TP-LINK Archer AX20

[-IceMan- 1]

Hi, I need step by step help to setup VPN client mode on a TP-LINK Archer AX20, with OpenVPN protocol. I have already purchased subscription and created 2 ports. I need to bypass CGNAT and port forward my security system to be able to access it from anywhere. I have already create a router file but it can't connect.
I need to know if my router is 100% compatible with your service and can be setup for remote access to my security system. Thank you in advance.
