Router on a Stick: Setting Up OpenWrt on Raspberry Pi for Home Network Management

Learn how to set up a Router on a Stick configuration using a Raspberry Pi 5 and OpenWrt in this 19-minute technical tutorial. Explore the concept of single-interface routing through VLANs, which allows a device with just one ethernet port to function as a complete router. Master the essential configuration steps, including VLAN tagging for WAN and LAN networks, proper interface setup, and switch port configuration. Discover why this setup is commonly used in industry and consumer routers, along with its advantages and limitations. Through detailed demonstrations and diagrams, gain practical knowledge of implementing this network architecture using a Raspberry Pi, OpenWrt software, and a layer 3 switch for VLAN routing and connectivity management.
