Why not simply port forward a separate port for each of LW, Aquisition & Azureus. I don't understand your UPnP settings since my device doesn't support such. And port forwarding is more reliable in any case. Steps are ... 1. set up a static ip. 2. Forward a port. 3. Set LW appropriately; Manual port forward instructions & sample image
