Virtual Wall tutorial: server and client with network latency

In this tutorial, we will show you how to set up a client and server node, with layer 2 network in between with a certain latency. The server will run an iPerf server instance, after which we will run an iPerf client instance on the second node. By using the correct IP addresses, we make sure that the iPerf traffic stream is routed over the dedicated layer 2 network.
