This page explains the configuration of SonicWall devices to work with IronWiFi Captive Portal.

  2. DHCP and DNS are appropriately configured.
  3. IronWiFi initial setup is complete. This setup includes Network and Captive Portal settings.
  4. SonicWall Access Point can communicate with IronWiFi servers.

The last step is to Allow remote connections on your Firewall. IronWiFi needs to be able to connect to the SonicWall Guest Services to authorize connected clients. Guest Services are listening on port 4043 and IronWiFi will try to connect to the URL in this format:


  • SOURCE_IP_ADDRESS - IP address that we have received the authentication request from

We will be connecting directly from the web server, so no further changes are required in your SonicWall firewall rules.\

! You must also install a valid SSL certificate on your controller/AP, in order to avoid authentication issues !

Common Errors

IronWiFi needs to be able to connect to your Access Point to authorize the connecting device. If not successful, the Captive Portal will return different error codes in the error_message parameter.

  • sonicwall_gw_connection_failed - our servers could not connect to your SonicWall AP. Make sure the Access Point Guest Services port is reachable over the internet, check your firewall settings and port forwarding rules if necessary. The Guest Services service is listening on port 4043/TCP by default, and you can override this value using the Controller URL parameter in the Captive Portal settings in our Console.
