L2TP

In this article we will discuss L2TP, will make brief discussion on L2TP, last article we discuss about NetBIOS.

Layer 2 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.

L2TP/IPSec provides a highly secure and reliable connection. L2TP is advanced protocol when compared to PPTP and is combined with IPSec in order to obtain better security. The speed may be lower than PPTP but Internet speed varies based on a number of factors. Usually, the difference in speed is negligible.

Layer 2 Tunneling Protocol (L2TP) is built in to almost all modern operating systems and VPN-capable devices. On its own, L2TP does not provide any encryption or confidentiality to traffic that passes through it, so it is usually implemented with the IPsec authentication suite (L2TP/IPsec).

L2TP (Layer Two Tunneling Protocol) defines an extension to PPTP (Point-to-Point Tunneling Protocol) that an ISP (Internet Service Provider) uses to allow a VPN (Virtual Private Network) to operate. L2TP combines L2F from Cisco Systems’ optimum features and PPTP from Microsoft into a single protocol.
