The blue notification window appears every time if an application tries to connect to the Internet without subjecting to rules. Depending on whether there┤s a outgoing or incoming connection, you are asked for permission. You will receive detailed information about the application. If you like to apply the setting for all ports (only experts mode), please mark the checkbox to the left of it. If you like to add the access of the application as a rule, so that the notification window is indicated with the next connecting attempt of this application no more, please mark the appropriate checkbox. You can edit the rules subsequently.
