VPN protocols: L2TP/IPsec. Learn more about the benefits of using L2TP/IPsec. 30-day money-back guarantee. What is L2TP/IPsec? L2TP stands for Layer 2 Tunneling Protocol. L2TP was first proposed in 1999 as an upgrade to both L2F Layer 2 Forwarding Protocol and PPTP Point-to-Point Tunneling Protocol. Because L2TP does not provide strong encryption or authentication by itself, another protocol called IPsec is most often used in conjunction with L2TP. IPsec stands for Internet Protocol security.

This field exists if the offset flag is set. Offset Pad optional. Variable length, as specified by the offset size. Contents of this field are undefined. Variable length Max payload size Max size of UDP packet size of L2TP header L2TP packet exchange edit. At the time of setup of L2TP connection, many control packets are exchanged between server and client to establish tunnel and session for each direction. One peer requests the other peer to assign a specific tunnel and session id through these control packets. Then using this tunnel and session id, data packets are exchanged with the compressed PPP frames as payload. The list of L2TP Control messages exchanged between LAC and LNS, for handshaking before establishing a tunnel and session in voluntary tunneling method are. Because of the lack of confidentiality inherent in the L2TP protocol, it is often implemented along with IPsec. This is referred to as L2TP/IPsec, and is standardized in IETF RFC 3193. The process of setting up an L2TP/IPsec VPN is as follows.:
What is Layer 2 Tunneling Protocol L2TP? Definition from Techopedia.
Layer 2 Tunneling Protocol L2TP is a computer networking protocol used by Internet service providers ISPs to enable virtual private network VPN operations. L2TP is similar to the Data Link Layer Protocol in the OSI reference model, but it is actually a session layer protocol.
What Is L2TP Layer 2 Tunneling Protocol? CactusVPN.
Like the name implies, an L2TP VPN is a VPN service that offers users access to the L2TP protocol. Please be aware that you arent very likely to find a VPN provider who only offers access to L2TP on its own.
RFC 2661 Layer Two Tunneling Protocol L2TP."
As such, L2TP is only concerned with confidentiality, authenticity, and integrity of the L2TP packets between its tunnel endpoints the LAC and LNS, not unlike link-layer encryption being concerned only about protecting the confidentiality of traffic between its physical endpoints.
