Windows Firewall
LimeWire automatically adds itself to the list of exceptions in the Windows firewall (assuming that the firewall is enabled and an exception does not already exist) when you launch the program. The Windows firewall should not need to be configured. If for some reason, you need to open up a port in the Windows firewall manually or add an exception for LimeWire, or you just want to check and make sure that LimeWire has been added, you may visit the Windows Firewall Instructions page.
