TPG Internet uses a transparent proxy on port 80 for HTTP communications. This transparent proxy can cause problems when using BitTorrent. When you download a torrent, your client communicates with the torrent tracker, and the tracker tries to determine your IP address. If the torrent tracker is running on port 80 the communication is going through TPG’s transparent proxy and the tracker will most likely detect the IP address of the transparent proxy instead of your IP address (some trackers are smarter and can still detect your correct IP). The way this issue is resolved is by setting up your client to send your real IP address to the tracker. Some trackers however, can reject this IP address so it is not a 100% foolproof method (Although the failure is very low).

If the tracker does not have your correct IP address, it will cause problems with connectivity to other peers. The tracker sends the IP address it has out to other peers, so that they can connect to you remotely. Being not “connectable” like this will result in much slower downloads.

The point of setting up the DynDNS is so that Azureus can resolve the hostname you setup to get your IP address (only nessescary if you have a dynamic IP), and then Azureus can pass the IP onto the tracker.

If you are sceptical about if this works, or not sure if you should you be bothered, try this test torrent beforehand. I can almost guarantee that it will work much better after you have setup everything according to this guide.
