I want to block all video treaming with palo alto. do do following this:
1, go to Objects--> URL fitering--> add new URL fitering with name block_video.
2, in categories, I check in streaming-media and choose block.
3, I create the policy with full internet, and in action tab --> URL fitering --> Block_video.
But users can access video normally, Please help to advise.
You can do a best effort and simply leave the URL side of things out at that point then. The one thing to take note of here as @markus.wissgott mentions is that this is going to be exactly that best effort. The firewall will likely pass a few packets before it's able to identify the streaming traffic, so streams will first appear like they were and then break.
Other times you'll likely never see any app-id that would indicate streaming anything, so the firewall will simply allow the traffic across certain sites until/unless it properly identfies things.
Just in general I would say this is kind of a terrible idea if you aren't going to go full hog with it.
