Then the panel with information about the availability of the specified port and the external IP of the computer will be displayed.

Opening ports

Modern operating systems and various security software come with firewalls that provide protection against external attacks. In the process, they rely on various rules for installed applications. Before scanning, it is necessary to go into the parameters and open outgoing and incoming connections. This will avoid problems at the stage of connecting to an external network. After testing, the program will offer to automatically open the port if it turned out to be closed. An additional warning will be displayed, which the user should agree to. Then you can launch the application and check the correctness of Internet access. If there are difficulties with the configuration, it is recommended to study the help section.
