Help with a strict NAT on Xbox One?

I am trying to play through all four Halos on Legendary with a friend but I cannot join him and vice-versa. I can play multiplayer fine as long as I am not the party leader. I say my NAT is set to 'strict' so I am assuming that is the issue.

I have given my Xbox a static IP from my gateway's options, I then put said IP in the gateway's DMZ. I then got on the Xbox One and put in the IP manually. Rebooted and it is still set to strict.

I have tried all sorts of other options, the RB, LB,RT, LT technique, going to 'power saving mode, etc.

If it helps the Xbox One, 360, my three PCs are all hooked up to a switch which then runs directly to the gateway. There is also another Xbox One on the network who's NAT is set to open as well as another 360, plus other computers and wireless devices.

Any help would be greatly appreciated.

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.

 

Your gateway may not have the capability to have an open nat for all those xboxs. Your best bet would be to get a regular modem and a router with such a capability like the Motorola surfboard.

 

@Blind Spider 11 hey hey

Can You post what exact NAT status You got when doing RB+LB+RT+LT combination after network test?
