I've got a Windows Vista with a wireless router, while he has Windows XP with a modem.
I hear you need to open ports? I know nothing of these ports...I've tried opening them as exceptions on my Windows Firewall, but Port checks say they're closed. It's all too confusing, it makes my head boil!!
I'm probably gonna have to have my hand held through this process...I know nothing about any of this. Any help would be greatly appreciated...If there's any other info needed, I'll see what I can dig up...
