How to only access through VPN?

Hi, I would like to know if is possible to only access (http, ssh) specific machines, IF ur using a vpn in flyio?

If that is possible, how can I achieve this?

thanks

May be.

  1. Remove all public ip/port declaration from fly.toml.

  2. And then connect to app vms from your Mac/PC with flyctl wireguard or connect among app vms over 6pn.
