Exclude Video Traffic - Global Protect

KyranMendoza — Wed, 23 Sep 2020 09:37:59 GMT

Hi there,

We've setup our global protect to exclude all video traffic, using this guide: https://docs.paloaltonetworks.com/globalprotect/9-1/globalprotect-admin/globalprotect-gateways/split-tunnel-traffic-on-globalprotect-gateways/exclude-video-traffic-from-the-globalprotect-vpn-tunnel.html

The firewall has all the relevant licenses required (GP Portal/Gateway license)

Here is a session that should have been excluded but as you can see by the 'tracker stage firewall: Age out', this should be 'tracker stage firewall: split tunnel' to my knowledge. All reference to 'anon' below is because i desensitized the content.

anon@PA-3020-ha1(active)> show session id 223050

Session          223050

        c2s flow:
                source:      172.16.6.7 [global-protect]
                dst:         anon

        end-reason                           : aged-out

Does anyone have any ideas on why this traffic isnt being excluded? From what I can tell the configuration is correct, but when we try to watch a youtube video for example, it simply attempts to load and never finishes.

For the exclude video feature to work, SSL decryption is required. Please make sure that the sessions are being decrypted via the traffic logs.
I also noticed that this is an HTTP2 parent session that timed out. Is this happening with HTTP2 sessions only?
If the session is being decrypted, have you tried to strip ALPN under Client Extensions under the decryption profile? This will force the session to use HTTP1.1

Please have a look at this doc: https://live.paloaltonetworks.com/t5/general-articles/troubleshoot-split-tunnel-domain-amp-applications-and-exclude/ta-p/321075

You can also check the PanGPS.log on the client-side to see if exclude video feature is being applied. Look for the line below

<exclude-video-redirect>yes</exclude-video-redirect>

Hope that helps!
