I have a Mac Mini permanently on on my home network and a M1 Max MBP I use when traveling. Have a Gl.inet AX3000. How can I set up a permanent no-monthly-cost VPN and use my Mac Mini as a VPN server?

I have a Mac Mini permanently on on my home network and a M1 Max MBP I use when traveling. I also have a Gl.inet AX3000 I just bought. What is the best way I can set up a permanent no-monthly-cost VPN setup so I can use my Mac Mini as a VPN server that I can run all my traffic to when travelling internationally? I ideally don’t want to pay for a third-party service (why would I need this in this situation???) and want to run my traffic through as few servers as possible between wherever I’m at at the time and my home network as possible for max security.

THANK YOU in advance for any tips/guidance!!!

Tailscale is another option that would be free for your use case.

Perfect thanks so much!! Will give this a go. I really appreciate your time, thanks!!
