VPN Tunneling Server Setup

I need a tunneling server configured so that all traffic is routed through a reliable VPN connection. My preference is to run the tunnel over a standard VPN protocol; however, if you feel SSH or even a SOCKS‐based approach would solve the same problem more effectively in my environment, I’m open to hearing why and adjusting the build.

Here’s what I expect:
• A clean server deployment (Linux or Windows—your call as long as licence costs stay zero) with a fully operational VPN service.
• Clear, copy-and-paste-ready commands or GUI walkthroughs so I can add, revoke or monitor users without breaking anything.
• A quick test plan proving that data is really flowing through the tunnel and that DNS leaks are impossible.

Hand the whole thing over as soon as you have it working on a fresh cloud instance, and I’ll spin up the same image in production.
