Another piece of info is that I'm running Limewire 2.2.3 Pro.
Also note that I am able to get a autoconnections established and I've seen that Limewire netstats shows over 1000 hosts sometimes. I've also been able to successfully download files recently. So I don't think my problem is my network setup.

I just rechecked my limewire statistics and it reports that there were 5 uploads so if this means there were 5 successful uploads then perhaps some people are able to upload from me but from what I can tell from watching the monitor view the vast majority of uploads are failing with a transfer interrupted message (this is leaving my system up on the net for 24 hours).
