VPN introduction Zine

This zine is all about how virtual private networks function, why and when to use them, what free and open source software is available. Technical language is simple, yet still valuable to users with various backgrounds of computer knowledge. It gives examples of how the IPsec protocol and openVPN software can establish secure network connections.
