2.13.1. Web Redirection
The IWE3200-H supports both IEEE 802.1x-based and Web redirection-based user authentication.
Here is a brief description of how Web redirection works: When an unauthenticated wireless user is
trying to access a Web page, a logon page is shown instead of the requested page, so that the user can
type his/her user name and password for authentication. Then, the user credential information is sent
to a back-end RADIUS (Remote Authentication User Dial-In Service) server to see if the wireless
user is allowed to access the Internet. The authentication mechanism employed for RADIUS is
EAP-MD5, PAP, or CHAP.
