Hello, sorry on the late reply.
My router does have UPnP, i have it checked off. My XP computer is using UPnP, i have not changed any settings on it. My Vista computer is Portforwarded but still can't connect. LW's listening port and port forward box in router is set to the same number. <10227>. i also did delete LW's preferences folder already. I also seen ur reply on one of my replies a while ago, i really don't think alot of people use the same model of router that i am using at the moment. i also had some problems with my router before. I'm pretty sure i have the cheaper, less popular Dlink router. My english grammar might not be the best, i am learning in French.
