I'm currently running Graphene and using the TrackerControl app to ensure that most of the connections to analytics/fingerprinting, etc from my apps get black-holled. This works by creating a VPN connection to the loopback address and routing app traffic through it. This works really well for me.
What I'm looking at doing now is to use a VPN (Nord) for some of the apps instead of TrackerControl but I'd like to keep TrackerControl running for other apps. Pretty sure there is no way to run more than one VPN connection at once though. Has anyone set up anything similar or have any suggestions as to how I might make this work?
