The only way I see to setup a vpn is within my Omada software Controller's VPN setting whereby I can select Site-To-Site or Client vpn. I selected Client vpn and imported the OpenVPN config file that I downloaded from my NordVpn account. For the Remote IP and port, I entered the remote ip and port that's shown in the OpenVPN config file. It created the vpn and it's enabled, but how do I connect it?

Also, NordVPN provides a username and password for the vpn but I don't see an option in the Omada vpn config to enter it. If I go to the Vpn User tab and try to enter the username/password, there's no option in the Vpn Server dropdown to select the vpn to use. If I'm supposed to add it to the openvpn config file manually then how do I do that?  

None of my devices seem to be using the NordVPN vpn that I created in the TPLink router. Omada software doesn't even give  you any indication whether it's connected. No status. If I browse on my windows laptop to the NordVPN site it says I'm unprotected so I'm pretty sure the connection isn't working for some reason...or is there something else I need to do in the Omada Controller?

UPDATE: I see what's happening. If I create a new site in the Omada Controller then I have those options in the vpn setup (username/password) but as soon as I move my ER-605 device to the new site those options disappear. Is this a bug? The ER-605 is running the latest firmware, and so is the Omada Controller.
