How can I restrict visiting a service through a domain to VPN-connected devices? (lemmy.world)

Say I have a public server with a service (email, web server, etc) that's accessible through https://myservice.example.com, and I would like to restrict that service with a VPN. How do I do that?

I know how to setup a VPN. I know how to use some of the services through that VPN. But see, if I want to use that VPN, I connect my client to that VPN, then I get the subnet of that VPN, say 10.10.100.0, through which I can access the devices by address.

But I see some services offer things like https://myservice.example.com, and they only work when that VPN is connected. How does that work? Is it just some DNS setting at the domain level or there's more to it?

I'm sorry. I don't know enough about the subject. I'm sure there are firewall daemons, or IPTABLES configuration that can do what you want, but that's beyond my area of expertise. Good luck.
