Choosing a port
Azureus only needs to have one port open to the internet, while the original client (and others) need a whole range of ports to be open. The default port in Azureus is 6881, however we will be changing our ports to a random number as some trackers block default ports.
The first thing we will do then is choose our port that we are going to use. Just choose a random number preferably between 49152 and 65535. You should definitely not use any of these following ports: 411-413, 1214, 4662, 6346-6347, 6881-6889. Write down the port you are going to use
