Problem: My NAT says it's open, but I cannot invite other people to my Live or Halo party.
I've searched for the term status not joinable and found only the official complaint thread. I've heard that you can change your router's settings to fix that though. Any word on how I can do that? Anyone that has done so? If there's a way to be proactive in my Halo experience instead of complaining about it.
Thanks!
