There is also this feature in tailscale, but I haven’t used it myself because I don’t know enough about the security implications to use it: https://tailscale.com/docs/features/tailscale-funnel

Great advice and I would like to add to this, if you need something easier to run for VMs, go Fedora Server rather than proxmox. If you find your use case needs a bit more complexity, then go proxmox.

I personally found that proxmox was an overkill for what I wanted out of my (old laptop) server.
