Im trying to configure an IPS 5.1 sensor to block IM traffic. I have been successfull with everything but Yahoo. I thought I had it configured correctly, but for some reason, I can still access it over HTTP. Does anyone have any insight into what I may be doing wrong?
Just a reminder to also block sites like e-messenger.net, meebo.com, ebuddy.com, iloveim.com, msn2go.com, messengerfx.com - do a header regex with the http engine.
