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
Xbox One Multiplayer Game Solution

Hi, my name is Marvina and I will be happy to help you.

I'm sorry you have this problem, researching on the internet I was able to find that in the forum, the independent advisor Andersonpasos, recommends the following steps for a solution.

Possibly it's your NAT

What is NAT?

NAT is nothing more than a protocol that translates IP addresses and TCP ports from the local network to the Internet. That is, the packet to be sent or received from your workstation on your local network goes to the server where your IP is exchanged for the IP of the server and the replacement of the IP of the local network validates the sending of the packet on the Internet. . When returning the package the same thing happens, but in reverse. Which ensures that the package reaches its destination.

Why is NAT important?
Your NAT type, combined with the NAT type of other players, determines whether you can use multiplayer games or group chats successfully. The following tables illustrate the differences between NAT types. And depending on your NAT type, who you can play multiplayer games with and who you can listen to in a group chat.

OPEN NAT

You can chat with other people, as well as host and play multiplayer games with people who have some type of NAT on the network.

MODERATE NAT

You can chat and participate in multiplayer games with some people; However, you may not listen to or play with others and you probably won't be chosen to host a match.

STRICT NAT
You can chat and play multiplayer games with people who have an OPEN NAT type. You cannot be chosen to organize a match.

NAT AVAILABLE

You won't be able to use group chat or connect to multiplayer games on some Xbox Live titles.
On your Windows 10 you can:

Change DNS:

Click Control Panel > Network and Internet > Network and Sharing Center;
In the Network and Sharing Center, click Change adapter settings;
Now right click on Ethernet and select Properties. The Ethernet Properties window will open, select TCP/IPv4 and click the Properties button.
On the General tab, select Use the following DNS addresses:
Preferred DNS server: 208.67.222.222

Alternate DNS server: 208.67.220.220

Note: This DNS address is from OPEN DNS (Cisco). You can also use Google DNS: Preferred DNS Server: 8.8.8.8, Alternate DNS Server: 8.8.4.4.

Tip: You may also need to manually enter these DNS addresses into your router and disable the IPv6 protocol. In this case, consult the manual of your operator or router.

Hi there again,

a small update from my side. The manual port forwarding led to an open NAT, too. Testing the multiplayer connection in the X1's network settings, resulted in the following NAT-status: (...) not behind a Cone NAT. Sounds good, the NAT status is open. But
nevertheless, nobody hears me within games. Is there anything in the X1's settings I forgot to change? Every setting regarding social networking is "opened"...

Thanks

Hello PitGaming,

If your NAT is open, then the problem lies with your friends. Even if you NAT is open and your friends is Strict or Moderate. Then you will not be able to connect to them.

I recommend talking to friends and get them to forward the correct ports.

Why NAT is important

[table][tr][td]OPEN NAT[/td][td]MODERATE NAT[/td][td]STRICT NAT[/td][/tr][tr][td]With an OPEN NAT type, you’re able to chat with other people, as well as join and host multiplayer games with people who have any NAT type on their network.[/td][td]With a MODERATE NAT type, you’re able to chat and play multiplayer games with some people; however, you might not be able to hear or play with others, and normally you won’t be chosen as the host of a match.[/td][td]With a STRICT NAT type, you’re only able to chat and play multiplayer games with people who have an OPEN NAT type. You can’t be chosen as the host of a match.[/td][/tr][/table]

To resolve your multiplayer game issue, it will be necessary to recheck your NAT type after each solution we try. These are the steps you’ll need to take to refresh and retest your NAT type:

1. From the Network settings screen, select Test multiplayer connection.
   
2. After the test is complete, you will need to pull and hold both triggers and both bumpers on your controller. This will display a
   Detailed network statistics screen.

[table][tr][td][/tr][/table]

1. In the second column of the Detailed network statistics screen you will see a field called
   Detailed NAT information. At first, you will see (…) displayed in this field while your NAT type is being retested. Once you see NAT information displayed in this field, the test is complete.
   
2. Press the B button on your controller to return to the Test multiplayer connection results.
   
3. Select Continue to return to the Network settings screen and check your NAT type.
   

On the Network settings screen, you’ll need to check to see if your NAT type is “Open”. If your NAT type is “Open”, then that should resolve your multiplayer issue.

Network ports used by Xbox Live
Port forwarding
If you have a firewall or network hardware, such as a router, you might need to make a configuration change in order for your Xbox One console to communicate with Xbox Live. This configuration change is sometimes called “opening ports” or "port forwarding."

Xbox Live requires the following ports to be open:

• 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)

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

How to set up port forwarding

For information about how to configure compatible network hardware, go to the
Networking Hardware Information forums.

You may also find information about how to open ports on your router at
the Port Forward website. If your router is not listed on the Port Forward website, contact your Internet service provider or router manufacturer for help with opening network ports.
