46                        <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.
47                        If the port is forwarded, other people in the torrent can see you, thus increasing your potential number of connections, which more importantly, may increase the speed of your download.

61
62                        <p>If you share your internet connection with a router, or if your broadband modem is a router itself, then you will need to forward Transmission's port by following the instructions below.
63                        In addition, if you have enabled the Mac OS X firewall, you will need to open a port in that too. See below for details.

117                                <li>If you don't use a router, that is, your modem is directly connected to your computer, you'll need to open Transmission's port in the Mac OS X firewall. For instructions <a href="pffirewall.html">click here</a>.<br>

123                        <p>Keep in mind that many DSL modems also function as routers, and hence port forwarding as per above may still be necessary, even though your computer is directly connected to the modem.
