I've had the same experience. I can, and always have been able to recieve files via P2P LimeWire, but apparently no one is able to reach my 'puter to upload my shared files. It has been pointed out to me on this forum by helpful readers that I may need to make a STATIC IP for my router. I haven't done this yet because I have a tenant who uses the same router for his IP's and I am reticent to mess with anything that might mess his connection. In the mean time I do feel a twang of guilt for not making myself available for uploads. If there was/is a way to make this possible witout having to have a static IP, I'd like to hear about it.

As for your problem. Are you using a router? Is there a router support page that can help you with opening ports on the router from it? Have you looked at the website portforward.com?
