l External captive portal— For external captive portal authentication, an external portal on the cloud or on
a server outside the enterprise network is used.
Walled Garden
The administrators can also control the resources that the guest users can access and the amount of
bandwidth or air time they can use at any given time. When an external captive portal is used, the
administrators can configure a walled garden, which determines access to the URLs requested by the guest
users. For example, a hotel environment where the unauthenticated users are allowed to navigate to a
designated login page (for example, a hotel website) and all its contents. The users who do not sign up for the
Internet service can view only the “allowed” websites (typically hotel property websites).
The administrators can allow or block access to specific URLs by creating a whitelist and blacklist. When the
users attempt to navigate to other websites, which are not in the whitelist of the walled garden profile, the
users are redirected to the login page. If the requested URL is on the blacklist, it is blocked. If it appears on
neither list, the request is redirected to the external captive portal.
