Or make your changes to the iptables config file, then run:

/etc/init.d/iptables restart; sleep 15; /etc/init.d/iptables stop

Note:  This must all be typed as one line.


The "restart" flushes the rules and loads the new ones.  Then your
script sleeps for 15 seconds.   If everything went fine and you haven't
shot yourself in the foot, simply hit "control-c" to abort the script.
If your foot is bleeding profusely, just wait 15 seconds and you'll have
access again when "iptables stop" runs.

The crontab trick is neat, but you can set yourself up with some
possible race conditions.
