Arris (Modems/Gateways): nat type
Hi SquareAcorn824,

Thanks for reaching out to us today. If you're receiving a NAT warning when you connect to Xbox Live, see the
Xbox One Multiplayer Game Solution. To
let your Xbox One console communicate with Xbox Live, you might have to open or forward ports, which means you'll be making a configuration change to your firewall or network hardware, such as a router. (this will make your NAT open)

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)

You can 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.

:)
