Multi-player games that are played online require an open NAT type to operate correctly.  If you are playing on a restricted, or strict NAT type, you may encounter the following issues:

  • Inability to join online games
  • Inability to host online games
  • Unable to communicate with other players in-game or via the console party chat

Although NAT Type open looks like the best option, it can leave you open to security risks, so the optimal setting would be Moderate/Type 2.
