2.6. Configuring Authentication Settings
The SMCWHSG44-G supports both IEEE 802.1x-based and Web redirection-based
user authentication.
Here is a brief description of how Web redirection works: When an unauthen-
ticated 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 or checked against the built In Local Authentication database in the
Wireless Hotspot Gateway to see if the wireless user is allowed to access the
Internet. The authentication mechanism employed for RADIUS is EAP-MD5,
PAP, or CHAP.
