Home network vlan design. You can find them in most organization with a properly configured network. In case it wasn t obvious vlan stands for virtual local area network and they re ubiquitous in any modern network beyond the size of a tiny home or very small office network. Tagged network traffic contains vlan id info and would only be accepted by devices that carry the same vlan id. Vlan 10 for the secure network where your phones tablets computers and nas live.

Vlan 20 for the device network where all your connected devices including smart tv speakers lights thermostats etc. Just take a look click to enlarge. These include vlans 1 and 1002 1005. In the early days of networking splitting a network into segments required a router.

Vlan 30 for the guest network. The design is exactly the same as if you had a dsl port on your router instead of vlan 7 and then hooked up a bunch of dumb switches all over your house. In doing some background reading on good network design i have seen that segmenting the network with vlans has some advantages even for a relatively small network such as mine within a home.
