For my lab, I am working on a single workstation using Virtualbox. The lab experiment needs Internet access, but I want to use DHCP, and I don’t want to cause issues with the rest of the network which would make life difficult for the rest of the family. This requires two things:

1. A dedicated host-only network, provided by Virtualbox, to keep DHCP limited to these machines.

2. A routing device to connect the virtual machines to the Internet.

The final network will look like this:

Future posts will detail the rest of the lab setup, including the routing process and setup of the orchestration master VM.

Historically, I have worked for companies that offer IT services for small companies, from the 3-person single-room rented office to 250-employee manufacturing firms.

Recently, my work has led me to be in a systems administrator role managing hundreds of servers. This has enlightened me to a whole new realm of possibility and challenge.

One of the first challenges I am seeing is the need to become far more skilled at scaling my knowledge and experience managing systems.

To that end, I am working on some items in my home lab which will hopefully give a better experience for myself and those that I serve.

Over the next few posts, I plan to discuss in greater detail the types of challenges I am facing as well as the experiments I am doing to solve those challenges.
