of a VPN connection, the VPN gateway can interrupt the process with an XAUTH request. At that

or some encrypted response using his 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.
To configure primary and backup RADIUS servers:
1. Select VPN > IPSec VPN from the menu. The IPsec VPN submenu tabs appear with the IKE
Policies screen in view.
2. Click the RADIUS Client submenu tab. The RADIUS Client screen displays.
