Portscanning is way to easy, and popular.. everyone has a scanner, everyone uses a scanner.. Changing the port would just make it so that they would scan for what is there.. Only delay it by a second or two.. The real solution is to remove all such backdoors.. I dont recall about EVER reading about this in the documentation on the router.. If this is in there, what else is there? Is there a back door that would give someone root on the router?
