The guarddog packages here have not been intensively tested and not well integrated into the SuSE Linux system configuration.
The guarddog firewall script shall not be started automatically at boot-time, you shall need to add the execution of /etc/rc.firewall at boot-time yourself.
If you have any hints, experience with the way guarddog works, please contact me and I will improve the package. Because I don't use guarddog myself, I won't spend any large amounts of time integrating the package as of now.
