I have tried to set up two rules in Enpoint Protection Firewall mangement control panel to restrict access to Facebook.
I tried to set one rule to allow access to Facebooke except during certian times but if the client has logged onto to Facebook before the exception time then they can still access Faceboook. It only works if the clients pc is restarted or the client logs out of Facebook first and then tries to login during the exception times.
I also tried to set the allow time so that Facebook was only allowed during certian times (e.g 12:00 to 13:00) however if the client logged in during this time then after the allowed time they were still able to access Facebook.
I also tried to set the Block rule but had the same problem, if the client had logged into Facebook before the Block time then they were still able to access Facebook.
I would like to allow access to Facebook between 07:00 - 8:30 & 12:00 - 13:30 and block access at the rest of the time.
Is this possible using the Firewall rules of Block or Allow?
I am using Symantec Endpoint Protection V12.1 and the clients have Network Threat Protection installed.
