Although the way in which to check your current NAT type differs depending on what platform you’re playing on, the most effective way of resolving the issue is the same for each. What you’ll want to do is the following:

  • Access the admin page for your router. Details on how to do so should be printed on the back of your router unit.
  • When prompted for a username and password, input the credentials included on the same label as before. You should now be logged in to the admin page associated with your router.
  • From here, you’ll want to enable UPnP, or Universal Plug and Play. This setting should be immediately visible from the home page, or be contained within a backlink to a “media” page.
  • Turn on UPnP. You can now assign your NAT type to your router’s associated DMZ, or Demilitarized Zone. It’s important to note that this can potentially increase the risk of security threats, though. For a safer way to change your NAT type, consider port forwarding.
  • For port forwarding information, you’ll need to visit the specific page for port forwarding associated with your specific router, as the process varies depending and its make and model.
  • After following this information, consult the recommended port forwarding values for your platform of choice. Sony and Microsoft both recommend different sets of ports, which you can easily find with a quick Google search.
  • The former option, which is to assign your NAT type to its associated DMZ, will give you an Open NAT type. The latter option, which is port forwarding, will give you a Moderate one.
