So I'm running Win2K SP3, Limewire 1.7 (because there's fewer ads and spyware), router and firewall. I've had all of this setup for over a year and until about a few weeks ago, could connect to gnutella with no problem. So it isn't the firewall or router. I tried the telnet test and within a few seconds got the message "connection lost". My ISP is AT&T (now Comcast). Does anyone know if they're blocking gnutella or port 6346? I was going to upgrade based on the warning above, but not if I'm blocked. What's the deal with AT&T?
