1. Install fwbuilder <http://www.fwbuilder.org/>
2. Design your chains
3. Save the results.
4. Look at the generated script

The odds that FWBuilder doesn't support what you want to do is *very*
*very* low.  As iptables has become more sophisticated and capable, and
then there is IPv6 rule pairing/mirroring... I've abandoned all attempts
to maintain iptable rule-sets manually.   FWBuilder works, and will even
install the rules for you.
