Radius Client Configuration - NETGEAR UTM9S Reference Manual

RADIUS Client Configuration

Remote Authentication Dial In User Service (RADIUS, RFC 2865) is a protocol for managing
authentication, authorization, and accounting (AAA) of multiple users in a network. A
RADIUS server stores a database of user information and can validate a user at the request
of a gateway or server in the network when a user requests access to network resources.
During the establishment of a VPN connection, the VPN gateway can interrupt the process
with an XAUTH request. At that point, the remote user needs to provide authentication
information such as a user name and password or some encrypted response using his or her
user name and password information. The gateway then attempts to verify this information
first against a local user database (if RADIUS-PAP is enabled) and then by relaying the
information to a central authentication server such as a RADIUS server.
