Hello, I have two broadband services coming into my building; will call them north and south, Each service has a linksys super G router attached. I want to be able to allow either router to act as a DHCP server. Currently both services are running and connectivity to the Internet is good-to-go. Router south has a switch which services my 2003 domain controller and other clients. Router north has a switch attached serving more clients. I need help figuring out how to connect the two networks together so that clients served by the north router can touch resources served by the south router, Any help would be great!
