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:
Item Description
Enable
Check to enable RADIUS client feature.
Server IP Address

Destination Port
The UDP port number that the RADIUS server is using.
The default value is 1812, based on RFC 2138.
Shared Secret
The RADIUS server and client share a secret that is used to
authenticate the messages sent between them. Both sides
must be configured to use the same shared secret. The
maximum length of the shared secret you can set is 36
characters.

Re-type the Shared Secret for confirmation.
After finished the above settings, click OK button to save the settings.

server which performs security authentication by itself. This page is used to configure settings
