OpenPVN is an easy to set-up and use VPN solution that offer TUN/TAP support. In this tutorial I describe how to set-up an OpenVPN connection between a Ubuntu server and an Arch client. Preparations (Server) First we have to install OpenVPN on the server. # apt-get install openvpn To see whether TUN/TAP is enabled in the kernel we can check the kernel log grep tun /var/log/kern.log and load it if it doesn’t show up modprobe tun.
