and do a vpn through that. i'm not going to take down all the offices at once i'm doing them in phases, so therefore i will still need the router that i own so my outer offices can connect to the main office, but i also need utilize the new router for vpn. my question i would say is, could i do a ip route for all traffic coming to the old router and route it to the new router for internet purposes only ?? if not suggestions as to what/could do. any help is much appreciated. i have attached my running config of my old router

not too sure if I quite understand, however old router can be configured to use new router as gateway, you would therefore have to redirect all traffic from old router to new router using IP route command to specific interface that connects both routers. If u are not intending to change any stuff Like IP adress on your lan, and these should ofcourse differ from those provided by your ISP, then run NAT on the old router. Hope this helps...
