Additional Network Ports for Multiplayer Gaming: Nat type changes only during game play

Hello mjjkkx,

Have you port forwarded any network ports on your console. If you have not can follow this support guide https://support.xbox.com/en-US/xbox-one/networking/network-ports-used-xbox-live.
This should help solve some of your port issues and NAT issues within the game.

Have you tried to hard reset the console? Another option would be is to factory reset the modem; if you have rebooted it already.

I would recommend that you follow the steps on this link and see if there will be improvements. https://support.xbox.com/en-US/xbox-one/networking/nat-error-solution.

There is a chance that you may need to contact your ISP(Internet Service Provider) if changes with your Network configuration or IP address needs to be changed. Be sure to follow the link above since it's tested and proven to work.

I hope all goes well for you.

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.

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. Always check the developer's website to see if the game needs additional ports to run. We've collected information on some ports you may need and added them to the Additional Network Ports for Multiplayer Games forum.

If you are connected to a network at your workplace or school, ask your network administrator to open them.

good monring

The configuration that needs to be changed is from your provider, they use a security device for the network that prevents access to microsoft servers, unfortunately I believe it's just changing providers. It is very likely that the problem is NAT.

you can try to open the ports on your router, but that probably won't do the trick.

see what the ports are and ask for help from the provider to open.
