If you want to get started with VPNs and Linux without a lot of hassle, here are some recommendations:
Get A Pre-Configured VPN Router
A pre-configured VPN router can provide all your computers and mobile devices with encrypted internet connections. You won’t have to install a VPN client on each device, and all your devices count as one connection with your VPN provider.
The easiest way to install a VPN router is to buy one that is pre-flashed and pre-configured for a specific VPN service. See my article “The Best VPN Routers Of 2014” for more information.
A Desktop With Linux Pre-Installed
ThinkPenguin sells desktop and laptop computers that come with Linux pre-installed and pre-configured. It’s the easiest way to get up-and-running with Linux.
