[Ragnarok]

Hmmm..... I was wondering if any of ya'll could help me out here. Me and my bro just bought SE4 Gold and we live an hour apart, so we wanted to start a IP game. But when we set everything up just like the book and stuff says to do it won't let either one of us connect to the host. I tried being host and it wouldn't let him connect, then he tried being host and same thing happened. Do any of you know what's happening here? But when I tried the game between my computer and my parents computer it worked just fine through IP connection. What's wrong? If any of you could help I'd be thankful!
