Is it possible to block just youtube video music from Fortinet? I need my users can watch videos like tutorials from youtube but not music or another kind of entertaiment.
In a word: no. YouTube provides no mechanisms to allow a network device like a firewall to differentiate between content types. The only method I'm aware of that sort of works is to use a proxy to set a volume quota on YouTube or other streaming media sites in general, high enough so that the odd business use is possible, but streaming music videos all day is not.
