Useful tips for setting up a virtual private network

The websites you visit often track where you came from and watch where you head off to next.

A VPN - or virtual private network - helps you browse the internet more anonymously by routing your traffic through a server that is not your point of origin.

Many companies offer VPN services - with varying levels of security and cost - but if you are willing to take the time you can create your own VPN with some basic coding and a Raspberry Pi computer.

You can then connect external devices like a smartphone to this VPN tunnel to browse the internet more securely through your home network, and access shared files and media on your home computer.
