Sorry previous messages is incorrect (I had in mind downloading files) Hello Daniel, Most likely, we not absolutely understand each other. I would be very glad if there was an opportunity to add in PF feature which possesses IPTABLES. On a gateway for a local network in rules of firewall it is possible to add a following line: -A FORWARD -s 192.168.x.x -p tcp -m string --string ".mp3" -j DROP If the internal client of this network requests a resource with name containing ".mp3" he will not receive the answer (www.mp3.com, www.music.com/Mozart.mp3, etc.). Accordingly similar is possible to make with words "porno" "avi" and etc. I do not consider that it is 100 % protection against downloading (from internet) by users mp3 files. Certainly, there are ways for detour of similar interdictions created both by proxy-servers and by firewall. However in most cases this rule will be enough. I do not see sense in the bet offered by you as there is a talk a little about other! Certainly, clever and talented person as you are will find a way to bypass interdiction!!! P.S. If for any reasons, it is not possible to do so, "c'est la vie" Best regards Alex
