OpenWRT 21.02 – Setup Guest WiFi

In this video, we will setup guest WiFi on OpenWRT 21.02 with LuCI (no SSH or CLI required). The process consits of creating guest network interface, wireless client isolation and guest firewall zone configuration.
The purpose of Guest WiFi is to create an open wireless network independent from your LAN/WLAN. Devices in the Guest network can only access the internet and won’t be able to communicate with devices in your internal network (LAN) and the router management IP (LuCI/SSH).
