Is it feasible to use PVE 8.0.4 to manage Network Access for devices and network hardware that is external to the Proxmox Cluster? I have an 8 node Dell server cluster but wish to use external fiber switch and router gear to manage both NAS hardware as well as the PVE Cluster and VM's hosted on it. The hosted VM's need to be in many cases accessible to owners/users from outside the network. I have layer 3 fiber routing hardware and an IPV4 //28 address block that needs to be integrated and firewalled. Can this be accomplished from within the PVE server environment? Can I operate a RADIUS server from within the PVE environment and manage an external network as well?
