Sul wiki ho trovato un modo per verificare se le porte sono aperte e dopo averlo avviato mi è apparsa questa scritta:
"Error: TCP port 4662 is unavailable. Make sure your firewall or router is allowing/forwarding this TCP service port and your ED2K client is running (i.e. aMule, eMule).
Detailed Error Message
TCP Error 110 Connection refused
Explanation
The connection timed out, meaning the port is being blocked or incorrectly forwarded by a firewall or your computer is turned off
