Answers will vary. By default, most apps are blocked by Windows Firewall. You may be required to make firewall changes to allow some apps to function correctly. Other times, you might need to open a specific port to get an app to function correctly. For example, to play a multiplayer game with friends online, you might need to open a port for the game to that the firewall allows the game information to reach your PC.
