Eventually, the data is bundled twice: first by L2TP, then by IPsec. It then creates the Encapsulated Security Payload, which lets the devices on either end know that the data really comes from where it claims to come from. IPsec carries out the security association, where your device and the VPN server agree on what security and encryption tools to use. However, L2TP borrows only the security features. By itself, IPsec appeared in 1995, and it can carry out the steps needed to create a VPN tunnel. That’s why L2TP is used together with IPsec. Naturally, tunneling wouldn’t be worth much if the data wasn’t encrypted. However, due to an IPsec/L2TP limitation, if you wish to connect multiple devices from behind the same NAT (e.g. The same VPN account can be used by your multiple devices. There are 39 free l2tp vpn servers ready to use. Windows users: For IPsec/L2TP mode, a one-time registry change is required if the VPN server or client is behind NAT (e.g. With encryption features that are higher than PPTP VPN and are widely used on routers, miktorik or smart tv devices, but still easy to use and compatible for all devices.
L2TP VPN CLIENT MAC OS X
It remains in use due to being implemented on Windows platforms since Windows 2000, on Mac since Mac OS X 10.3, as well as having a wide variety of Linux versions. L2TP VPN (two-point layer tunneling protocol). First, why is it not implemented in the network. This allows running protocols over networks that can’t support them (as the data of the former is packed in a way that’s friendly to the latter) – or transmitting private data securely. Im tring to set up L2TP/IPsec VPN connection on Fedora 34 (it could be 33 as well), but fail to succeed. Tunneling bundles up data for transmission over a network – think of putting an envelope into another envelope. L2TP builds upon two older tunneling protocols: Layer 2 Forwarding Protocol by Cisco and (ancient and unsecure) PPTP by Microsoft.

As a standard, Layer 2 Tunneling Protocol – protocol being a set of procedures that directs digital communication processes – was first proposed in 2000.
