I've been playing with this thing and have found one anomaly in the Azureus
NAT/Firewall test. The Azureus client first establishes an HTTP connection
(port 80) to a remote host. The remote host then attempts to establish a TCP
connection back the the originator of the HTTP connection. This of course
can go stupidly wrong if there is an HTTP proxy.
