Port defaults

I think it's best that no firewall is applied by default. For example, a
firewall on each computer of a home network would be an unnecessary
complication, as a firewall at the router provides sufficient security
for the whole network in most cases.

I am not sure about your Azureus / Vuze problem, but I would think it's
a problem specifically with that program. Since ports are open already,
there is no need to "reset" or "re-open" them. If you want to use a
firewall to have ports closed by default, you use use ufw (uncomplicated
firewall) which is very simple to use and set up rules for. There is
even the gufw GUI available for it.

If you're after an easy to use torrent program, you might be better off
with Transmission, which is the default now for Ubuntu installations.
Hopefully that won't have the same strange port issues.
