Additional Network Ports for Multiplayer Gaming: Xbox Unknown Error

Ports required to use Xbox Live

These ports must be open for Xbox Live to work:

• Port 88 (UDP)
• Port 3074 (UDP and TCP)
• Port 53 (UDP and TCP)
• Port 80 (TCP)
• Port 500 (UDP)
• Port 3544 (UDP)
• Port 4500 (UDP)

Note Some game developers require you to open additional ports. You should always check the game developer's website to see if the game you're playing needs additional ports to work. We've gathered some ports you might need
and have added them to the
Additional Network Ports for Multiplayer Gaming forum.

If you're connected to a network through your workplace or school, ask the network administrator to open these ports.

If you receive a NAT warning when you connect to Xbox Live, see the

It’s a bit of a pain if you don’t know what you’re doing but it’s simple enough 👍

Hi I Rundis33! The official list of Xbox One ports is:

• Port 88 (UDP)
• Port 3074 (UDP and TCP)
• Port 53 (UDP and TCP)
• Port 80 (TCP)
• Port 500 (UDP)
• UDP Port 3544 (UDP)
• UDP Port 4500 (UDP)

I would also strongly suggest forwarding UDP and TCP ports 3075 and 3076, as these are used by a number of multiplayer games (especially Activision games like Call of Duty.) If you don't forward those, although your Xbox itself will have an Open NAT, when
you go to the multiplayer menu in-game, you will see a message saying your NAT is Moderate until you forward those developer-specific ports.

Though too many to list here, each game may have its own port that needs to be forwarded - I know EA games like Titanfall and Battlefront have ports listed, though I have had success with Open NAT by only using the Titanfall ports and NOT the Battlefront
ports - it results in a conflict, somehow, which slows down the entire system.

Likewise, Ubisoft's The Crew has a specific port which needs to be forwarded - if you have a Moderate NAT in-game, there is a button to press which tells you what to check to make sure you have the right port. I had this happen to me, forwarded the port
suggested by the game, and my NAT was immediately Open in-game.

So, unfortunately it's not a strict black-and-white answer, but the ports listed above will give you the start that you need! You'll have to play it by ear from there if you have issues with specific games. Hope this helps!
