Via the Omada Controller I created a new VPN connection, Client-to-Site VPN -> VPN Client - OpenVPN

I added the remote server number I found in the .ovpn file and I imported the OVPN file.

With the OpenVPN GUI this input works.

What I cannot do is enter my NordVPN credentials somewhere in the router for an OpenVPN connection. 

Is it possible to use my NordVPN account and use this with this router, to have all my internet activity run via a VPN connection using my R605 router?
