Fen and I have been trying for two days to figure out how to play the regular NWN campaign together online. We tried using nwserver and "start a new multiplayer game" both to no avail. We can set up a server at Chapter 1 with nwserver and the one hosting can direct connect to it but the other can't. No matter what we do, our server won't show up in the list. Help?

I think this has to do with firewall settings, I remember a similar problem a long time ago. Either both or one of you is blocking the other from seeing the other due to firewall type protections. Hope this helps
