Palo Alto URL filtering and Google Chrome

Hi All,

Was messing with some url filtering at home and discovered if I tried to block *.youtube.com videos the page was still loading on CHROME, even though palo alto logs showing blocking.

I am running PAN-OS 6.0.5

On firefox and safari it was blocked.

Here are logs showing Palo Alto was blocking but it really wasnt.

So I looked into google ssl certs and saw this googlevideo.com

Blocked the following and it worked,

custom-block-url-4.png

So it looks like chrome will try other dns names if it gets blocked at first while firefox and safari don’t J

Thanks

Arnold
