Mandrake 8.0 firewall app. configuration
 

When I installed M8, I configured a firewall with the GUI app "Tinyfirewall". I clicked through a bunch of yes/no check boxes and saved the configuration.

Opening Tinyfirewall on subsequent occasions alerted me, "You already have a firewall configured. Do you wish to change these settings?"

Now I'm spending some time learning about firewall design and doing it from the command line. But, if I run iptables -L, it shows an empty table of rules, making it look like I don't have a firewall.

Where does Tinyfirewall write its rules and is it running netfilter as its firewall engine?
