here is the error.
You made the change in /etc/sysconfig/iptables, and did not make the
changes in the running rules.
You then did the "service iptables restart" in step 3 and overwrote the
rules you had entered with the stock rules that were already running,
throwing away your changes

As has already been suggested,
1) Make the changes in the running rules.
2) save the changes with "service iptables save"
3) reboot and confirm the changes are now in effect.
