L2TP on the other hand provides enhanced security with 256 bit encryption but has a significant impact on Internet speed. Ce protocole utilise un canal de contrôle sur TCP et un tunnel GRE pour encapsuler des paquets PPP. La spécification PPTP ne décrit pas le cryptage ou les fonctions d’authentification et s’appuie sur le tunnel du protocole Point-to-Point pour implémenter des fonctionnalités de sécurité.
