Emulating a Redirecting Load Balancer for WI and PNA

I recently had to reproduce an error concerning a load balanced Program Neighborhood Agent (PNA) installation.

So I ended up asking myself whether it is possible to build a virtualised environment with a minimum of resources, preferably in a single virtual machine. At the same time, the underlying concepts still need to apply for the error to be reproducible.
