  1. Strict Nat possible UPNP error


    Hey guys it's been really messing with my gaming. My nat is always strict before it was open and moderate depending on what ISP I used. Recently its been stuck on strict even though before it was never liked that. I can still play games with friends but
    party chat doesn't work and ruins my experience of playing. I'm not sure if I messed it up watching movies through my phone using a UPNP app playing through my phone. My xbox used as a renderer. Now I can't watch movies anymore via UPNP. It doesn't play I
    noticed when it stopped working my NAT went to strict even though I used to different ISPs. Still got strict. I even used DMZ no luck. The NAT detail information says "YOUR NETWORK IS BEHIND A FIREWALL OR NOT CONNECTED" It's been ruining my online experience
    with party chat and I can't even chat with my friends online. Been thinking if restoring my xbox one to factory defaults would remove it and not use my xbox to play movies via UPNP.

    :)

    Port forwarding question

    I have discovered why my X1 reports a Strict or Moderate NAT sometimes and it's after one of the 360s uses one of the ports the X1 needs. As soon as a Live port is used for a 360 via UPnP, 3074 for example, the X1 drops to Strict.

    This is exactly the reason why I use UPnP, because if 360 1 is using 3074, UPnP will map 360 2 to a different port number that grants the same access as 3074 allowing both to communicate with the Live service at the same time, thus granting an Open NAT to all connected 360s. The X1 is not triggering port forwarding via UPnP to utilise this feature, so is the device that suffers when a 360 is in use.

    The PS3 used to have a UPnP enable/disable option on the console itself, which I thought was odd, but perhaps if the 360 had this, enabling it would tell the console to use UPnP, which once it uses UPnP to trigger the ports I'm sure it will resolve the multiple device issue.

    For reference:

    • When I have an Open NAT, the X1's Detailed NAT Information says: Your network is behind a cone NAT
    • When I have a Moderate NAT, the X1's Detailed NAT Information says: Your network is behind a port-restricted NAT
    • When I have a Strict NAT, the X1's Detailed NAT Information says: Your network is behind a port-preserving port-symmetric NAT

    xbox live connection error

    no i have tried that. opening ports gives me a live connection error, turning on upnp gives me strict nat. i have also tried the dmz method but that also gives me a strict nat.

  4. Strict Nat possible UPNP error

    Try taking your console out of dmz. Enable UPNP, in power settings change from instant on to energy saving. Do a full reboot by holding the power button for 5 to 10 secs. Then restart see what happens. If it's open at that point don't go back to instant
    on and you should be fine until a real fix for the problem is in place.
