If you are on Debian/ubuntu, you can rename your iptables script to /etc/network/if-up.d/iptables:
Code:
mv /etc/firewall.bash /etc/network/if-up.d/iptables
and make it executable:
Code:
chmod 755 /etc/network/if-up.d/iptables
The script will then be started automatically whenever you boot the system.
