Xbox One NAT type: Strict.... Help

If it's still strict after you open the proper ports, try resetting your modem and router, then hard reset your console.

This site will help you open the right ports
Open Port

Just select your router and follow the instructions. Do not download anything from the site, it's not necessary. It's a safe site, but port forwarding manually is very easy.

 

Xbox One NAT type: Strict.... Help

I've watched videos on YouTube on how to change it to open & it worked. The question I have is, how do I keep it on open permanently? Every time I turn my Xbox off & then on a few hours later, it's back to strict. It's getting very annoying.

 

You can't use port forwarding or DMZ if you own more than one xbox. You need to use UPnP exclusively.

Please list the make and model numbers of your modem and router.

Someone with knowledge of them may be able to help you
