ipfw(8) man page:
FINE POINTS
� There are circumstances where fragmented datagrams are
uncondition�
ally dropped. TCP packets are dropped if they do not contain
at
least 20 bytes of TCP header, UDP packets are dropped if they
do not
contain a full 8 byte UDP header, and ICMP packets are dropped
if
they do not contain 4 bytes of ICMP header, enough to specify
the
ICMP type, code, and checksum. These packets are simply logged
as
``pullup failed'' since there may not be enough good data in
the
packet to produce a meaningful log entry.
Fragmented packets like that are probably due to broken hardware on
your network, although they can be the result of enemy action
