Thank you for the links. I was aware of that, but requires that every connection
directly to the modem, send the PPPoE creds to the modem. While it's simple enough
to connect a router/switch between the modem, and clients, it adds an additional
hop. I think I'll be better served building a (free)BSD kernel, and drivers for
the modem -- assuming that because the modem doesn't IP6, it's not possible to
route IP6 traffic directly, unless through a "tunnel broker".
