The first thing I need to know is did you follow the instructions exactly as they are listed in the link below. And if you have your router set to manual port forward then that is what you should have LimeWire set on also. You should also set LimeWire to listen on the same port you set your router to. If you look at the bottom of the picture you will see what birdy was asking about are others able to upload from you. If your router has UPnP then use UPnP no matter what you set your router for set LimeWire for the same.
If you set your router for UPnP and LimeWire for UPnP then LimeWire will choose the port don't worry if it isn't 6346 LimeWire will choose the best port for it.
