So what you really need is a 2-part scenario. One VM with 2 network connections... one facing the outside world using either NAT or bridged; and the other on a private guest-only network (use any of the unused VMnet switches 2-7, 9). Also needing routing software inside it to do the NAT routing for it's guests. Then, the client VM connects to the guest-only network to receive it's IP address from the server, and also routing to the outside world.
