I bought a Mikrotik hAP ax lite LTE6 and updated it (Installed Version: 7.14.2 and Firmware: 16121.1034.00.01.01.04 ).

I want to apply NordVPN into it. The Quick setup doesn't allow me to change VPN Address at all (as show below.)
I'm not familiar with setuping routers or savvy with computers. This is the first time I try to apply VPN directly into the router. I have an URL-address for the VPN plus my username & password for the VPN. I have no idea where to find the VPN setup in the menu (as show below).
What to do? Please explain in details and plain English. If I need to write any commands into the Terminal I'll just use copy-paste and hope for the best

The VPN access shown in Quickset is INTO your device, coming from the outside.
That's why the VPN name can not be changed there, it's based on a unique name tied to your device.
This has nothing to do with setting up VPN towards a 3th party service.

You may want to revert to NordVPN instruction how to set this up.

Thank you, the instructions were simple and the VPN connection works now!
