First: this question is not a duplicate of:
- This question: I don't want to use SOCKS, and I am not asking about Lollipop.
- This question: No answer, and different use case
- This question: I don't have time to develop my own application.
My goal: to find a way to force all internet traffic (including cellular ie LTE) into my OpenVPN server, except for apps on a whitelist. Whitelisted apps either connect to a second VPN or SOCKS proxy (option preferred), or not be connected to a tunnel at all (a "normal" connection).
For example, try out the ProtonVPN application (which, by the way, I recommend). There is an option to whitelist apps from the VPN. This is what I want, but for my own server.
Root is definitely not preferred, but if it's the only option, then I guess I'll accept it. Multiple profiles are also not preferred, but if it allows some apps to be over VPN and others not, then I will also accept that (but I would like system apps to be blocked in that case).
Thank you.
