Next, you will need to modify two html on the controller so that it correctly redirects and authenticates. First of all, download the below two files:
Open the index.html file in a text editor (right click on the file and choose your favorite text/code editor) and at the top of this document you will see an item named "splashurl", edit this so that it shows:
!This has been done automatically if you opened these instructions from the ironwifi console!
var splashurl = get this value from the IronWifi console
(Click "Network" -> Captive Portal.
Under "Portal Settings" header -> "Splash Page URL") ;
Now, as a root user, you need to copy these two html files to your UniFi controller Hotspot directory. This is typically located at the below location. If you are using multiple sites, replace the string "default" with your side identifier which can be obtained from the Unifi controller address bar:
- Windows: C:\Users\\Ubiquiti UniFi\data\sites\default\app-unifi-hotspot-portal
- MAC: ~/Library/Application Support/UniFi/data/sites/default/app-unifi-hotspot-portal
- Linux: /usr/lib/unifi/data/sites/default/app-unifi-hotspot-portal
- UDM Pro: /data/unifi/data/sites/default/app-unifi-hotspot-portal
- CloudKey: /srv/unifi/data/sites/default/app-unifi-hotspot-portal
To upload those two files to your controller, you will need an FTP client such as https://winscp.net/ or https://filezilla-project.org/ for macOS/Linux users. This software will enable you to connect to your controller and manipulate with its file system easily.
(replace default in the folder structure with your site name if different)
If the sites folder is not present, you can created it by simply uploading a floorplan (even a dummy one if required) in the UniFi controller which will create the folder you need.
[CloudKey Users: Having trouble finding your CloudKey IP for the FTP? Under the UniFi console, on the first page where you select your controller, switch from grid to table view, and your devices IP address will be displayed. Enter that with the file path in your FTP to upload the file.
Additionally, if your FTP is not directing you to the proper folder in the UniFi console to upload the Index.html & auth.html files, do not enter a mount path, and manually navigate to the correct folder.
SSL Certificate installation
Finally, you will have to purchase and install a valid SSL certificate on your controller and this certificate needs to have a unique common name - for example unifi.example.com
An SSL certificate can only be purchased for a domain, therefore, you will need to alter your DNS records so that this hostname resolves to the IP address of your controller, for example: unifi.yourdomain.com -> 192.168.1.10
! You must also install a valid SSL certificate on your controller/AP, in order to avoid authentication issues !
There are a lot of articles and videos about this topic, here are some:
Another guide on how to install an SSL certificate on Ubiquiti Unifi can be found here - https://www.namecheap.com/support/knowledgebase/article.aspx/10134/33/installing-an-ssl-certificate-on-ubiquiti-unifi/
After uploading the SSL certificate to your controller, you need to switch on the "Use Secure Portal" and "Redirect using hostname" options and enter the hostname from the SSL certificate, for example unifi.example.com
Click Settings -> Guest Control -> Under "Guest Policies" header -> enable "Use Secure Portal" and "Redirect Using Hostname"
