What do I need?

Before you configure this appliance, you will need a RADIUS Server license. You can reach out to to obtain one.

  1. Once you have the license, paste it in Space Settings > Integrations > Radius

  2. Save the settings and then click on "Manage Radius Servers".
  3. Click on "Add Radius Server" and give it a meaningful name and a description. Choose the correct appliance vendor

  4. Once the server is created you can access its details to get the IP addresses, port numbers and secrets to used in the configuration of the appliance below.

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.

Configuring Aruba Controller

This page explains basic configuration for Aruba Virtual Controller and external Captive Portal with RADIUS authentication.

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.

  1. Sign-in to the Aruba Administration console usually available at


  2. Navigate to Network -> Edit and open configuration settings of a network that should be protected with a Captive Portal with RADIUS authentication - aruba qa in our example.


  3. Configure Client IP & VLAN Assignment. In our example, we keep the default settings.

    • Navigate to the Security tab and configure Security Level:

    • Splash page type: External

    • Captive portal profile: qa in our example

    • Auth server 1: qa in our example

    • Accounting: Use authentication servers

    • Encryption: Disabled

  4. Click on the Edit button next to the Captive portal profile and enter values from the IronWifi console:

    Type: Radius Authentication
    IP or hostname (XYZ is the subdomain of your account as found in System > Spaces > your space name > Web Address.)
    URL: /en/splash
    Port: 443
    Use https: Enabled
    Captive Portal failure: Deny internet
    Automatic URL Whitelisting: Enabled
    Redirect URL: empty

Click on the Edit button next to the Auth server 1 and enter values from the IronWifi console:

IP address: in our example
Auth port: 5701
Accounting port: 5702
Shared key: xxxxxxxxx


Click on the Walled garden link and enter values from the RADIUS server.

White list: all IP addresses and host-names below, including


By default, Aruba controller will intercept HTTPS traffic to all external servers breaking SSL connections. To prevent this, we need to create new Role permitting TCP connections to port 443 on external servers -,, etc.

allow https

Enable the Assign pre-authentication role and select create role. Click on the Finish button to apply new settings.


To fix the SSL error, you will need to replace default invalid certificate.

You can generate a valid SSL certificate for free on this URL - You can let the page generate a certificate signing request for you, or visit the following page for detailed instructions on how to generate a request manually - Don't use a wildcard SSL certificate.

Copy content of downloaded files certificate.crt, ca_bundle.crt and private.key to a single file (aruba.pem).

Upload this file to your Aruba IAP - click on Maintenance -> Certificates.

Certificate type: Captive portal server certificate

Certificate format: PAM

Click on the Upload Certificate button to apply new settings.
