Question about Zyxel FWA505 Nebula

I have no experience, but according to my research it should work like this:
- Open a web browser and enter the IP address of the router (usually something like 192.168.1.1).
- Log in with your admin credentials.
- Navigate to the VPN settings: In the router settings menu, look for a section labelled "VPN" or "Security".
- Configure VPN pass-through: Activate VPN pass-through for the required protocols (e.g. PPTP, L2TP, IPSec).
- Save and apply the settings: Save your changes and restart the router if necessary.
- Set up the VPN on your device: Configure the VPN client on your device (PC, smartphone, etc.) with the necessary details provided by your VPN service.
If this does not help, contacting the manufacturer directly would be helpful.
