Ok, I think I have it. Only services are associated with individual ports. (e.g. I connect with a web server on port 80, but it could use any port above 1024 to communicate back to my computer). In the instance in question, the traffic came from port 6000 of the "sending" computer, but this was not tied to any service. It was only the port which the sending application was using. It could have been port 10200 for that matter. Ok, I'm still learning.
