You could run a virtual machine on your real machine and a bridge-mode network connection between the two. Then run the server on one and the client on the other.

However, you will not get a good picture of how well it responds under heavily loaded network conditions. For that you truly need a private network with a phantom load generator.

VirtualBox, VirtualPC, and vmware can do this. You might get better/more responses on superuser.com.
