To oversimplify it, yes. It really is ISA that makes this a difficult scenario. Even then, it's completely dependent on Windows and the upstream devices playing well in the dead gateway detection" sandbox. A failure of one means a failure of the whole setup. That's why you'll find folks recommending products like RainConnect; it's a much more network-aware method and far more reliable.
