    I would try to use for the pppoe connection a dedicated
    eth-NIC to which the DSL modem is directly connected.

    IIRC NICs with an IP address assigned are supposed to
    cause problems when running PPPoE over it. I can't
    remember the exact reasons, though and I had even
    such a setup successfully running a long time ago.

    However I would give it a try with a dedicated NIC.
    They are very cheap nowadays and such a setup is
    smarter anyway, since the broadcasts of your private
    LAN are not bridged by DSL modem towards your ISP.

    Ciao, Horst
