% man ipfw

     o   If you are logged in over a network, loading the kld(4) version of
         ipfw is probably not as straightforward as you would think.  The fol-
         lowing command line is recommended:

               kldload ipfw && \
               ipfw add 32000 allow ip from any to any

         Along the same lines, doing an

               ipfw flush

         in similar surroundings is also a bad idea.

I expect running jexec(8) qualifies as 'logged in over a network' here?
