This solution applies to Barracuda SSL VPNs, all firmware versions.
Your Barracuda SSL VPN allows you to place restrictions on user sessions. The following options can be configured via the Advanced > Configuration page under the Session Options header:
- Maximum logon cookie age (secs): The maximum age of the cookie that is used persist the logon if the browser is closed. A value of 0 will mean that the user will have to logon everytime the browser is opened.
- Multiple sessions: This option allows you to place restrictions on users logging on more than once.
- Verify Client Address: When checking logon state, verify the remote address of the request against the address recorded at logon. This prevents re-use of logon cookies from other clients.
- Lock session on browser close: Enabling this option will force the user to provide their password upon opening a new browser and returning to the site.
