Networking, Subnets and Basic Routing - Please Explain?
I have been having trouble setting up my router so that it knows about a network behind another one my routers (serving up another subnet). I understand a little of how to configure the routing tables but I was wondering if someone could just explain the basics of how an ip network (subnets/subnet masks etc) works, as it is still a little mysterious to me (it's amazing that I have been able to get things working with my limited knowledge). I mean how does one computer talk to another on the same subnet or across the world (what is the difference between a mac address and an IP address), what is going on behind the scenes??? I don't mind technical speak as long as it's logically ordered. Thanks so much!
