Hey folks,
Using PAN-OS 7.1.15 and Globalprotect client 4.0.1.
Trying to confirm something. From what I can tell, when connected to VPN via GlobalProtect, my general internet access goes through the VPN tunnel route successfully (after security rule between the zones of course).
That is the case, correct?
Split tunnel is just not available or possible until this 8.0 feature?

there isn't one...
it's the network settings tab (in your picture)

I think you have read that wrong. Split tunnel has been available since day 1

Thanks MickBall
So much to learn. 🙂
This 8.0 documentation is confusing to me. Makes it sound like exactly what I am asking about and says new feature.
Looking through my current GlobalProtect configuration and do not see indications of where or how it is split up.
Not sure exactly how to tell when connected and not connected if traffic is going through VPN or not.
If you have any more specifics, let me know.
Thanks again.

Your split tunnel settings are located at:
Network->Gateways->yourgateway->agent->client settings->choose the config->Split tunnel tab

Though split tunnel has been there since the beginning, prior to 8.0 you couldn't exclude a network. You had to do it all with inclusion, which was tedious if you wanted to allow a /8 but only exclude a few subnets within it.
With 8.1 and GP 4.1 out now as well, that can go even further by specifying apps that you want to split:
The "New Features" guides show only changes from the previous major release, but I can see the confusion because it doesn't make it obvious which part of the screenshot is the new feature and which is the existing. Once you get familiar with all the features, the incremental changes are easier to handle 🙂

Thank you for that @Mick_Ball
We have internal networks added to our Access Routes. Reading the documentation, it sounds like the fact we have (internal) entries added here, only traffic to these internal routes will go through the VPN tunnel and everything else (like general internet traffic) will not go through the tunnel. Sound correct?
For reference.

yes, correct. this is known as split tunneling.
the routes in your config are classed as included, on the newer version you can also add exclusions as @gwesson previously stated.

Thank you all for your feedback and your patience. 🙂

One thing to be aware of, though, is that split-tunnelling only works on Windows/macOS.
It doesn't work on iOS/Android (it's everything through the tunnel or nothing through the tunnel. And it doesn't work on Linux as there's no working GP Agent yet (there's a buggy 4.1 release that's nowhere near production-use worthy).
We went down the rabbit-hole of trying to get a split-tunnel setup working on iOS/Android for several weeks before getting confirmation from PA Support that it's not supported. The Agent will happily copy the Gateway configuration, including the split tunnel stuff, and then happily ignore it.

Thanks @fjwcash
I think I just proved Split tunnel is functional in my test because I disabled my security rule that allows access from VPN zone to Untrust and general internet still works on remote client.
Feeling better about this now. 🙂
