This section allows you to configure the wireless captive portal settings for wireless clients to access your wireless network. If enabling captive portal settings for wireless access, the recommended mode for creating a basic customized captive portal web page with authentication options and redirect URL to a specific website without an external server is the Internal Captive Portal mode. The Redirect URL mode will simply redirect your wireless clients to specific website upon connecting without any required authentication. The Captive Portal with Radius mode will require the setup and configuration of an external server for authentication and web page customization.
