Okay so before, a couple months ago, I could connect with all my friends. Now, I can't. 3/4 of my friends on my friends list I can't connect to, can't play games, or join their parties. I've been looking up why this is happening, NAT is the reason I kept on getting. Yes, I do have a moderate NAT, I've had it for the past 4 years and yes, I've tried EVERYTHING to fix it. Nothing works though! I called my ISP and they don't even know what NAT is!! Strangest thing too, all of my friends have the same ISP as me. I'm running out of options, what can I do!?
