Yes, kind of makes sense. If the icmp fragmentation get lost somewhere
(by someone "overzealosly" denying _all_ icmp packets), and this is
all you see of it (this only one sender), it is very likely that the
"denying" is done close to them.... not you. In which case it is a
problem you simply cannot solve (without interraction with ... them).
One could say "they get what they deserve":-).

Ah yes. In my semi-corporate .gov environment, these things can
usually be handled (if it is a "relevant contact", at least)... and
the rest be damned:-):-). I appreciate that you might have a somewhat
different situation, but it is rather likely that there is nothing you
_can_ do:-(.

Then again, I might be wrong:-)
