[PVE-User] Setup a cluster proxmox behind just one public ip address

[Jean-mathieu CHANTREIN]

Hello. 

Is it possible to configure a proxmox cluster behind a single public IP address ? 
If possible, how do I configure my nodes at the time of installation ? I don't see this configuration in the documentation. 

If not possible, should I have the same number of public ip address than the number of node of my cluster ? 

For information, I want to use a dedicated network for corosync. 

Best regards.
