Strict NAT Type XBOX One S On Orbi LBR20 On AT&T LTE Network

Hi myOrbiLbr20,

Sounds like issues is related to APN used which APN are you using on the LBR20 broadband, nrbroadband or i2gold? I believe the regular broadband APN on AT&T uses PAT which restricts the Xbox and PlayStation connections to strict NAT type. PAT typically has multiple users use same AT&T IP address just different port to id different users on network with same IP. The problem this creates is that the routed traffic does not know how to get back to the correct client hance this creates scenarios where port forwarding does not work very well. I would suggest trying the following go to you LBR20 settings and enable UPnP it should change the NAT characteristics of the LBR20 router mode and may help in this case. If that does not work, you can try setting LBR20 in Passthru mode and connect to Xbox directly this will bypass any routing on LBR20 and if Xbox still has same NAT issue it will confirm a problem on AT&T side.
