Mike,
It does indeed seem we have the same end goal in mind even if certain methods of achieving it are up for debate, however now is not the time and PPRuNe is not the place.
In the end, I think it has been correctly identified that UPNP was to blame here which, like WiFi and all the other residential technologies sold as a way to make your life easier, are so easily abused and mis-configured due to the manufacturers and resellers focus on marketing and sales rather than product development and user education/support.
As for pointing fingers at BT and Homehub .... I will leave that one as an exercise for the reader.....
