The L2TP over IPSec implementation available in macOS supports multiple authentication mechanisms.Īs the L2TP/IPSec consists of two parts, each of them has its own authentication: MacOS provides native support for the L2TP/IPSec protocol (called L2TP over IPSec), and you may set it up manually from the Network settings. IPSec with AES encryption is considered secure, despite rumors that the NSA deliberately weakened the protocol. L2TP/IPSec uses a process called double encapsulation: firstly it establishes a PPP connection, and, secondly, it uses IPSec for encryption. That is why L2TP is usually paired with IPSec, an encryption protocol, to secure the data passing the VPN tunnel. L2TP (Layer 2 Tunneling Protocol) is a VPN protocol derived from PPTP (Point-to-Point Tunneling Protocol) that does not offer any encryption by itself.
