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
Basic layout
| VLAN | Purpose |
|---|---|
| 10 | Management |
| 20 | Servers |
| 30 | Workstations |
| 40 | IoT / untrusted |
Start simple, document everything, and iterate. Perfection is the enemy of a lab you actually use.
