I installed ProxMox because I want to run ProxMox on metal, and spin up the OS image I need for a given workload as needed.
So, I kind of fumbled through the installer and noticed once the system is up and running that the debian OS that ProxMox is packaged with appears to be a headless OS.
I have Metasploitable VM and Kali VM installed on my server. I wanted to setup Metasploitable to local connection only. Do I need to set a firewall rule for Metasploitable VM? Or is there a way to configure it as a local connection only.
