[http://openvpn.net OpenVPN] is a full-featured open source SSL VPN solution that accommodates a wide range of configurations, including remote access, site-to-site VPNs, Wi-Fi security, and enterprise-scale remote access solutions with load balancing, failover, and fine-grained access-controls. Starting with the fundamental premise that complexity is the enemy of security, OpenVPN offers a cost-effective, lightweight alternative to other VPN technologies that is well-targeted for the SME and enterprise markets.

This contrib will help you configuring OpenVPN in bridge mode. With this mode, clients connecting to the VPN from the outside will get an IP in the local subnet, the VPN and the Internal Interface are bridged. There's no routing problem, no additional firewall rules. The downside is that you cannot limit which services VPN clients has access to, they are just treated as locally connected computers.

The configuration is the new way to apply specific configuration to a client. As now the certificates are managed separatly, you have to create rules separatly. It's still quite simple, just add a new rule, enter the common name to match, a comment, choose an optional fixed IP, choose to enable/disable the gateway redirection, or even block a specific client. Then save, and you're done.
