shai_guwapo perhaps your connection devices don't utilise UPnP technology. If they don't you may need to forward a port on your modem/router. See: http://portforward.com/routers.htm

If you do need to do this the steps are: 1. Set up a Static IP (most important.) 2. Forward a port such as port 6346. 3. Within LW Manual port forward instructions & sample image & 2 posts after that.

If this is not the issue then it 'might' be an ISP provider problem. They might be filtering p2p use.
