    By default access is allowed on "private" networks, such as your home or work network. If you also want to allow access on "public" networks, such as you would find at a coffe shop or airport, you can also click the check box for "public".
  8. Click on the OK button. You can then close the Windows Firewall window. You should be able to connect to whatever port or ports the application opens now from another system on the same local area network (LAN).
