Ive not had this issue on my 360 or Xone until Destiny, which despite my xbox one saying open, is strict. What's the deal with this? Ive tried port forwarding to no avail. Static ip address also. I'm not in a situation where this shouldn't b fixable but is now ruining raids due to chat in game issues and party chat being ruined in the last patch. The bungie nat help is appalling vague as well but have done everything suggested. Would be nice to get some decent proper advice from someone on this please as seems to be a known issue!?
