Not a good idea to post your ip address in the forums, it's also against the rules. That said, I tried to connect to you but was unable to, though the port number LW uses is also needed(I tried :6346).
You need to allow LW access through your firewall and router/modem.
If you give some more details of your set-up, it'll make it easier to help. See:
