It's good you've got your Win firewall off, you shouldn't run 2 firewalls together.

Do the port test in the thread. Pay attention to the parts about UPnP. If your router uses UPnP then it has to be enabled both within the router & within LW (tools > ooptions > advanced > firewall config. Tick 'use UPnP' then apply).
