Comment 11 for bug 264950

I think this should be reconsidered by the Vuze development team. I know Ubuntu's bug tracker is not the best place to try and get their attention, but it's worth a shot.

You can read my (slightly ranty and undeservingly infuriated) post here: http://ubuntu-ky.ubuntuforums.org/showthread.php?p=8653035#post8653035

Basically, using the Registered or Well Known ports is not a good idea. For me it isn't even an option.

Eventually, if ISPs pick up too much traffic on the wrong port, they'll just shut the port down--no matter what purpose it should be open for--and if they have to do it enough times, they'll shut it down permanently and then they'll disable it by default. This is bad news for legitimate services that should be running on the Well known and Registered ports. It also means you could potentially DOS your own computer by specifying the same port in Vuze that is used by another service.

Furthermore, certain types of internet connections don't allow the use of Registered ports, like mine: tethering through a cell phone. I imagine the reason for this is that the cellphone itself would never make use of the Registered ports, so they've been closed. In my case, one of the dynamic ports is open, but it is over 49152 so I can't set it in Vuze.
