I setup windows 2003 as a router using RRAS to route 2 class C subnets together. I have a problem that I can access computers on my existing network from my new network computers, but can not access my new network from existing network. (ping, file sharing, remote desktop…. Etc) On Win03 which hosts RRAS, it can access both existing and new networks. I try to match gateway from both, but it still does not work. Please advise.
