PPTP is a tunneling protocol just like L2TP is - it does not provide security. PPTP uses MPPE for encryption which may have some disadvantages compared to IPSEC (which is commonly used with L2TP). IPSEC can also be used on its own as a tunneling protocol and this is pretty common.
The combination is written as L2TP/IPsec and is spoken as, “L2TP over IPsec.” When used together, L2TP encapsulates the packets to be transferred. IPsec provides encryption and a second layer of encapsulation, making the combination secure. While this might seem like a clumsy way to do things, L2TP/IPsec is still pretty popular. One reason is that it is built right into many operating systems, including Windows, macOS, Linux, iOS, and Android. In fact, in many enterprises, it isn't an SSL/TLS VPN vs. IPsec VPN; it's an SSL/TLS VPN and IPsec VPN. Both IPsec and SSL/TLS VPNs can provide enterprise-level secure remote access, but they do Jan 19, 2006 · L2TP tunnel is established between the L2TP Access Concentrator (LAC) and the L2TP Network Server (LNS). An IPSec tunnel is also established between these devices and all L2TP tunnel traffic is encrypted using IPSec. Prerequisites Requirements. This document requires a basic understanding of IPSec protocol. To learn more about IPSec, please
Since L2TP doesn’t have any encryption or authentication capabilities (both are key features of VPNs) on its own, IPSec VPN is often paired with it. The framework is also used to provide security for other protocols such as IKEv2. Apr 15, 2019 · IPsec is a time-tested system, while SSL is growing increasingly common. Each protocol has its strengths and weaknesses. MSPs will need to decide which solution is right for each client’s individual needs. SolarWinds MSP is here to help.

L2TP/IPsec is a protocol built into most desktop, phone, and tablet devices. It is a good choice if OpenVPN isn't supported by your device and security is top priority. OpenVPN ™ Diamond Only OpenVPN is the recommended protocol for desktops including Windows, Mac OS X and Linux.
L2TP. Layer 2 Tunneling Protocol or L2TP is a tunneling protocol that allows remote users to access the common network. L2TP lets a Point-to-Point Protocol (PPP) session travel over several networks and links. L2TP was actually taken from PPTP of Microsoft and Cisco’s L2F or Layer 2 Forwarding technology. The Layer 2 Tunneling Protocol (L2TP) is a standard protocol for tunneling L2 traffic over an IP network. Its ability to carry almost any L2 data format over IP or other L3 networks makes it Mar 15, 2016 · L2TP/IPsec. L2TP/IPsec is the combination of two protocols to create a VPN tunnel. L2TP (or ‘Layer 2 Tunneling Protocol’) is a tunneling protocol that allows the transport of data packets between two end points. L2TP does not include any encryption capabilities on its own, so it is often combined with an encryption protocol.
