Mastering Proxmox - Third Edition

Datacenter | Firewall

The Proxmox built-in firewall is one of the most prominent features in recent versions. It allows firewall rules down to the virtual machine level while protecting with cluster-wide rules. A firewall works at both the cluster and virtual machine level, which can be configured to allow or deny connections to and from specific IP addresses. Any firewall rules under the Datacenter menu apply to the entire cluster. Chapter 9, The Proxmox VE Firewall, has been dedicated to learning about the firewall feature in greater length.
