I have a vague memory that Win95 (and therefore probably Win98) allowed a single dial-IN to itself, and contained ppp server functionality for that one connection. Perhaps w2k-pro has removed it. It is normal for a ppp client to send the ipcp conf-req asking for 0.0.0.0, expecting to get a conf-nak with the ip address assigned by the server. The client then sends another conf-req with the server-assigned ip address, which the server acks. Why is the fbsd box acting as a client, rather than a server? Who initiated the "connection"? One side or the other is going to have to assign ip addresses to each side of the connection. Have you tried connecting two w2kpro boxes this way? Does it work?
