What is L2TP?

Layer Two Tunneling Protocol (L2TP) is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by ISPs. It does not provide any encryption or confidentiality by itself. It relies on other encryption protocols like IPSec to provide security. L2TP is commonly used to enable secure connections between remote users and private networks.
