Hello, i'm having a closer look at iptables for the moment and found this usefull script. At least it's usefull to me since it contains a lof of stuff that i find necessary and it's clearly explained so that it's understandble. http://www.linuxguruz.org/iptables/scripts/rc.firewall_004.txt The site itself also contains other scripts and a lot of links on the subject. Kind regards, Benedict
