Remote Authentication Dial-In User Service (RADIUS) is a security authentication

client/server protocol that supports authentication, authorization and accounting, which is

widely used by Internet service providers. It is the most common method of authenticating

and authorizing dial-up and tunneled network users.

The built-in RADIUS client feature enables the router to assist the remote dial-in user or a

wireless station and the RADIUS server in performing mutual authentication. It enables

centralized remote access authentication for network management.

Vigor router can be operated as a RADIUS client. Therefore, this page is used to configure

settings for external RADIUS server. Then LAN user of Vigor router will be authenticated by

such server for network application.

Available settings are explained as follows:
