Jeffery Douglas Waddell, from the Linux Documentation Project provides us with a comprehensive look at securing your booting stage with VPN capabilities. As he states in the beginning:

For several years now, users at the Institution where I currently work part-time have expressed a need for a robust and secure connection to the internal network. The internal network actually has some clients that are on private networks and some clients that are Internet-routeable. Read on for the connecting quickly and securely.

1. Introduction

For several years now, users at the Institution where I currently work part-time have expressed a need for a robust and secure connection to the internal network. The internal network actually has some clients that are on private networks and some clients that are Internet-routeable.

Being mostly a Microsoft shop, the options that have been available were not deemed appropriate for various reasons, usually due to security concerns. After being introduced to the problem a few months ago and listening to the concerns surrounding it, I suggested using a boot CD, which would alleviate all of their security concerns. They gave me the go ahead to give it a try. I now have a working prototype and this document describes the process used to create it.
