I can't find any information about the new Ports for connecting to Xbox live.

Have you done port fort forwarding on your router?

Network ports used by Xbox Live on Xbox One

A network port lets your Xbox One console communicate with the Xbox Live servers and other Xbox One consoles over the internet.
To let your Xbox One console communicate with Xbox Live, you might need to open or forward ports, which means you'll be making a configuration change to your firewall or network hardware, such as a router. Port forwarding for Xbox One is done on
your router or other network hardware, not on the Xbox console itself.

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.

You can also find information about opening ports on your router at the Port Forward website. This website lists commonly used ports for various apps and games, but if your
router isn't listed or you need more help, contact your internet service provider or router manufacturer.

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 Xbox One Multiplayer Game Solution.

But I can't find any source for ports used by iOS version of the App, sorry.

Hey JBett25!

Yes, you can either have UPnP on your router enabled or do the manual port forwarding. I would suggest using manual port forwarding as it is more reliable.

Hi Sergeant Dill,

A firewall is always a good idea, but there are certain ports that Xbox Live uses that should be forwarded to ensure better performance.

You can find more information about what ports to forward and how to do that
