Support for IPv6 addresses is relatively new in OpenVPN. As IPv6 addresses are now being used more and more by companies and Internet Service Providers, this recipe provides a setup for using IPv6 for tunnel endpoints as well as using it inside the tunnel.
This recipe is a continuation of the previous one. Install OpenVPN 2.3.9 or higher on two computers. Make sure the computers are connected over a network. Set up the client and server certificates using the previous recipe. For this recipe, the server computer was running CentOS 6 Linux and OpenVPN 2.3.9 and the client was running Fedora 20 Linux and OpenVPN 2.3.9. Keep the configuration file, basic-udp-server.conf
, from the previous recipe at hand as well as the client configuration file, basic-udp-client.conf
.
