Layer 2 Tunneling Protocol (L2TP): A protocol used to support virtual private networks (VPNs), which provides a private, secure path for data transmission across a public network such as the internet. L2TP creates a tunnel between two L2TP connection points and encapsulates data sent between them. While L2TP itself doesn’t provide encryption, it’s often used in conjunction with the IPsec protocol, which does provide encryption, to create a more secure VPN.
