Order is of no consequence.

DHT is a security hazard - dangerous to *you* - and some private 
trackers demand that DHT be disabled. It's a slightly complicated 
procedure to disable DHT in Azureus. Some private trackers provide a 
howto, again, in their FAQs or support forum. I can provide the info, if 
needed.

Additionally, you may want to install the SafePeer plugin.

Most trackers blacklist the BT default port because the majority of ISPs 
block it and many others these days. The tracker FAQ usually says so.

You can test if your system is connectible at NatCheck:
http://btfaq.com/natcheck.pl
This will verify that port forwarding is set up correctly.
Unfortunately the service is frequently down. Like now.

Your port can also be tested at Gibson Research's "ShieldsUp!":
https://www.grc.com/x/portprobe=<port number>,
where <port number> is the port that you are using for your BitTorrent 
data. If it reports that the port is "Open", then your port forwarding 
is working okay. If it reports that the port status is "Stealth" or 
"Closed", then the port is not open and your system will not be 
connectible for BitTorrent communications.

http://www.portforward.com has detailed information on setting up port 
forwarding for a large number of different routers and it also has 
information on setting up a static IP address in your computer.

To find out if you're behind a (transparent/anonymous) proxy, try 
ProxyJudge: http://proxyjudge.org/
It lists the HTTP headers that the server where it is running received 
from you. The relevant ones are HTTP_CLIENT_IP, HTTP_X_FORWARDED_FOR and 
REMOTE_ADDR.

This is really weird :-\

Quite common, actually.

Welcome. Good luck.
