Hello everybody,

I'm running Debian GNU/Linux sarge-sid (Knoppix) on a PIII box. I have been working in my iptables rules for accepting input packets and everytime I reboot, the system 'refuses' to recognize my ruleset and delete it. The exact message system gives at boot is:

Aborting iptables load: Unknown ruleset, 'active'

I don't know where these rules are stored or anything. I don't reboot my computer frequently but when I do it all my firewall settings go to the toilet.

I would really appreciate any kind of help. Greetings,

Once you have made a set of rules, you need to save them into /usr/lib/iptables/active.

Do /etc/init.d/iptables save active and they will be placed there ready for reboot.

Thank you for your first reply.

I 'remade' my ruleset and then typed the command, logged as root. Returned:

Saving iptables ruleset: save "active" with counters/etc/init.d/iptables: line 65: /var/lib/iptables/active: No existe el fichero o el directorio (File doesn't exists)

What might be happening?

I had exactly the same problem with Knoppix (and stumbled onto your post when I googled the problem). I have since worked out that to make the command "/etc/init.d/iptables save active" work in a HDD install of knoppix, you need to create the folder "/var/lib/iptables" first:
