A practical guide to separating staff, guests, cameras, phones, IoT devices, and point-of-sale systems.
Why segment a network
Segmentation limits unnecessary communication between device groups and improves troubleshooting.
It is especially useful for guests, cameras, IoT, and operational systems.
Common VLANs
Small businesses often separate staff, guest, camera, voice, IoT, management, and POS networks.
Not every business needs every segment.
Firewall rules
VLANs alone do not define access. Firewall rules control which networks can communicate.
Rules should be documented and tested.
Wireless and wired assignments
WiFi networks can map to VLANs, and switch ports can place wired devices into the correct segment.
Clear labels reduce future mistakes.
Keep it manageable
Overly complex designs can become difficult to support.
Use the minimum segmentation that provides practical value.

Do I need managed switches?
Yes, VLANs require compatible managed gateways, switches, and access points.
