I have the same question that was asked and not answered in https://community.tp-link.com/en/business/forum/topic/523616?page=1 and the thread was closed/archived.

I'm a new user, sure, but I'm coming from a TP-Link AX55 router which can easily be set up as an OpenVPN client with NordVPN as per Nord's instructions about setting up TP-Link, but in the Omada SDN environment it's just an exercise in frustration.

I can get an OpenVPN client specification setup ok but it doesn't work (my public IP remains unchanged), then later the system deletes the setup configuration.

I hope there's an answer out there somewhere. Maybe I'm doing it wrong? Thanks for any help.
