    Hello Friendly FreeBSD people.

    Let me get straight to the point.

    I am implimenting a FreeBSD Based Firewall.

    I have an ADSL Speedtouch 5200 Modem/Router, Currently Plugged into my
    Switch.

    I want to connect the ADSL modem to my FreeBSD Firewall;
    So that the FreeBSD Firewall will be creating a PPP connection directly to
    my ISP.
    E.g., my vr0 interface will have a PUBLIC Internet Address (IF Possible?).

    My Isp Uses PPPoA, i used the instructions from the handbook;
    Using 'mpd'.
    I set the ADSL router in 'bridge' mode and connect the Ethernet cable
    from the Dsl Router/Modem to my FreeBSD Firewall. ON the Interface vr0.

    But i have little success getting the results i want. [The Firewall doesn't
    connect to my ISP]

    Anyone willing to give me a clue?
