Allowed Hostnames work similarly to Allowed IP Address entries, except they are configured by hostname instead of IP address. A daemon periodically resolves the hostnames to IP address(es) and allows them through the portal without authentication in this zone.
The most common use of this feature is to make a “walled garden” style portal, where users are permitted to access a restricted set of sites without authenticating to the portal. This is also commonly used with the Pre-authentication Redirect URL if that page is hosted externally.

Allow traffic sourced from this hostname through the portal, such as the hostname of a local client attempting to reach the Internet.
Allow traffic both to and from this hostname.
