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.
