πŸ¦‘Introduction to PPTP, L2TP and SSTP:

PPTP: Point-to-Point Tunneling Protocol

(PPTP: Point to Point Tunneling Protocol)
Default port number: 1723 (TCP) Point to Point Tunneling Protocol
(PPTP) is a network technology that supports multi-protocol virtual private networks. It works on the second layer. Through this protocol, remote users can safely access the company network through the Microsoft Windows operating system and other systems equipped with a point-to-point protocol, and can dial to connect to the local ISP and securely link to the company network through the Internet.

L2TP: Layer 2 Tunneling Protocol

(L2TP: Layer 2 Tunneling Protocol)
Default port number: 1701 (UDP)
L2TP is an industry-standard Internet tunneling protocol. Its function is roughly similar to that of PPTP. For example, it can also encrypt network data streams. However, there are also differences. For example, PPTP requires the network to be an IP network, and L2TP requires a point-to-point connection for data packets; PPTP uses a single tunnel, and L2TP uses multiple tunnels; L2TP provides header compression and tunnel verification, but PPTP does not support it.

About PPTP and L2TP

Both PPTP and L2TP belong to the second layer of tunneling protocols. The PPP protocol is used to encapsulate data, and then additional headers are added for data transmission on the Internet. Although the two protocols are very similar, there are still differences in the following aspects:


1. PPTP requires the Internet to be an IP network. L2TP only requires the tunnel medium to provide a packet-oriented point-to-point connection. L2TP can be used on IP (using UDP), Frame Relay Permanent Virtual Circuits (PVCs), X.25 Virtual Circuits (VCs), or ATM networks.

2. PPTP can only establish a single tunnel between two ends. L2TP supports the use of multiple tunnels between two ends. Using L2TP, users can create different tunnels for different quality of service.

3. L2TP can provide header compression. When compressing the packet header, the system overhead (overhead) occupies

4 bytes, while the PPTP protocol occupies 6 bytes4
. L2TP can provide tunnel authentication, while PPTP does not support tunnel authentication. However, when L2TP or PPTP is used together with IPsec, IPsec can provide tunnel authentication, and there is no need to verify the tunnel on the layer 2 protocol.

5. PCVPN customized login device supports PPTP and L2TP (IPSEC) key functions.

SSTP: Secure Socket Tunneling Protocol

SSTP can create a VPN tunnel transmitted over HTTPS, thereby eliminating many problems associated with VPN connections based on PPTP (Point-to-Point Tunneling Protocol) or L2TP (Layer 2 Tunneling Protocol). Because these protocols may be blocked by some Web proxies, firewalls, and network address translation (NAT) routers between the client and the server.

This SSTP is only suitable for remote access, and cannot support VPN tunnels between sites.
Microsoft hopes that SSTP can help customers reduce problems related to IPSec VPN when IPSec VPN connections are blocked by firewalls or routers. In addition, SSTP will not cause reservation problems, because it will not change the end user's VPN control. SSTP based on VPN tunnel can be directly inserted into the interface of current Microsoft VPN client and server software.
