The protocol works with the IPSec authentication suite to encrypt and encapsulate data. L2TP/IPSec provides a much more secure and reliable connection than PPTP.
Port Configuration: Utilizes UDP 500, Protocol 50, UDP 1701 and UDP 4500. SYNOLOGY VPN PLUS ENCRYPT ALL DATA MAC
Compatible with: Microsoft Windows XP/7/8,10, Linux, Android, Apple iOS, and Mac OSX. Built-in clients and support for L2TP/IPSec is also available in all modern devices/operating systems out of the box. VPN Speeds: Slightly slower when compared with PPTP and OpenVPN. Uses double encapsulation of data for better security. 
Encryption Type/Level: Supports up to 256-bit session keys using the IPSec protocol, however, the session keys can vary depending on the algorithms being used. Layer 2 Tunnel Protocol (L2TP) is a popular method for establishing VPN connections and is provided as an option by most Internet service providers (ISPs). More recent protocols include Lightway and Wireguard, which are cutting edge new technologies hoping to bring VPN use to new levels, while PPTP is an obsolete protocol best avoided. This is done to avoid a mismatch between the protocol configurations of the VPN and the target server and ensure that your data arrives at the target server correctly.ĭifferent protocols include L2TP, OpenVPN, and IKEv2/IPSec, which are tried and true Virtual Private Network protocols used in order to establish a fast, secure, and reliable connection between two nodes. The process takes user data packets and places them inside another data packet. Together, these channels work to ensure that your data travels securely.įirst, the VPN Protocol performs a process called encapsulation when the connection is established. The control channel verifies the connection between your device and the server, while the data channel transmits the data. VPN protocols consist of two channels: a data channel and a control channel.
