IPsec is a whole family of connection protocols. Most of the time, IPSec is used with the key exchange protocols ikev1 (aka Cisco IPSec) or ikev2. L2TP/IPSec is less common nowadays. Like PPTP, IPSec is available “out of the box” in most modern operating systems. IPSec tries to fix the known weaknesses of PPTP, which works well in most cases.

Jun 30, 2020 · VPN Protocols. PPTP is very insecure and should be avoided. While its ease of setup and cross-platform compatibility are attractive, L2TP/IPsec has the same advantages and is much more secure. L2TP/IPsec is a good VPN solution for non-critical use. This is especially true on legacy devices that do not support OpenVPN. There are five major/widely used protocols for VPNs, OpenVPN, PPTP, L2TP/IPsec, SSTP, and IKEv2/IPSec which each have their own pros and cons. In this article we’ll discuss the five major VPN protocols, explaining how each protocol works, what activities it is best configured for, and what the pros and cons are. Aug 13, 2019 · This VPN protocols guide is meant to serve as a basic overview of the main VPN protocols in use today: OpenVPN, L2TP/IPSec, IKEv2/IPSec, WireGuard, PPTP, and SSTP. For more in-depth information on each protocol, you can examine references from the respective developers. IPsec is a whole family of connection protocols.

Like PPTP, IPSec is available “out of the box” in most modern operating systems. IPSec tries to fix the known weaknesses of PPTP, which works well in most cases. In comparison with other VPN protocols, L2TP/IPSec is more “whimsical” when it comes to stable and safe work. So, if the VPN Client is based on the network device transforming network addresses or not supporting packages via the 500 UDP port, the L2TP/IPSec connection will not be established.

L2TP/IPSec- Layer 2 Tunneling Protocol. L2TP is an improved version of PPTP and is strictly a tunneling protocol. When used with IPSec, it creates a strong VPN tunnel with secured packets. The encryption standard of L2TP/IPSec is the same as the underlying IPsec at 256-bit AES making the implementation of this VPN protocol fairly secure.
