Allow access to specific YouTube channels on a Fortigate
I am new to the Fortigate and firewall worlds, so pardon my ignorance, but I am looking for the proper procedure to setup access to specific YouTube channels, and what I mean by the proper procedure, I mean what all has to be enabled or disabled in the various sections (Web Filters, Application Control, SSL/SSH Inspection, etc) for it to work. I have setup the rules on the WebFilter to allow specific YouTube channel ID's, I have tried to allow YouTube access on the Application Control and even used custom signatures that I have found on the internet, but nothing seems to work. I either can't get to YouTube at all or I can get to all YouTube.
I work in a environment that content from YouTube absolutely must be restricted.
Any help would be greatly appreciated.
