The Layer Two Tunnel Protocol (L2TP) is a tunnel protocol that is used to support virtual private networks (VPNs) or as part of the provision of services by Internet service providers. It does not provide any encryption or confidentiality in itself.

The Layer Two Tunnel Protocol (L2TP) protocol is designed on all modern operating systems and devices that support VPN. ... alone, L2TP does not provide any encryption or confidentiality for the traffic it is going through, so it is generally applied using an IPsec Authentication Kit (L2TP / IPsec).

L2TP generally uses the authentication protocol, IPSec (Internet Protocol Security). Use strong encryption and documentation. IPSec gives you a final advantage over some of the most commonly used protocols such as PPTP. The protocol uses UDP ports 1701. L2TP is the VPN protocol that does not provide encryption or protection against traffic passing through the connection. For this reason, it is usually combined with IPSec, which is an encryption protocol.

Layer Two Tunneling Protocol (L2TP) is a computer network protocol that the ISP uses to enable virtual private network (VPN) operations. L2TP is similar to the data link layer protocol in the OSI reference model, but in reality it is a session layer protocol.
