Cannot connect with one computer on my network

[usmaak]

Hi,

I have two computers running on my network, both updated with the latest Java and Limewire. Both computers have CA Antivirus on them and no firewall (for testing purposes). I have a Linksys WRTSL54GS router between my DSL modem and my computers. Both connections are done wired. The router does not have UPNP enabled. I have no ports forwarded, and my one computer works just fine. On the other computer, I've tried varying combinations of everything I can think of and nothing works. I just cannot get a connection, no matter what I do. Both computers have the latest Windows XP SP2 updates. I checked port 6346 through the limewire website, and it had no problem connecting there. When I check bug reports, it shows IsConnected = False. I checked to see how it was setup, and it is set up for port 6346 for manual port forward and listening port. Right now I also have this computer set up with a static IP of 192.168.1.51, and have ports 6346 - 6349 forwarded to it.

When limewire tries to connect, I check the connection tab. It is just running through attempts at connecting to different IPs, but not a single one is connecting. I took a look through netstat and got the following:

TCP 0.0.0.0:6346 0.0.0.0:0 LISTENING
UDP 0.0.0.0:6346 *:*
UDP 0.0.0.0:6347 *:*

Limewire used to work fine on this machine. Something's happened to make it stop working fine.

Any help or ideas on stuff I can try would be very much appreciated.
