L2TP/IPsec is a good VPN solution for non-critical use. This is especially true on legacy devices that do not support OpenVPN. It has, however, been severely compromised by the NSA. SSTP offers most of the advantages of OpenVPN, but is primarily only a Windows protocol. This does mean that it is better integrated into the OS, but it is poorly supported by VPN providers thanks to this L2TP/IPSec is a step up from PPTP, but it’s also one of the slowest connections, and its security is questionable. SSTP is pretty good for Windows users. It’s fast and easy to setup, but once again you don’t know how secure and private your connection is. IKEv2/IPSec is a pretty good choice for mobile users and a must-have for Blackberry users. But, beyond that go with OpenVPN. SoftEther L2TP/IPsec est un protocole intégré à la plupart des ordinateurs, téléphones et tablettes. C'est un bon choix si OpenVPN n'est pas pris en charge par votre appareil, et si la sécurité est votre priorité principale. OpenVPN ™ Seulement Diamond. OpenVPN est le protocole recommandé pour les ordinateurs de bureau équipés avec Windows, Mac OS X et Linux. La meilleure performance 28/06/2018

28/06/2018 · L2TP connects the networks of RUT1 and RUT2 and IPsec provides the encryption for the L2TP tunnel. When the scheme is realized, L2TP packets between the endpoints are encapsulated by IPsec. Since the L2TP packet itself is wrapped and hidden within the IPsec packet, the original source and destination IP address is encrypted within the packet.

L2TP et IPsec doivent tous deux être pris en charge par le client VPN et le serveur VPN. L2TP est installé avec le protocole TCP/IP. Encapsulation. L’encapsulation des paquets L2TP/IPsec est constituée de deux couches : Première couche : encapsulation L2TP. Une trame PPP (un datagramme IP) est enveloppée dans un en-tête L2TP et un en-tête UDP. Structure d’un paquet L2TP contenant un

IKEv2/IPSec presents a new challenger to OpenVPN, improving on L2TP and other IPSec-based protocols with faster connections, more stability, and built-in support on most newer consumer devices. SSL and IPSec both boast strong security pedigrees with comparable throughput speed, security, and ease of use for most customers of commercial VPN services.

Ce n'est pas le protocole le plus rapide. Le L2TP / IPSec encapsule les données deux fois, ce qui ralentit la connexion. Nécessite une bande passante et un temps de traitement importants. 04/04/2018 · L2TP/IPsec. Layer 2 Tunnel Protocol is a VPN protocol that doesn’t offer any encryption. That’s why it’s usually implemented along with IPsec encryption. As it’s built into modern desktop operating systems and mobile devices, it’s fairly easy to implement. But it uses UDP port 500 — that means it can’t be disguised on another port, like OpenVPN can. It’s thus much easier to block and harder to get around firewalls with.
