I do understand but you didn't get what I was saying... PPP on the client machine will ask the server which is SLiRP for the ip address so SLiRP for each user needs to have some kind of config file so that it won't be using the wrong ip address that someone else is supposed to use... > OS/2 Warp, Winsock, etc installed on user's machine.

I know what you mean but even with my current ppp connection on my FreeBSD boxm it asks the remote for my ip address so SLiRP will need to have a config file for each user so it doesn't use the wrong address...
