Comment Maybe it is for manufacturing? (Score 1) 236
If I were to venture a guess, things like turning off and on LEDs remotely sound like something that one would want to do when manufacturing as part of a functional tester. That doesn't mean that the way they are doing it is good, but I bet it is so that they can just plug in a router and connect up to their functional tester to test the system to ensure things are working correctly, such as the LEDs.
Seems like if they want a feature like this to support manufacturing that it should be something that is only accessible on one *internal* (non-ISP facing) Ethernet port and only within a certain amount of time since bootup.
