Question:
Why 2FA auth page not automatically appear when using OpenVPN Connect?

Answer:
The automatic display of the 2FA authentication page after a VPN connection is a feature specifically integrated into the Zyxel VPN Client (SecuExtender). Third-party VPN clients, such as OpenVPN Connect, do not have this built-in functionality.

For Zyxel VPN Client (SecuExtender): The 2FA authentication page will automatically open in your web browser after a successful VPN connection.
For Other VPN Clients (e.g., OpenVPN Connect): You must manually open a web browser and navigate to the authentication URL after establishing the VPN connection. The common format for this URL is http://yourdeviceip:8008, where yourdeviceip should be replaced with the actual IP address of your Zyxel device. Ensure that port 8008 is allowed from WAN to the device in your security policy.
