Core Idea

A VLAN uses tags to split one physical switch and link into multiple logical networks. Even when the hardware is shared, service traffic, management traffic, and guest traffic can still follow different boundaries and policies.

Why It Matters Here

Mathbong uses VLANs to connect Proxmox bridges, OPNsense interfaces, and managed switches into one design. They are the practical tool for making network segmentation precise and maintainable.
