A few weeks ago we covered installing Tomato, an open-source router firmware, on your Linksys WRT54GL. Today we’ll be going over how to install OpenVPN alongside Tomato, and setting it up to access your home network from anywhere in the world! What is OpenVPN? A virtual private network (VPN) is a trusted, secure connection between one local area network (LAN) and another. Think of your router as the middle man between the networks that you’re connecting to. Both your computer and the OpenVPN server (your router in this case) “shake hands” using certificates that validate each other. Upon validation, both the client and server agree to trust each other and the client is then allowed access on the server’s network.
Typically, VPN software and hardware cost a lot of money to implement. For more information about OpenVPN, visit the official What Is OpenVPN?

VPN-ing into your server will allow you to connect to every possible service running on it, as if you were sitting next to it on the same network, without individually forwarding every port combination for every service you would like to access remotely.
Using a VPN connection also has the upshot of, if desired, granting access to other computers on the network as if you where in it locally from anywhere across the internet. While not the most secure of the VPN solutions out there, PPTP is by far the simplest to install, configure and connect to from any modern system and from windows specifically as the client is a part of the OS since the XP days and you don’t need to mess with certificates (like with L2TP+IPsec or SSL VPNs) on both sides of the connection. Did i get you interested? Then let’s go :) Preface Server Setup Install the pptp server package: sudo aptitude install pptpd Edit the “/etc/pptpd.conf” configuration file: sudo vim /etc/pptpd.conf Add to it: sudo vim /etc/ppp/pptpd-options.
