i have just set up a small network at my house that consists of two computers and a router(the router is connected to my cable modem). Im dont why but i can no longer connect to other computers through ip and when i look at my ip using the ipconfig command, it is different from the ip i get on a website such as www.whatismyip.com... why? i realized this because i tried to play a game of AoE with my friend and he couldnt find my game using either ip address. He has the same problem(he's behind a hub), and i couldnt connect to a game that he was hosting either. If i try to have a direct connection on AIM it fails, nobody outside my home network can even ping me. If i unplug from the router and plug directly into the cable modem, i can host games, people can ping me, etc. but then my dad doesnt have internet access...
Can anybody tell me why this happens and how i can have people connect to me while im behind this router?(and how i can connect to my friend if i he hosts the game?)
