Hi,

you can add the rule and then run "service iptables save" - it will
save the current rules in /etc/sysconfig/iptables

when you run "iptables" or "iptables -S", it prints only the filter
chain by default. Try "iptables-save" - it prints all rules. The other
option is "iptables -t nat -L -n" or "iptables -t nat -S"

Hope it helps.
