You can use iptables-save to dump out the contents of your firewall and redirect it to a file:
Code:
iptables-save > firewall.log
You can then retrieve it with:
Code:
iptables-restore < firewall.log
I tend to build the rules in a script and start it at boot time, rather than use the above method. It just depends which suits the way you're working...

service iptables save
I think the above also is a valid choice.

Which (if any) of these commands will enable the saved options on boot?

If none (warning newbish question follows), where/how do I save a script to run on boot?

Thanks,

Steve

In /etc/init.d is the a file called iptables or rc.iptables? It needs to be executable and modified to start up your iptables rules. If there isn't a file call that, you can add the commands to /etc/init.d/rc.local.
