NetNanny like app for router based internet connection

DSL connection is shared via a router to 200+ peoples. Some of which are in the computer lab, which changes out computers pretty often. A few of the higher functioning MR/DD clients have found out that porn is available on the internet. We have a free app that blocks it in the lab but there are several computers that are unattended for long stretches during the day that do not have the app on them. So rather than hassle with installing (and reinstalling ad nasuem) the app to block those sites, I'd rather find an app that can do it on the traffic as it comes through the router.

websense and surfcontrol are probably the most popular, they can work as add-ons to firewalls or in 'generic sniff the packets and reply before the real webserver does' mode.

But it doesn't belong in the lounge and it isn't worth 500 points. go ask it in networking or security area and delete this.

stone, I think you're out of luck here, that appliance doesn't have the capabilities to inspect the contents of the packets for objectionable content

Surfcontrol will do it, you need a server to install it on, 512MB ram and 1GB disk space, and a hub inbetween your LAN and your router. There's a flash movie of how it works at http://www.surfcontrol.com/products/web/Platform_Web.html (click on the platform independant button). You can download the demo but it might be too expensive, something like $3000 for 200 users.

You are going to have to set up a "real" firewall.  ie: a computer with two NICs and appropriate software.

I went with SecureSchool http://www.k12usa.com/secureapp.asp , I got a rack server and updates for a year for $1800. They configged it, all I had to do was plug it in.
