I was having trouble with joining people on Xbox One due to my LAN being strict, so I decided to port forward through the xFi website. I have my device on a reserved IP address, and when I view the device details in the website it has the right address, but when I go to port forward on the device it says that the device's reserved IP is something different, so it doesn't work. Does anyone know how I can change this so that the ports are forwarded on the correct address?
I have escalated your issue to the Comcast Team available to these forums. Check back often for a reply in this thread from a Comcast Official Employee.
I've used the email address you have registered with the forums to send you a document that provides more details about port forwarding. Could you please review it, follow the steps to see if it resolves your issue?
