You can require that users log on after interruptions such as when acomputer comes out of hibernation or standby, when the user switches to a different wireless network,or when a connection is forcefully closed.NoteNote: The Firebox SSL VPN Gateway attempts to authenticate users using the cached password. If userslog on using a one-time password, such as used by an RSA SecurID token, authentication on the FireboxSSL VPN Gateway fails, and the user can be locked out and unable to log on.To prevent the use of one-time passwords, the Firebox SSL VPN Gateway can be configured to forceusers to log on again after a network interruption.
