"VPN connections let you remotely access file or connect remote offices together via secure tunnels over the Internet. They can even come in handy to secure connections on public Internet ports or Wi-Fi hotspots, hiding Internet traffic from local eavesdroppers.
"If you aren't going to have more than two-dozen VPN users, you might consider setting up your own VPN server using the DD-WRT router firmware. If you have a compatible wireless router, you can load the firmware on it. This gives you an OpenVPN server and client, and many more cool features. You can then set it up for remote access connections or site-to-site connections to connect offices together.
"DD-WRT supports two different VPN protocols: Point-to-Point Tunneling Protocol (PPTP), which is very popular but has vulnerabilities, and OpenVPN, which uses Secure Sockets Layer (SSL) and Transport Layer Security (TLS) for a much more secure solution. In this two-part tutorial, we will set up and use OpenVPN."
