RADIUS Configuration
RADIUS is an authentication protocol where passwords are stored on a RADIUS
server. RADIUS allows large numbers of passwords to be stored in a centralized
location. Before instituting RADIUS, please setup and install a RADIUS server on
the LAN.
Items in the above submenu are described as follows:
•
RADIUS State – Enables or disables RADIUS. When enabled, all settings in the
Dial-in User Profile are disabled.
•
Type – Refers to the type of external password protocol. Currently, only
RADIUS is supported.
•
Server IP Address – This is the IP Address of your Unix- or NT-based RADIUS
server.
•
Port – The port number for the RADIUS server. The standard port number
specified by RFC 1700 is 1812 (shown above).
•
Key – This is a shared secret used to identify the router as a valid RADIUS client.
The RADIUS authentication service works for dial-in users only. Thus, when
RADIUS is enabled, passwords for dial-in users will no longer be checked in the
dial-in user profile. Instead, the authentication request will be passed on to the
RADIUS server. Remote networks (routers) dialing into the router will still be
authenticated using the remote network profile.
