I have a bit of a challenge here... my client wants to block access over the entire network to sites such as: facebook, myspace, mail.yahoo.com etc....
We have a WatchGuard 550 Core firewall in place, its fairly new as well... The Webblocker subscription was a 3 month trial that was in place by default and has expired. Now that the need has arisen to block sites i find it hard to believe that the "only" way according to Watchguard is to purchase this "Webblocker" service add on that is $670.00.
Is there any 3rd party software I can install on client machines or via group policy that would stop users from going to certain sites? Any ideas would be greatly appreciated!
