There seems to be many ways to do this, but in our network we create a
firewall script (similar to how you have done and we do a whole bunch more
than just set iptables rules in it) and we stick it in /etc/init.d/if-up.d/.
Then I add to the /etc/network/interfaces file to the public interface 'up
/etc/init.d/if-up.d/firewall.sh'. Then whenever the interface is brought up
our firewall script gets run. So far, after 4-5 years of this it works like
a champ.
