OpenVPN is an open source software application that implements virtual private network (VPN) techniques for creating secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. It uses a custom security protocol that utilizes SSL/TLS for key exchange. It is capable of traversing network address translators (NATs) and firewalls. It was written by James Yonan and is published under the GNU General Public License (GPL).
OpenVPN allows peers to authenticate each other using a pre-shared secret key, certificates or username/password. When used in a multiclient-server configuration, it allows the server to release an authentication certificate for every client, using signature and Certificate authority. It uses the OpenSSL encryption library extensively, as well as the SSLv3/TLSv1 protocol, and contains many security and control features. (Source: Wikipedia)
What are the advantages and disadvantages of Open VPN protocol?
OpenVPN provides the best speed and security during your VPN connection, and it also passes the majority of firewalls and network/ISP restrictions.
OpenVPN is not as easy to setup compared to other VPN protocols, and a VPN installation with OpenVPN can be difficult for some clients, as it requires the installation of a special client application. OpenVPN is also not supported by some mobile devices, which can be a strong disadvantage for VPN mobile use.
