using a script at startup

[dvdljns]

I am trying to follow the info on Getting IPTables to survive a reboot

eveything works untill I reboot but the script does not run when linux starts.
The article says to create a script so ifupdown loads these rules on boot:

echo "#!/bin/sh" > /etc/network/if-up.d/iptables 
echo "iptables-restore < /etc/firewall.conf" >> /etc/network/if-up.d/iptables 
chmod +x /etc/network/if-up.d/iptables

it put what I think is a symlink in if-upd but iptables still does not survive reboot.
What am I doing wrong.

An easy way is to put your iptables cmd in a bash scripts, let say in /usr/local/bin or whatever, make it executable (chmod +x) and just call it in /etc/rc.local
This will run your ruleset in the boot process, just after services (network, ...) will be started.

 pre-up iptables-restore < /etc/firewall.conf

stuck that in interfaces. seems to work.
