Latest BT HomeHub 3.0A firmware breaks Port Forwards

Just a heads up to save other poor souls the hours I wasted trying to figure out why my home network suddenly stopped working.

Firmware version: Software version 4.7.5.1.83.8.94.1.11 (Type A) Last updated 25/11/12
Board version: BT Home Hub 3.0A

The above firmware update, which I received (pushed) yesterday breaks all the port forwards (Internet->Local) you have.

Breaks as in don't work at all, or you just need to reconfigure them?

Yes, really breaks

I tried reconfiguring by removing the Devices, re-adding them, reconfiguring the Port Forwards and even adding the internal server as a DMZ. No dice.

I posted on the BT forums and seconds later someone else posted the same issue with the same diagnosis.
