In Windows environment, you can check which ports are currently in use (already reserved by some program) from CMD commandline prompt with the command NETSTAT -A. For Windows 8.1, the operating system seems to grab ports throughout the entire numerical range. For example, with Vista and Windows7 the operating system itself usually grabs ports 49152-49158 at boot, so you can't use those ports. Note: When using a port above 49152, you always run to a risk that some other program has randomly grabbed that port before you start Vuze.

Remember to forward that port not only for TCP but also for UDP protocol, DHT needs that! (If your router is using UPnP, it should update automatically.

Go into your software firewall configuration and make sure that Vuze is allowed outgoing and incoming connections (and if there is such an option, enable Vuze to act as a server).Go to Options > Connection and input the new TCP and UDP listening port that you have chosen.If you really need to choose a port within the range 1024–49151 make sure you pick an "unassigned" port listed at the IANA port list and which is not already in use by some other application in your computer. Choose a port from the 49160–65534 range. Vuze needs only one port for the main data transfer functionality.From technological perspective there is no difference between ports, so you can select any port which is not already used by something else and then you need to configure your firewall and router accordingly. Ports are just logical addresses inside your computer's TCP/IP networking functionality.
