Landonio1 got a reaction from Netduma Admin in Seriously about to pull my hair out here. Please help.
I had UPnP enabled. I have since I first got the router. I just decided to turn it off and try port forwarding because I was out of options. It wasn't opening the Teredo port for some reason though. No matter what I did, I could not get the damn thing open, until I changed the port used within the Xbox.
