OpenVPN is a very powerful and flexible VPN daemon. OpenVPN supports SSL/TLS security, Ethernet connectivity, TCP or UDP tunneling via proxy or NAT, support for dynamic IP and DHCP addresses, scalability for hundreds or thousands of users, portability across most major operating systems slowly
OpenVPN is closely related to the OpenSSL library and derives many of its own encryption capabilities.
OpenVPN uses regular encryption using a pre-shared secret key (static mode key) or public key security (SSL/TLS mode) using client and server certificates. OpenVPN also supports unencrypted TCP/UDP tunnels.
OpenVPN is designed to work with the TUN / TAP virtual network interface found on most operating systems. Overall, OpenVPN intends to offer many key IPSec features but a relatively light footprint.
With OpenVPN you can: -Balanced VPN Server Farm -Using one or more devices that can handle thousands of dynamic connections from incoming VPN clients With all the features of encryption, authentication and authentication Use the OpenSSL library to protect your network traffic When submitting online. , use any HMAC cipher, key size, or digest (for datagram integrity check) supported by the OpenSSL library, between normal key-based encryption or certificate-based public key cryptography, using static, pre-shared keys, or certified dynamic TLS key exchange, and the use of real-time adaptive link compression and traffic shaping to manage link bandwidth usage, tunnel networks in which public endpoints are dynamic, such as DHCP or dial-up clients, and tunnel networks. Firewalls without the need for explicit firewalls, tunneling over NAT, creating secure Ethernet bridges with virtual Ethernet devices, and OpenVPN control using a graphical user interface in Windows or Mac OS X

Updates:OpenVPN Library 3 Updated to version 3.6.2. Added Gateway Recognition Feature: OpenVPN Connect notifies the user when the device is connected to the network and the captive gateway is active. This function is enabled by default and can be managed in the application settings page. Added Network Loss Detection: The VPN connection goes into "paused" mode when disconnected, and automatically resumes the VPN session when the network is established. Adding a command line interface to the OpenVPN Connect function, see Command Line Function. Changes in software update performance: Added the ability to change the frequency setting for software update checks. Checks if update frequency management is added by the administrator using instructions to profile: 0 never; 1 Every day Once every 7 weeks 30 months after you add a profile to the app with these instructions, the app's settings change automatically. CONNECTV3_PREFERENCE_UPDATE_FREQUENCY = <0 | 1 | 7 | 30> When a new version of the program is available, it will be visible in the main menu of the program. Release notes have been added to the app update notification. Additional support for PKCS11 hardware icons. See Support for physical tokens #PKCS11 for OpenVPN Connect support. Replace restart options with restart options. The user can choose from several options: run the program after restarting the operating system, connect to the last connected profile, or connect only if the connection was active on restart (previously the "restart on startup again" behavior"). Adding external certificates in Windows 7: OpenVPN Connect supports entering and assigning an external PKCS12 identity to a connection profile in Windows 7. Added advanced settings section Settings that can be disconnected are hidden in the advanced settings section of the settings page Colored tray icons added Can be activated OpenVPN Connect tray icon by displaying connection status color on Settings page (default behavior in Windows 7 and Windows 8) Old compatibility option "AES-CBC password" removed Various bug fixes and user experience improvements
