Guest access – Mist Cloud

In this topic, you will learn how to configure Mist Cloud to work together with the Portnox™ Cloud captive portal for guest user authentication.

Before you begin configuring your access point, you must configure the guest network in Portnox Cloud and note down the values of the fields: IP (for walled garden), Captive Portal URL, and Shared secret.

Important: This guide provides general instructions for integrating Portnox Cloud with specific third-party devices. While we aim to provide helpful examples for commonly used models, configurations may vary across manufacturers, models, and environments. As a result, we cannot guarantee that these steps will work in every scenario. For questions or issues related to RADIUS setup – which is an industry standard and not specific to Portnox – or device-specific settings and troubleshooting, we recommend consulting the device manufacturer’s documentation and contacting their support team. While Portnox Support is happy to assist where possible, please note that detailed configuration of third-party devices is typically best handled by the manufacturer.
Warning: This topic contains documentation prepared by our support agents more than 12 months ago. It may not cover the newest models or the newest interfaces of NAS devices. We’re working on bringing you updated documentation for NAS devices in the near future. However, the methods of setting up third-party devices may still change when the manufacturers update their firmware or release new models.
