I recently discovered these forums and this appears to the the right place to ask for help, my problem is as follows;
Last Friday we upgraded from the BT HomeHub 2.0 to the BT HomeHub 3.0 (along with the BT Openreach Modem). This upgrade was due to our area getting BT Infinity, which has been excellent so far, but for some reason I can NOT open ports to the outside world. I know how to do it and that the BT HH3 doesn't allow for loopback connections so I am using my HTC Wildfire with WiFi Hotspot to test.
I hope that some one can help,
I think it may have something to do with the Openreach modem but I don't know how this affects things.
