Connect to VPN on demand when using a specific App

[sdz]

Is it somehow possible to define a vpn for a specific app on macos?
I know (years ago) I could use tsocks to wrap all networktraffic of a process to a specific socks proxy.

Is something similar possible but for example with IKEv2 / L2TP ?

Do you want the VPN to start when the app starts or just the traffic for the app to go down the VPN (the latter usually is pretty easy (split networking).

Something like that...
For Split Tunneling, I must now the IP-range Process.app could address... In theory Process.App is also 0.0.0.0 (everything), So I can't know.

Basically I want to wrap a vpn around a given process. Something that seems to work in managed iOS devices (per app VPN)
