OK, first, this is really more of an administrative issue than a technical one. Tell your employees that if they IM for non-work issues (and that IM is logged, whether it is or not), then they are fired. Get your boss to back you. Then, it's not *your* problem if people are wasting their time at work. Second, the only reasonable way to do this is to block *everything* except traffic you want to allow. No client machine needs direct Internet access to send email - make them use a smarthost. Force all machines to surf the web via a Squid proxy, and only let that machine connect out on port 80. Either way is going to piss off a lot of people, so decide in advance which one you can live with. :) -- Kirk Strauser In Googlis non est, ergo non est.
