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.
