Thanks for your answer Eric.
I actually looked up your proposed solution that you suggested 2 months ago, but Although you explained the basics and the theory behind it, you did not provide any steps and how to go and apply that procedure.
In the meanwhile to answer your question, when I execute the command tailscale status I get direct connection meaning that I'm not behind DERP.
Could you please guide me on how to use VPS or whatever you're using while keeping my solid kill switch to prevent location leaks?
