www.tinc-vpn.org Tinc is an open-source , self-routing, mesh networking protocol and software implementation used for compressed and encrypted virtual private networks . It was started in 1998 by Guus Sliepen, Ivo Timmermans, and Wessel Dankers, and released as a GPL -licensed project.
In computer networking, Secure Socket Tunneling Protocol (SSTP) is a form of virtual private network (VPN) tunnel that provides a mechanism to transport Point-to-Point Protocol (PPP) traffic through an SSL/TLS channel.
Optional. Padding for encryption, to extend the payload data to a size that fits the encryption's cipher block size, and to align the next field. Pad Length: 8 bits Size of the padding (in octets). Next Header: 8 bits Indicates the protocol type of the Payload Data, [27]: §2.6 like the value 6 for TCP.
Virtual private network (VPN) is a network architecture for virtually extending a private network (i.e. any computer network which is not the public Internet) across one or multiple other networks which are either untrusted (as they are not controlled by the entity aiming to implement the VPN) or need to be isolated (thus making the lower network invisible or not directly usable).

A HAIPE is an IP encryption device, looking up the destination IP address of a packet in its internal Security Association Database (SAD) and picking the encrypted tunnel based on the appropriate entry. For new communications, HAIPEs use the internal Security Policy Database (SPD) to set up new tunnels with the appropriate algorithms and settings.
In data messages, Nr is reserved and, if present (as indicated by the S bit), MUST be ignored upon receipt.. Offset Size (optional) Specifies where payload data is located past the L2TP header. If the offset field is present, the L2TP header ends after the last byte of the offset padding. This field exists if the offset flag is set.
Commercial VPN services are often used by those wishing to disguise or obfuscate their physical location or IP address, typically as a means to evade Internet censorship or geo-blocking. Providers often market VPN services as privacy-enhancing, citing security features, such as encryption, from the underlying VPN technology.
