iptables port forwarding doesn't persist after restart

Question

I have server instance running on amazon ec2. I want to forward from port 80 to 8080 using iptables. Which works fine until restart when it stops forwarding. I have used

iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to 8080

to set up fowarding. What do I need to do to make it persistant?

Thanks

You can use the `iptables-save` command – bevacqua Sep 23 '13 at 20:26

You have to run your firewall rules at boot time.
