Different port status amule-transmission
Dear friends: I've configured gufw in order to open ports 4662 and 4672 for amule (so I solved a low ID problem). For Transmission it wasn't necessary to configure any rule. The matter is that testing specific ports with ShieldsUP, amule's port 4662 appears as "open" or "closed" depending on amule is working or not, while all the Transmission's ports appears as "Stealth" whether the program is open as if it's closed. What can be causing this different behavior? It's more curiosity than paranoia, since I feel white safe with my ubuntu plus Gufw ;-)
Thank you very much in advance.
