I’ve been playing with OpenVPN for the past couple of weeks and I’m pretty impressed. OpenVPN allows you to create a private network between 2 computers. These could be 2 servers or a client and a server. A few of the reasons for wanting to do this are –
- bypassing your ISPs traffic shaping
- making your traffic appear to originate from a different country
- encrypting your laptop traffic over an insecure link – such as a coffee shop wifi connection
- anonymous web surfing
- bypassing a countries web access controls
Setup and configuration of the server component can be fairly complicated depending how you want to manage the certificates and networking on there. It’s possible to install it on Linux or Windows although I’ve only tested it on Linux. Running the server on Linux you also need to configure iptables to translate your private ‘vpn’ ip address to an external ip address on the vpn server.
