    Type: Error
    Event ID: 64

    Received a PPPoE Session packet with an incorrect payload length; possibly fragmented. Ignoring this packet.

    Every 125 seconds, Eircom is sending everyone what seems to be an invalid packet - a 50 byte ethernet frame, but with a 50 byte PPPoE payload length, which is just plain impossible. A 50 byte ethernet frame, less 12 bytes of MAC source/dest, less 8 bytes of PPPoE header leaves you with an absolute maximum PPPoE payload of 30 bytes.

    I've captured these things - they're IGMP packets sent out every 125 seconds, which is reasonable enough, and the IP headers say the payload should indeed be 30 bytes.

    I don't know what that hex data is you're getting from RASPPPoE, makes no sense to me. Too many zeros, too much missing stuff - no Eircom-like IP address, no IP protocol number 0x0021.
