What exactly was unclear in my description?

It's perfectly valid syntax according to ipfw(8).

"out not recv any xmit dc0" consists of three options
(i.e. match patterns):

1. "out" --> match only outgoing packets.

2. "not recv any" --> match packets that haven't been
   received through any interface (i.e. which originate
   from the local host).  It's simply a negation of
   "recv any", see the ipfw(8) manpage.

3. "xmit dc0" --> match packets which are going to be
   transmitted through the dc0 interface.

However, the problem is that the second option is being
ignored, and I would like to know why, and how to work-
around the bug.

Best regards
   Oliver

(On the statement print "42 monkeys" + "1 snake":)  By the way,
both perl and Python get this wrong.  Perl gives 43 and Python
gives "42 monkeys1 snake", when the answer is clearly "41 monkeys
and 1 fat snake".        -- Jim Fulton
