You could try changing ports to one like 64049. In LW tools > options > advanced > firewall config is where to change LW's listening port. Apply to save a change. Any ports allowed thru a software firewall or forwarded thru a router should be the same number as the listening port.
Have you always seen the firewall icon, or is this a new thing?
