Testa porta (port tester)

Port test - It is a tool that you can use to check your external IP address and detect open ports on your connection. This tool is useful to find out if your port is configured correctly or if your server applications are being blocked by a firewall to make it easier to diagnose any failure in the external connection of your applications, websites, games, etc ...

For the test to reveal that a door is open, the following conditions must be met:
- Your router must be configured to port forward (port forwarding) to the computer in question.
- If there is a firewall, it must be configured to allow connections to the respective port, or alternatively, turn off the firewall.
- Some program will have to be listening to the door in question in order to answer our test.
