NAT Type Strict

  • Hello All,

    I am getting a strict NAT type on my Xbox. I have all the recommended ports forwarded as well as setting a static lease on the Xbox. I have ATT fiber so I have an IP passthrough configured using the MAC address of the Alien router. When I run an open port check, I get a closed response for some of the ports I have forwarded. Any ideas what I could be missing? I tried removing the IP passthrough and just putting the Alien router in Bridge Mode, but that was not successful.


    I was able to get the NAT open. Tried putting the Alien router in Bypass mode again. Removed the IP passthrough on the ATT modem/router and rebooted both. NAT is open now.
