John - personally I put my iptables script in /etc/iptables.up ( I also
have an /etc/iptables.down )  You can create those files and make them
executable, then call them from /etc/rc.local: -   or call them for example
with pre-up or post-up, post-down from /etc/network/interfaces to have them
run when the network comes up/ goes down.  For example
in /etc/network/interfaces :

iface eth0 inet dhcp
        post-up /etc/iptables.up
        post-down /etc/iptables.down
