Hello, Thanks for reaching out to us. Unfortunately, the VPN is not currently ready for manual configuration, either for use in a separate application or at the router/modem level. It requires the Mozilla VPN application to work. I'm sorry for the inconvenience. The Mozilla VPN is compatible with Windows 10 (64-bit only), macOS(10.14 and up), Android (version 8 and up), iOS (12.0 and up), and Linux (Ubuntu-only) devices. You can have up to 5 devices on a single subscription. Let us know if we can help with anything else. Thierry
