I don't visit this site as often as I used to, so I did not see this post. There also is a section on the TRX website titled "Generic Networking info (useful for any server application)." Take a look there. Getting the system to work over the internet is not exactly a beginner's task, but it is VERY possible. Just take your time and don't give up. I'd say just see if you can get it going via local network at home first.
Thank you to the other posters for offering help. I do appreciate it.
