Extended Authentication (XAUTH) Configuration

When connecting many VPN clients to a VPN gateway router, an administrator may want a unique
user authentication method beyond relying on a single common preshared key for all clients.
Although the administrator could configure a unique VPN policy for each user, it is more
convenient for the VPN gateway router to authenticate users from a stored list of user accounts.
XAUTH provides the mechanism for requesting individual authentication information from the
user, and a local User Database or an external authentication server, such as a RADIUS server,
provides a method for storing the authentication information centrally in the local network.
XAUTH is enabled when adding or editing an IKE Policy. Two types of XAUTH are available:
• Edge Device. If this is selected, the router is used as a VPN concentrator where one or more
gateway tunnels terminate. If this option is chosen, you must specify the authentication type to
be used in verifying credentials of the remote VPN gateways: User Database, RADIUS-PAP,
or RADIUS-CHAP.
