found another test-- http://www3.limewire.com:6346/

I expect it should show you "Your test page was a success!" and will mean that you at least have a route through port 6346

btw--when you removed all old limewire traces, I'm guessing you also removed the LimeWire folder from ~/Library, right? email me and I'll send you my gnutella.net file (it has a good list of connections for startup).
