WireGuard Communication Protocol

The WireGuard communication protocol is available in UEK R7 for both IPv4 and IPv6 networks. WireGuard uses encrypted virtual private networks (VPNs) by passing traffic over the User Datagram Protocol (UDP).

Note:

WireGuard was previously enabled as a technology preview feature in UEK R6U1, with full support introduced in UEK R6U3.

WireGuard uses public key encryption for identification and encryption, while OpenVPN uses certificates for these tasks. With WireGuard, secure key generation and management is handled in the background. Note that although IPsec is still the standard for secure network communication, WireGuard is gaining in popularity because it is simpler to configure, as well as deploy.
