We currently have a Model 410 Web Security Gateway. When I first enabled SSL inspection, Facebook Chat was being blocked. Now, even though it is in the list to be blocked, Facebook Chat is not being blocked. We want employees to have access to Facebook and some employees are tasked with periodically updating our Facebook page so I can't kill all of it but Chat has become a huge issue both in terms of productivity and attentiveness to the job as well as liability/legal issues.

I would recommend contacting support directly to investigate this issue, there could be many causes for something like this presuming all of the prerequisites are in place such as certificates, etc.
