What it's for: Check whether a TCP port is open on any host, from outside your network. Test common services or any custom port. Instant.
What trips people up: My service runs but the port shows closed — why? Either a firewall is dropping the traffic, the port forward is missing, or the service is bound to localhost instead of all interfaces.
