is easy to build cross-platform, point-to-point VPNs using x509 PKI (Public Key Infrastructure) or custom configuration
files.
OpenVPN allows secure tunneling of data through a single TCP/UDP port over an unsecured network, thus providing
secure access to multiple sites and secure remote administration to a console server over the Internet.
OpenVPN also allows the use of Dynamic IP addresses by both the server and client thus providing client mobility. For
example, an OpenVPN tunnel may be established between a roaming windows client and an Opengear advanced
console server within a data center.
Configuration of OpenVPN can be complex so Opengear provides a simple GUI interface for basic set up as described
below. However for more detailed information on configuring OpenVPN Access server or client refer to the HOW TO and
FAQs at

TAP are part of the Linux kernel.
