This is retarded. There is no logical reason to do this. Yes Windows can funcation as a router with RRAS but this situation does not warrant it. By having ALL data on the network flow through a Windows box you are serverely limiting your network. By a SWITCH and have it do its job and packet switch for you, it is what it was DESIGNED to do. It will also make the network much more manageable. BTW ever heard of KISS?
