IPsec Usenix. IPSec with IKEv2 should in theory be the faster than OpenVPN due to user-mode encryption in OpenVPN however it depends on many variables specific to the connection In most cases it is faster than OpenVPN When used in its default UDP mode on a reliable network OpenVPN performs similarly to IKEv2.
Unlike IPv4 IPsec security is mandated in the IPv6 protocol specification allowing. ESP-protected packets as well 26 ESP is IP protocol number 50 The ESP version 2 standard is defined in RFC 2406 IP Encapsulating Security. It provides protection for the entire IP packet and is sent by adding an outer IP header corresponding to the two tunnel endpoints.
IPsec IKE. IPSec Transport mode is used for end-to-end communications for example for communication between a client and a server or between a workstation and a gateway if the gateway is being treated as a host A good example would be an encrypted Telnet or Remote Desktop session from a workstation to a server.
