yes.  I.E. from 192.168.30.53 I can ping 207.158.72.11, and telnet
to 207.158.72.11.  While that telnet is up, I can log on to the FreeBSD
box, see the translation in ipnat -l, telnet to 207.158.72.11, and see the
session in 207.158.72.11's netstat, but I can't do anything useful on the
session from the 192.168.30.53 box.
