    Thanks very much, I will check this. I assume this will be true
    for IPFW2 rather than IPFW.

    It appears that 1.16.2.23, nov 21 2002, RELENG_4 has this
    from the log:
    "MFC: obey to fw_one_pass in bridge and layer 2 firewalling (the latter
    only affects ipfw2 users).
    Move fw_one_pass from ip_fw[2].c to ip_input.c to avoid depending on
    IPFIREWALL."

    I will try this out.
