I've got a bit of a weird situation.
4 friends. A, B, C, D.
A, B, & C can connect to D
C & D can connect to each other
A & B cannot connect to C
C & D cannot connect to A or B
Confusing, sorry. Basically we're all running the same version (no beta) and are pretty close to each other. We can all join the same dedicated server in the MP menu and play together, but if I try to connect to anyone but one of my friends I will get connection failed. I can connect to one friend, but he can't connect to games I host.
I've forwarded the 2302 port that we all play one. The guy that I connect to has done nothing with regards to forwarding/firewalls/AV programs and yet I can still connect to him but not vice versa.
So yeah idk how to figure out what the problem is as I'm not very good with this sort of stuff. I've forwarded ports and uPNP and turned off my firewalls/AV and still nobody can connect to me.
Any advice would be great as it'd mean I won't have to join 280ping servers to play the maps I like with friends.
