I user PAN OS 7.1.0 and now i CAN'T block youtube although i try using both application and url to block.
1, Block by Application
I created a rule to block YouTube-base
I still view video on youtube normal
In log traffic, i see Palo Alto Blocked Youtube-base application
But i think, traffic from youtube go through SSL and googbase app
2. I user URL Cateogory
I created a URL for Youtube
And after i apply a policy block youtube by using url,
On firefox, youtube is blocked
But on Chrome, Youtube still running
check your traffic log if you're seeing "quic" application, this is a sort of ssl over udp protocol google has implemented in chrome that can bypass your regular policy. you may want to disable quic in your browsers or block it altogether on the firewall
Please check the above document if you do not want to make a change on the firewall if it works you can deny the same on the firewall.
type the below string on chrome
ctrl+f search for quic and disable it, test the changes and let us know.
