Conclusion: Healthy Setup! We could detect no interesting responses from any of the commonly probed TCP and UDP ports. It would be difficult for an attacker to know where to start without further information.
Key
Key:
OPEN PORT
a port, or ports, appear to offer a possibly vulnerable service All services should be closed unless you require them to be open
CLOSED PORT
a port, or ports, are responding that they are closed A software or hardware firewall can eliminate all responses and 'stealth' your IP completely, if you so desire.
FILTERED PORT
the port is silent in response to open-port requests No response to probes were detected.
