https://en.wikipedia.org/wiki/TR-069 In the UK I'm thinking of the 2Wire routers issued by BT to their business account users. You could configure them for different ISPs, set them up in fully bridged mode, etc., but then you had to also poison the DNS addresses used for their provisioning servers to stop BT updating the firmware and crippling some of its functionality. I can't recall the ritual you had to entertain when changing their settings from BT to another ISP, but it was not as simple as pressing the reset button. You had to navigate to some (hidden?) menu option and change settings from there. -- Regards, Mick
