Configuring Extended Authentication (XAUTH)

When connecting many VPN clients to a VPN firewall, 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 firewall 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 can be enabled when adding or editing an IKE Policy. Two types of XAUTH are
available:
• Edge Device. If this is selected, the VPN firewall 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.
• IPsec Host. If you want authentication by the remote gateway, enter a User Name and
Password to be associated with this IKE policy. If this option is chosen, the remote gateway
must specify the user name and password used for authenticating this gateway.
Note: If a RADIUS-PAP server is enabled for authentication, XAUTH will first check the
local User Database for the user credentials. If the user account is not present, the
VPN firewall will then connect to a RADIUS server.
