In order to do this I will setup my own Certificate Authority using the provided easy-rsa scripts in the /usr/share/doc/openvpn/examples/easy-rsa/ directory. (I really only understand the bridge_ports directive and the bridge_stp directive. The bridging declarations come from the libvirt documentation. If you are running Linux inside a virtual machine, you may want to add the following parameters to the bridge connection:Д«ridge_fd 9 # from the libvirt docs (forward delay time)Д«ridge_hello 2 # from the libvirt docs (hello time)Д«ridge_maxage 12 # from the libvirt docs (maximum message age)Д«ridge_stp off # from the libvirt docs (spanning tree protocol).So that it look similar to: # This is the network bridge declaration For more information, see interfaces(5).Д®dit this and add a bridge interface: sudo nano /etc/network/interfaces # This file describes the network interfaces available on your system When a Linux server is behind a NAT firewall, the /etc/network/interfaces file commonly looks like

Sudo apt-get install openvpn bridge-utils Comments in configuration files are preceeded by two pound signs (#). In my configuration eth0 is connected to the Internet and eth1 is connected to the LAN network that will be bridged. This example installation was performed using Ubuntu Jeos 8.04 in a KVM virtual machine (but could just have easily been performed on a standalone Ubuntu Server). These instructions are for setting up a Bridged VPN on Ubuntu 8.04 using x509 certs and some general administration tasks.

Note that good networking knowledge and enough time is required to follow this manual setup guide. Therefore, all LAN services are visible to the remote clients.

When you bridge a physical Ethernet device and a tap device, you are essentially creating a hub between the physical network and the remote clients. A tap device acts as a virtual Ethernet adapter and the bridge device acts as a virtual hub. The VPN accomplishes this by using a combination of virtual devices - one called a 'bridge' and the other called a 'tap device'.

There is also a commercial Web GUI which might be easier to set up and maintain, especially for non-experts, and which allows clients to download VPN configurations themselves using the web browser.ДЄ bridged VPN allows the clients to appear as though they are on the same local area network (LAN) as the server system. Setup examples are also provided on the OpenVPN community website. This page refers to the community version of the OpenVPN server. It belongs to the family of SSL/TLS VPN stacks (different from IPSec VPNs).

OpenVPN is a Virtual Private Networking (VPN) solution provided in the Ubuntu Repositories.
