My Problem: Can't join friends on xbox live
I can connect to Xbox live without any connection problems. I can play online matches without any problems. HOWEVER, when I try to connect with a friend (e.g. to join a party or join a game invite), it does not let me.
I've googled this issue and all the results say that this is a NAT problem. I am supposed to "make my NAT connection be "open" instead of "moderate"/"strict""
Can anyone help me do this? I tried changing some things on my router but with no luck. Also on the Microsoft website it said that if I enable UPnP, that it should solve the problem. I have a "D-Link DI-624" router and have no idea how to do any of this.
Can anyone help me out? Some step by step solution possibly? I'd really appreciate the help..
