Layer 2 Tunneling Protocol - Wikipedia
网页IPsec is often used to secure L2TP packets by providing confidentiality, authentication and integrity. The combination of these two protocols is generally known as L2TP/IPsec (discussed below). The two endpoints of an L2TP tunnel are called the L2TP access concentrator (LAC) and the L2TP network server (LNS). The LNS waits for new tunnels.

Layer 2 Tunneling Protocol L2TP/IPsec - ExpressVPN
网页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 …

What Is L2TP (Layer 2 Tunnel Protocol)? - Palo Alto Networks
网页L2TP is a tunneling protocol, often used to support VPNs, which encapsulates data for secure transmission over public networks. L2TP is often paired with IPsec because it does not encrypt data by itself. The combination of L2TP and IPsec ensures confidentiality, integrity, and authentication of the data packets transmitted through the VPN tunnel.
Configuring Layer 2 Tunneling Protocol (L2TP) over IPSec
网页2006年1月19日 · Use this sample configuration to encrypt L2TP traffic using IPSec for users who dial in. L2TP tunnel is established between the L2TP Access Concentrator (LAC) and the L2TP Network Server (LNS). An IPSec tunnel is also established between these devices and all L2TP tunnel traffic is encrypted using IPSec.
