Set up DHCP reservation on your router (if available). DHCP reservation is not available on all routers. If it is available on your router, you will need to log in to your router's user interface and locate the DHCP reservation settings and add your Xbox One's MAC address. Consult your router's user's manual or manufacturer's web page to learn how to set up DHCP reservation. Use the following steps to find the MAC address on your Xbox One:[3]

Press the Xbox button on your controller.

Select Profile & system.

Select Settings.

Select Network.

Select Advanced Settings

Note your Wireless MAC address.

Get your network information. If your router does not allow you to enable DCHP reservation, you will need to set up port forwarding on your router. Before you can do that, you need to get some information about your network. You need to find out your computer's primary IP address, subnet mask, default gateway, primary and secondary (if available) DNS server. Use the following steps to find that information on your computer:

Windows: Click the Windows Start menu and type "cmd". Open the Command Prompt. Then type "ipconfig" and press Enter. Locate the information for your wireless network adapter. Write down the information needed.

Mac: Click the Apple Icon in the menu bar and click System Preferences. Click Network and click the Advanced button. Click the TCP/IP tab and write down the information needed.

Enable Teredo and/or IPv6 Tunneling. If you are still having NAT connection problems with your Xbox One, log in to your router's user interface and check for the option to enable Teredo Tunneling, and/or IPv6 Tunneling. Enable this option and save your router's settings. Restart your router and check your connection status on your Xbox One.

Log in to your router's user interface. Any further troubleshooting will need to be done on your router's user interface. To open your router's user interface, open a web browser on your computer and enter your router's local IP address in the address bar. Then you will need to enter the administrator's username and password to log in. You can find all this information in your router's user manual or on the manufacturer's web page.

Common local IP addresses used to open your router's user interface include: "192.168.0.1," "192.168.1.1," "192.168.2.1," "192.168.8", and "10.0.0.1"

Common administrator usernames and passwords include: "admin," "12345", or simply left blank.

Your router may have a sticker on the back or bottom that instructions on how to log in to the user interface. This should contain the local IP address as well as the default username and password.

Add port forwarding to your router. If you are still having NAT connection issues on your Xbox One, there may be a firewall on your router. If you are on a school or work network, you'll need to contact the administrator. If you have your own personal router, you will need to use port forwarding on your router and make sure your Xbox One's MAC address and unique IP address are able to access the following ports:[4]

Port 88 (UDP)

Port 3074 (UDP and TCP)

Port 53 (UDP and TCP)

Port 80 (TCP

Port 500 (UDP)

Port 3544 (UDP)

Port UDP 4500 (UDP
