Configuring Port Forwarding
With A Notification Icon
You may also choose to disable logging off when a parent process terminates so that a session survives
if you close a browser. For this practice, you use a notification icon in the system tray to log out. The
icon remains until the next connection is tried. You may have to wait for the session status to update in
the system tray.
Note This icon is an alternative way to log out of SSL VPN. It is not an indicator of VPN session
status.
Detailed Steps
To enable the icon in the notification area, follow these steps:
Step1 Choose Configuration > Remote Access VPN > Clientless SSL VPN Access > Portal > Smart
Tunnels.
Step2 Enable the Click on smart-tunnel logoff icon in the system tray radio button.
Step3 In the Smart Tunnel Networks portion of the window, check Add and enter both the IP address and
hostname of the network which should include the icon.
Note If you right click the icon, a single menu item appears which prompts the user to log out of the
SSL VPN.
