Hello Fadishdog,
Greetings!
Thank you for posting in Microsoft Community.
It appears that the Network Address Translation type (NAT) type information has been missing after some recent updates with Windows. Let us work as a team to help us get to the bottom of this.
Previously, you are correct, that to check your NAT type in Windows 10 PC, you can go to PC Settings > Gaming > Xbox Network and check the NAT Type. If this has been messed up due to some updates, we can submit feedback through using Feedback hub app in Windows. See: Provide feedback to Team Xbox | Xbox Support. Follow the steps provided under Report a problem online> Report on Windows.
Additionally, we encourage to send us a screenshot on what you see when you do these steps: PC Settings > Gaming > Xbox Network. And please provide us the version of your Xbox app. To do so, follow the steps below:
Launch the Xbox app on your PC.
Select your profile picture and go to Settings.
Go to About to view your version number.
We look forward to your response. Kindly let us know, if there is any misunderstanding or clarifications of our description by sending us a reply.
Sincerely,
Tomm_A
