Outbound:
| TCP: 411 | This is the default port NMDC hubs operate on. They can also operate on any other ports in attempts to bypass ISPs who block port 411 traffic. |
| TCP: 1025-32000 | DC++ will use any outgoing port for file transfers and searches. This is the default behavior of any program establishing an outgoing connection. |
Inbound:
| TCP: 1025-32000 | Unless a port is specified in the active mode ports, DC++ will use any available port in that range for establishing file transfers. Searches are also returned from the hub on a port the client sets up (passive mode searching). |
| UDP: 1025-32000 | Unless a port is specified in the active mode ports, DC++ will use any available port in that range for returning search results |
| TCP: 1025-32000 | Unless a port is specified in the active mode ports, DC++ will use any available port in that range for SSL encrypted secure transfers |
DC++ Change Log Related Entries:
0.708: Fixed UPnP for TLS port.
0.699: Fixed TLS port not being greyed out.
0.697: TLS port change without restart fixed.
0.692: TLS port may now be specified in settings and is only opened if TLS is enabled.
0.668: Added option to use separate TCP and UDP ports.
0.20: A random free port between 1025 and 32000 is now used in active mode, unless a port has been specifically set. This port is changed on every restart to avoid problems with networks where traffic on certain ports is limited or banned.
