Utilizing a NSA 220. I've been asked by a manager to block (1) employee from Facebook.
While I see a method to block Everyone from a social networking site and then to Allow certain individuals or ranges, I do not see an elegant or easy way to block a single workstation, while leaving the rest of the people or IPs unrestricted.
I would like to see instructions for this particular scenario. Lowest impact for the rest of the users is required.
