Updated video for VLANs in OpenWrt 21.02!

Welcome back to Dev Odyssey Home Networking! In this episode I break down VLANs with a example, and demonstrate how to set up your own VLANs using OpenWrt on my Netgear R6080. VLANs have many benefits, notably, creating multiple networks that let you control which networks your devices connect to, and therefore securing them by separating out personal devices, guest devices, and risky smart devices. Once you know how to create VLANs, you can make your own virtual networks for all the devices in your home network.

This video was recorded using the following versions of OpenWrt and LuCI:

VLANs are virtually / logically separated, not physically like regular LANs

VLANs are defined by the 802.1q protocol.

VLAN Advantages

1. Create multiple virtual networks
2. Create special purpose networks for guest users, smart devices, video surveillance and media streaming servers like Plex

VLAN Requirements

1. Physical Interface (Ethernet or WiFi)
2. VLAN ID (1 – 4094)
3. Name
4. Priority (0 by default, meaning Best Effort)
