Another firewall question!

I get people attempting access to my computer (through port 6346) a whole lot nowadays -- long, long after I shut down LimeWire, even if I shut down while no uploads are ... uploading. I mean TONS of attempts, like 50-100 every ten minutes. Coincidence? I mean LimeWire uses 6346 and ... well I had Norton running before and I never got anywhere near the number of access attempts, and the few I got were not all 6346 attempts.

Thoughts? Ideas?
