Why does my NAT become strict when I play BO3

My NATs always open and I've been getting matches in Halo 5 no problem this past week. But when I try to play Black Ops 3 my NAT becomes strict. So I took out the disc and restarted my Xbox, it changed back to open until I tried to play BO3 then it's strict
again.

:)

 

Can't find wireless network

Wired connection seems to work.

NAT is showing as 'strict'. Wonder why the wireless is playing up.

 

Xbox NAT test OK but game says otherwise.

When I run the systems check for my Xbox it gives me no message about my NAT being moderate or strict . Meaning it's open , correct?

But when I play certain online games it tells me my NAT is moderate .

Who do I believe and why does it come up different.

Thanks in advance.

It seems as part of the demonware services (used as a mean to provide services for online-games) does not seem to function properly with the UPnP protocol suite.

If you only connect one Xbox console to your router and Internet connection, then try disable UPnP and configure your Xbox Ones IP address in the DMZ of your router.

You don't have to make a static IP for your Xbox One (very few devices on the same segement need a fixed, or static IP), as long as your router/NAT device support DHCP reservation, or IP reservation. Then it's better to use the DHCP reservation and apply
this IP address in the DMZ of your router.

Note! The recommended steps only apply as long as you connect one Xbox console to the same router.

Keep us posted!

 

I'm not tech Savoy,don't know how to do that and my ISP(att)won't help anymore.
