Yep, DMZ and port forwarding can't be done at the same time, that's why I said alternatively.
Since you are behind a firewall, you may need to setup a domain name for your machine so you can connect.
http://2mydns.com is a decent free name service. That site will guide you through all the steps of getting setup. Once you get your domain name setup, you need to edit your HOSTS file. Do a search for that file, on 2000/XP machines its found in /winnt/system32/drivers/etc on the first line put:
127.0.0.1 yourname.2mydns.com
(With yourname being replaced with the domain name you selected when you setup the domain.) Save that file and now you will be able to connect to your own server.
Oops, I also forgot to mention that you'll need to replace all references to your internet IP of 65.173.93.89 with yourname.2mydns.com in your boot5zones.bat and loginserver.ini files.
Also, when i wrote the directions I assumed that the machine your server is running on is also the machine that you run your EQ client on. If that's not the case, then you want the EQ client's HOSTS files to look like this:
192.168.2.100 yourname.2mydns.com
