My guess: Something wrong with the ERX that doesn't hit the windows machines because they tested with those.. The PPPOE implementation on FReeBSD does follow the spec very closely, but it doesn;t act as windows does. This sometimes upsets equipment that just assumes that the world is windows.. do you have packet traces? do a tcpdump on the ethernet interface you are using.. tcpdump knows how to handle pppoe. > > > a) is always possible.
