The ports that BT "seed" server frequently uses are in the range of
6900-8100 such as 6969， 8000 and 7373. Therefore, we can block
this port range by creating proper rules to stop BT software from
connecting the server. However, some Non-BT "seed" servers are
also using port 8080, thus, in order not to affect other servers, we
must divide the port range of 6900-8100 to be blocked into 2
groups: 6900-8079 and 8081-8100.
The protocols that BT uses are TCP/UDP, so we need to block
both of them.
