So I've been having some issues lately, can't play with certain people on the xbox 360.
According to my router settings the NAT is open and I just recently figured out how to forward all the ports for xbox live.
I didn't take the time to do that before because I had not really had any issues up to this point.
So now with the standard ports forwarded for connections and even some additional for specific online games I could find I still can't connect to certain players on the 360.
The weird part is on the xbox one my connectivity seems to be much better.

I play both consoles on wireless I wasn't expecting top results but definitely didn't expect being unable to play with certain people.
Like I said, hasn't really been an issue up to this point.
They often respond telling me that their NAT is also open, so what gives? Routers go bad I hear?

What kind of setups do you guys have, does it make a huge difference?

Wouldn't mind hearing from the PC guys either, it seems pretty similar but if it isn't let me know haha.
