Each license comes with two geographically redundant servers for RADIUS Authentication and RADIUS Accounting. We will create these as close as possible to your physical location based on the data-centers we have available.


You can configure UniFi in two ways. Using an external Captive Portal to authenticate user or using WPA-Enterprise. Use the correct steps for each mode.


This option will present users with a splash page. It relies on your WiFi network to be open or to use a shared WiFi password. When users connect to it and open their browser, they will presented with a login screen where to type their email and pincode to connect to your network. You can also configure this appliance to use Enterprise Authentication using the instructions in the next section below.


  1. Provide the public IP of your UniFi controller. The RADIUS servers need to be able to directly connect to  your Controller (SW, Cloud Key) to authorise connecting devices. Controller URL is usually in format like this https://your_public_static_ip:8443. Make sure it is the PUBLIC IP address and it's reachable through the Internet (not internal address like 192.168.*.*, 172.16.*.*, or 10.*.*.*). You might need to configure port forwarding on your Internet router and firewall. If you are not sure, please consult with your ISP provider. This article may help you doing this.
