Actually, I used to do this, too...what I've found, instead, is that it's
better to maintain an iptables script, into/from which you can add/remove
rules.  Then, you can run that script, make sure that the rules are doing
what you want, then run "service iptables save" to save them as the
default, or "service iptables restore" to bring your firewall back to the
state it was previously in.
