This script can be placed in your init.d folder to start as a service. I have it in 
/usr/local/sbin as it allows me to execute from any folder.
Also, please remember to 
chmod +x h.sh after saving the file in order to make it executable.
Usage: h.sh start | stop | restart
Produces similar output to 
service iptables starth.sh#!/bin/sh
