It wouldn't be there if Limewire wasn't restricted at all. The brickwall means that you are not recieving incoming.

Try backtracing your steps for portforwarding Limewire (I bet you'll find some small mistake).

I forgot to mention that you need to forward both TCP and UDP for the port. If you managed to portforward to Azureus, then I really don't understand why you're having trouble doing the exact same thing for Limewire.
