Cpanel in Proxmox

Cpanel does not support NAT I am obliged to have a public IP cluster with Proxmox, but I am concerned about security.


This configuration with a public cloud with Proxmox, if you set up a proper firewall, Cpanel would be correct and work as a Proxmox Virtual Machine Cluster?


But as I can have a Proxmox cluster with virtual machines running with cpanel?

Thanks.
