Homelab VLAN Segmentation

A practical approach to segmenting a homelab network for security and clarity.

Segmenting your homelab isn't just about looking professional — it limits blast radius when something misbehaves or gets compromised.

Why VLANs matter

  • Isolation — IoT, guests, and lab workloads stay separate
  • Policy — Firewall rules become easier to reason about
  • Learning — Mirrors real enterprise patterns at smaller scale

Start simple, document everything, and iterate. Perfection is the enemy of a lab you actually use.
