Shorewall is easy to use in Mandrake 9.0 so long as you do not go anywhere near the Mandrake Firewall GUI. The GUI will do weird things to your config. The easy way to set up shorewall is to configure the files in /etc/shorewall by hand. They are well documented and easy to understand. The files of interest are interfaces,zones,policy, and rules You will find excellent documentation at www.shorewall.net Then restart shorewall with service shorewall restart I do not know if the GUI has improved with 9.1 as I have not tried it yet. If you really want a GUI based firewall, then uninstall shorewall and install firestarter from a Contrib mirror. It has fewer features but is 'point and click'. derek
