How do I fix my nat type if its strict, To allow me for a multiplayer

Hi Phumelelo, I hope you're doing great despite the issue you're experiencing. I am an Independent advisor and I am here to help you in regard to your concern.

You need to open the following ports through port forwarding or by reaching out to your Internet Service Provider.

Here you go:

Port 88 (UDP)

Port 3074 (UDP and TCP)

Port 53 (UDP and TCP)

Port 80 (TCP

Port 500 (UDP)

Port 3544 (UDP)

Port UDP 4500 (UDP)

Ok, so I opened the ports and my NAT type is open, but upon entering Halo 4 multiplayer, I find the notification that the servers are not available and the matchmaking playlist has re-setted to the default. I tried disabling the ports, and it allows me to
enter matchmaking again, but reverts my NAT type back to strict. Any ideas?
