I have IRC server which shall provide full access with no restrictions for users within a network (say 8 class C IP addresses) and when user connects from outside he must /msg NickServ identify <password> (in ~2 minutes) or he will be disconnected, if he tries to join a channel or write privMSG anywhere else than to NickServ, or use notice or even try to register he will be disconnected immediately.
Is there any "nice way" how to do that?
