WINDOWS XP INTERNET CONNECTION FIREWALL:
Within LimeWire, go to: Tools -> Options -> Advanced -> Firewall Config
Make a note of the Listening Port located in the box next to "Listen on Port"
Go to Start -> Control Panel
Open Network Connections
Right Click on the connection you use to connect to the network
Choose Properties
Go to the Advanced Tab
If your Firewalled is Enabled go to step 10
If you want to enable Windows XP Firewall check the box (this will enable the "settings" button. If you are not interested in enabling your Windows XP Firewall, hit cancel -- LimeWire will not be affected, and you may stop following these instructions.
Under Windows Firewall Options, Go to the Advanced Tab.
Select Internet connection used. (Local area network or the name of your connection)
Click the Setting button
Click the "Add..." button
In the description field add "Gnutella"
Set the IP address to "127.0.0.1"
Check the TCP Radio button
Set the external and internal ports to the same port that you made a note of in step 2
Press OK
Repeat steps 13 to 16, except this time check the UDP radio button in step 16
Make sure the list of services has two items listed Gnutella, and make sure they are both checked.
Click OK

there is still a problem.

And i have one firewall and if i disable it, my limewire still just says starting connection. I have no idea whats wrong. I did what you told me. is there any other way?
