PPPoE = PPP (point to point protocol) over ethernet. This puts PPP packets into ethernet frame (layer 2). PF is a packet filter and works at layer 3 (IP) and 4 (TCP, UDP, ...). It doesn't operate at layer 2. I think you get the picture. That's why PF is unable to filter AppleTalk, IPX, ... either. Cheers, Dries -- Dries Schellekens email: [EMAIL PROTECTED]
