Covers the difference between managed and unmanaged switches, tagged vs untagged ports, making Proxmox VLAN-aware, creating VLAN interfaces for cluster communication and HA links, and enforcing inter-VLAN firewall rules in OPNsense. Includes a live demo of assigning VMs to different VLANs and verifying firewall rule enforcement. ## Full article daily.dev links to this article rather than hosting it.
