27                        <p>You haven't port forwarded correctly. Port forwarding opens a port in your firewall or router so that incoming connections from the outside world can be made with Transmission.

36
37                        <p>Transmission uses a single port for all the torrents you are downloading. If the port has not been opened (ie forwarded) that means only you can make connections to others in the swarm.
38
39                        If the port is forwarded, others can connect to you, thus increasing the potential number of people connected to you, and more importantly increasing the speed of your download.

77                                NB: it is highly recommended you enable the Mac OS X firewall if you are not using a router.</li>
