It's probable, but I don't think you'd be able to connect if it was the case. I would try another P2P using Gnutella just to confirm the trend. I recommend you trying Bearshare Lite (no spyware, no adware)

(out of context, this is the first time in 3 years that I see that you can attach a file with Gnutelllaforums as the host.... I always used my webserver to post images... I feel shame for myself
