Authentication for a VNS
7.2.1 Authentication for a VNS for Captive Portal
For Captive Portal authentication, the wireless device connects to the network, but can only
access the specific network destinations defined in the Non-Authenticated Filter (see Section
7.5.2, “The non-authenticated filter for Captive Portal”, on page 92). One of these destinations
should be a server (either internal or external) that presents a web page logon screen (the
Captive Portal). The wireless device user must input an ID and a Password. This request for
authentication is sent by the HiPath Wireless Controller to a RADIUS server or other
authentication server. Based on the permissions returned from the authentication server, the
HiPath Wireless Controller implements policy and allows the appropriate network access.
There are three mechanisms by which Captive Portal authentication can be carried out:
● internal Captive Portal: the HiPath Wireless Controller presents the Captive Portal
webpage, carries out the authentication and implements policy
● external Captive Portal: after an external server presents the Captive Portal webpage and
carries out the authentication, the HiPath Wireless Controller implements policy
● external Captive Portal with internal authentication: after an external server presents the
Captive Portal webpage, the HiPath Wireless Controller carries out the authentication and
implements policy
Captive Portal authentication relies on a RADIUS server on the enterprise network.
