Well today i figured out my problem with my limewire connection issues. I discovered this when i went to trace an IP address of a friends website and i wasn't getting any results past my network.
Basically what was happening was Visual Route was saying that packets were being lost past hop 2 and that there was insufficient cached data to determine what the next hop should be. I thought this to be odd since my visual route app has never had any problems. I thought that it might just be the site. so i tried others with the same result. So i went to visual route site and read the firewall configuration help page. I discovered that my 2WIRE router was blocking ICMP packets from passing into my network. But my router does not have the option of ICMP so what i did was check the all other protocols box and voila my visual route app worked fine.
I then got a hunch to try limewire and low and behold it worked. Connected to 3 ultrapeers right away and had no problems finding files.
So i don't think that limewire uses the ICMP protocol but it must use some other protocol that my router was blocking under the other protocols category. So go figure. I posted a screen image if anybody is unsure of where to go to set this up in the router. Does anyone know what protocol limewire uses. Maybe other users are having the same problem but have s/w firewalls and would need to know what protocol to unblock!!
HOPE THIS HELPS ANYONE
