I recently purchased the Flint router (GL-AX1800) with which I want to replace my old Asus router.
I currently have internet with DIGI (Spain) which installs an ONT + Router (currently replaced the router of the provider by the Asus). For the internet connection to work I need to be able to configure the WAN with vlan 20.
I have seen how to do it on other GL.inet routers but I have not been able to do it on this one. In Network > Switch I can enable the “Enable VLAN functionality” check but it does not let me add any VLAN in any connection.
How can I fix this?
