There is a destination site with most of the messaging sites prepopulated on my website at www.isaserver.bm. Import it and create a https / https deny rule using it.

Now, we need to block MSN Messenger for all users, and after that, abilitate it just for a small group of them. We know that editing the rule that gives access to HTTP and HTTPS, by Signaturing the Messenger in the Protocol Tab, we can solve the problem, but to get into that option I have to press the button "Filtering", and that button is disabled. Can somebody give me any idea of how to solve this issue? Thanks, JNB
