The system tray is the right most part of the Windows task bar. The blue circle with the question mark is Outpost Firewall's icon.
This icon is one of the primary ways you can access Outpost Firewall's many controls, settings and logs. This icon changes with each of Outpost Firewall's major polices so you can see which policy is being used to protect your system at any time. These polices are covered in Firewall Policy.
When you right-click on Outpost Firewall's system tray icon you get its context sensitive menu. You can select any of these items on this menu by clicking its name with your mouse:
Show Outpost Firewall displays Outpost Firewall's main window.
Policy opens a sub-menu where you can change Outpost Firewall's Policy to: Disable mode, Allow most mode, Rules Wizard, Block most mode or Stop all.
Optionsà displays the Options dialog window.
Always on top when selected, keeps Outpost Firewall's current window on top of all other windows.
Aboutà shows the current version of Outpost Firewall and lists each module in the package and their individual versions.
Exit Closes Outpost Firewall's GUI but leaves the firewall running in memory blocking connections and banners, etc.
Exit and shutdown Outpost Firewall Closes the GUI and stops the firewall so Outpost Firewall is no longer protecting your system.
