Hi all. My NAT on my Xbox One shows it is opened. Sometimes it changes to moderate. When I play Call Of Duty Advanced Warfare or Destiny, they state that my NAT is strict. When I play Call Of Duty AW, It takes longer than usual to get into a game. When I connect, there are times I get lag free games and times when the game is laggy/unplayable. When I play Destiny, it says that I have a network issue. I can still connect to games faster than Call Of Duty and the performance is better. I do not have any connection issues with Titanfall, D&D Neverwinter Nights, and Diablo 3. I read about how to open the NAT. It sounds complicated. This NAT issue occurred after Memorial Day. My question is will the NAT effect my multiplayer gameplay? Can a strict or moderate NAT cause lag? I am not interested in hosting games or communicating to other players. I just want to join the games and play them. Like I said. I didn't experience any problems before Memorial Day. Thank you for taking the time to read my post!
