Install OpenWRT 21.02 & DSA VLAN Configuration for WAN Interface

The first stable release of the OpenWRT 21.02 stable series is now available. It comes with a lot of new changes, for example WPA3, TLS, HTTPS and initial DSA support for some of the targers, including ath79, mvebu and ramips (mt7621). At the same time, the Switch page had been removed and we need to configure VLAN on Network – Interfaces – Devices Tab.

In this video, we will install OpenWRT 21.02 on the Linksys WRT1900AC. After that, we will configure the WAN interface in DHCP client mode on VLAN 30. You can follow this tutorial to configure PPPoE with VLAN on OpenWRT 21.02, all you need to do is change the Protocol of the WAN interface to PPPoE, instead of DHCP.
