Determine your Port Number and Type
To change your NAT type to “open,” you need to input the port number and type of your game. To find your game’s port number, navigate to your game’s network settings and look for the number listed under “Inbound port.” Here are the inbound ports and types for some of the most popular PC games:
TCP: 5222, 5795-5847
Call of Duty: Black Ops 4
UDP: 5222, 5795-5847
TCP: 3074, 27014-27050
UDP: 3478, 4379-4380, 27000-27031, 27036
TCP: 5222, 9988, 17502, 20000-20100, 22990, 42127
UDP: 3659, 14000-14016, 22990-23006, 25200-25300
Change your NAT type
To change your NAT type to “open” with port forwarding, return to your router’s setup page.
1. On your router’s setup page, navigate to “port forwarding.” Every router manufacturer arranges the setup page in a slightly different way. Here’s how to find the port-forwarding panel on a Linksys router.
2. When you make it to the panel, a list of ports should pop up. Enable a new port and give it a name in the “Description” box.
Enter the inbound port number of your game and the type of port. See “Determine your port number and type” above.
Under “Private port” enter the same number you entered under “Inbound port” i.e. the one indicated in your game’s network settings.
Save your settings.
6. Unplug your console for 30 seconds. Then, reboot it. Your router and game settings should now indicate that your NAT is open.
For more in-depth information about switching between “strict,” “moderate,” and “open” ports, we suggest visiting your router manufacturer’s official website.
Port Triggering for Multiple Gaming Consoles
To change your console’s NAT type to “open,” you can use either port forwarding or port triggering. If you have multiple gaming consoles on the same server, you’ll want to set up port triggering instead of port forwarding. You can set up port triggering on your router’s setup page. Just navigate to “port triggering” instead of “port forwarding” from the main menu.
