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.
