Doesn't the system-config-securitylevel tool do that when you check an
interface you want NATed in the Customize area? It should poke the
right iptables rules and turn on the correct flags for you and put
them in the officially sanctioned places (likely adding them to the
end of /etc/sysconfig/iptables). I have always done it manually (by
adding the approriate rules to the end of rc.local) or semi-manually
(by adding all the NAT line into my fwbuilder config) so I can't
personally verify the efficacy of the s-c-s approach but it makes the
most sense to me for someone with simple firewalling needs.
