3.6. Configuring Authentication Settings
All models of the access gateway support Web redirection-based user authentication. Furthermore, the
advanced edition of the wireless access gateway, which has a built-in access point, supports IEEE
802.1x-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.
TIP:
For IEEE 802.1x-based user authentication, see Section 3.5.2.3.

Fig. 78. Web redirection enabled with authentication.
There are three modes for Web redirection— Enabled with Authentication , Enabled without Au-
thentication , and Disabled .
In Enabled with Authentication mode, you specify the RADIUS authentication method that cor-
responds to your RADIUS server settings. Currently EAP-MD5, PAP, and CHAP are supported. And
you can choose the way username and password information from clients is encrypted:
