Windows 10 Xbox Play Anywhere not working. Server connectivity: Blocked!

Anyone know if it's possible to play a Play Anywhere game behind a Sophos UTM?  I'm getting server connectivity blocked.  I've gone through the teredo troubleshooting/uninstalling steps and have created a NAT rule as well as IPS exception and Web filtering changes.   Here are the screenshots of what I'm seeing and have in the UTM.   Let me know if anyone has steps to get this working as it's extremely frustrating.  I don't have     any issues playing online from the Xbox itself. 

Thanks,

Gary

  • Hey Gary,

    if possible I would try to deactivate the web proxy for a moment while your Any FW Rule is still active and test again. But in generell you are now down to packet captures or searching for connection specifics of xbox play anywhere and of course check the Rulz.

     

    Regards

  • Ok I'll give this a try tonight.  I completely turned off web filtering and intrusion detection and a game in particular still won't connect on Xbox or the PC.  I don't have that any rule active anymore though so will check later.   Thanks.  Gary

  • already tried a couple of things at lunch...   Now the Xbox doesn't connect to the game in particular at the present time (Sea of Thieves) Xbox says NAT Open but upnp not working.    I can connect to Xbox Live but when trying to connect to a game session it bombs out.  

    - turned off web filtering

    - turned off IPS

    - turned off advanced threat protection

    - added xbox one (0.34) any any rule as #3 in the list (1 and 2 weren't an option)

    - verified my dnat rule was there to send xbox live data to my xbox one.  (I'm not sure if this is correct).

    Opened up firewall port logging and saw the green lines for all connections 192.168.0.34.

     

    Still no go...

     

    Connected my cable modem directly to the xbox and NAT Open and upnp error went away.   

    All worked perfectly and I was able to connect to the sea of thieves servers. 

     

  • well just found this port to try to add to a DNAT rule.    I'll try this one when I get home. 

    Port Forward Sea of Thieves on Xbox One

    In order to play Sea of Thieves on Xbox One you need to set up a static IP address for your console as well as forward the standard Xbox Live port of 3074.

  • Ok all.  This is now solved.  The issue was the MTU size on the wan interface detected by the ISP.  It was 576.  Support showed me how to log into the shell and turn this autodetection off.  Then changed it in the gui to 1500.   That solved the issues I was having and explains why nothing was in any of the logs.   Crazy.

  • Gary...I made an account here just to say thank you. You have no idea how much headache you have lifted from me. I have spent hours upon hours over the past few days trying everything to get my server connectivity unblocked. I have logged six hours with Microsoft support over this issue. You are my hero, Gary. I love you in the manly way.
