To open Outpost Firewall's miscellaneous options window:
Go to Options menu
Click General.
In the Miscellaneous area of the dialog is where you can select or deselect to have Outpost Firewall start automatically whenever your computer first starts. Select Minimize to System Tray to not have a button placed on the task bar for Outpost Firewall's main window whenever it is minimized. Instead of this, to see Outpost Firewall's main window, simply double-click on its system tray icon or right click on it and select Show Outpost Firewall.
If Close button minimizes, not exits interface is selected, then whenever you click on the close button only Outpost Firewall's dialog window will close, not the firewall. In this case, to close Outpost Firewall, right-click on its system tray icon and select Exit or Exit and Shutdown Outpost Firewall.
Select Apply rules without need of interface (available only in Outpost Firewall Pro. See Benefits of Outpost PRO) if you want Outpost Firewall to run in invisible mode, without its system tray icon or any of its dialog windows. This option is provided for two reasons: to save system resources and for a parent or Systems Administrator to block unwanted traffic or content in a way that's completely hidden from a user. In order for this option to take effect, you must disable the Run automatically at boot-up option.
