First, get your iptables rules set up the way you like them. Once you've verified that everything works, save the rules:

iptables-save > /etc/firewall.conf

Next, open up /etc/network/if-up.d/iptables in your favorite text editor and add the following:

#!/bin/sh
iptables-restore < /etc/firewall.conf

Once you save it, make it executable:

chmod +x /etc/network/if-up.d/iptables

Now, the rules will be restored each time your networking scripts start (or restart). If you need to save changes to your rules in the future, you can manually edit /etc/firewall.conf or you can adjust your rules live and run:

iptables-save > /etc/firewall.conf
