I use 

  sh /etc/rc.d/ipnat reload

(which does a "ipnat -F -C -f /etc/ipnat.conf" internally)

That's the nice thing about /etc/rc.d scripts - you don't have to remember the
details for each of them, since they accept a common set of commands like
start, stop, restart and reload (where the latter is not always implemented,
unfortunately)
