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
