Something's blocking LW's default port. A few people have had trouble trying to connect if they're on satellite.
Did you try changing to a higher port? You could try calling your ISP & asking if they're blocking p2p. I don't know if the article below's going to help at all (don't know if your with Optus... Google found it when I was looking for info about your modem), have a read anyway.
