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.

Multi-Link PPP Configuration

Multi-link PPP (MLPPP) is a standard (RFC 1990 and RFC 1717) for inverse multiplexing, a method of combining individually dialed channels into a single, higher speed data stream. MLPPP is an extension of PPP that supports the ordering
