Okay, so I've asked several people what to do and get the same answer, my NAT setting keeps changing from moderate, to strict, to open than back to strict. It's been doing this for a couple of weeks now, and it's driving me CRAZY! I've done everything! Is there anything else I can do? If you want to help that's great! pm me, and I'll send you an ss of my router screen and you can take me step by step of what I need to do. Any and all help is greatly needed. Thanks!
