If you’re looking for a VPN protocol that uses UDP port 1701 and doesn’t provide confidentiality, you’ve come to the right place. In this blog post, we’ll discuss which VPN protocols use UDP port 1701 and why this might be the right choice for you.

uUDP port 1701 is not a VPN protocol. A VPN protocol uses this port to establish a secure connection. There are many different types of VPN protocols, but not all of them provide confidentiality. Some of the most popular protocols that do provide confidentiality are PPTP, L2TP, and OpenVPN.
L2TP/IPSec is a popular VPN protocol that uses UDP Port 1701 and does not provide confidentiality by itself. However, L2TP/IPSec can be used in conjunction with IPsec to provide confidentiality. L2TP/IPSec is often used by remote workers and businesses to connect to their office networks.
Point-to-Point Tunneling Protocol (PPTP) is a method for implementing virtual private networks. A VPN is a private network that uses a public network (usually the Internet) to connect remote sites or users together. Instead of using a dedicated, real-world connection such as leased line, a VPN uses “tunneling” to encrypt data and send it via the Internet or another intermediate network.
For example, when you use your Web browser to access a secure Web page, your browser first connects to the Web server using PPTP. The data from your browser to the Web server are then encapsulated with additional headers that provide routing information. The data are then sent across the Internet to your organization’s VPN server where they are de-encapsulated and forwarded to the intended destination on your organization’s network.
Unlike other tunneling protocols, such as L2F and L2TP, PPTP doesn’t require installation of any additional software on the client computer. All you need is the Microsoft Point-to-Point Encryption (MPPE) protocol driver, which is built into Windows 95 and later versions.
Secure Socket Tunneling Protocol (SSTP) is a VPN tunneling protocol designed by Microsoft Corporation, and generally considered to be more secure than PPTP. Commonly used on Windows Vista, Windows 7, Windows Server 2008, and Windows Server 2008 R2, SSTP uses port 443 to encapsulate and transmit VPN traffic. As a result, SSTP is able to bypass many network restrictions that would normally block a PPTP connection, such as NAT firewalls and network edge traversal issues.
However, like all Microsoft products, SSTP suffers from a number of security vulnerabilities. One such vulnerability is the MS-CHAP v2 flaw that allows attackers to brute force passwords and gain access to user accounts. Another is the man-in-the-middle attack vector that can be used to decrypt and read VPN traffic. As a result, many security experts recommend using L2TP/IPsec or OpenVPN instead of SSTP whenever possible.
IKEv2 is a VPN protocol that uses UDP port 500. IKEv2 is an extension of the Internet Key Exchange (IKE) protocol and uses a stronger encryption method. IKEv2 does not provide confidentiality by itself, but it can be used in combination with IPsec to provide confidentiality.
UDP Port 1701
What is UDP Port 1701?
UDP port 1701 is used by the Layer 2 Tunneling Protocol (L2TP). L2TP is a tunneling protocol that is used to encapsulate Point-to-Point Protocol (PPP) traffic over an Internet Protocol network. It does not provide confidentiality or strong authentication by itself. However, it can be used in conjunction with IPsec to provide these features.
How is UDP Port 1701 used?
UDP port 1701 is used by the VPN protocol L2TP. L2TP is a tunneling protocol that is used to encapsulate another protocol, typically PPP. L2TP does not encrypt or provide confidentiality on its own, but it can be used with IPSec for encryption.
Does UDP Port 1701 provide confidentiality?
UDP port 1701 does not provide confidentiality. VPN protocols that use UDP port 1701, such as L2TP/IPsec, do not provide confidentiality by themselves. In order to achieve confidentiality, these protocols must be used in conjunction with a security protocol that provides confidentiality, such as IPSec.
At the end of the day, there is no perfect VPN protocol. Each has its own advantages and trade-offs. In general, though, we recommend OpenVPN or IKEv2/IPsec for most users. UDP port 1701 is not associated with any particular VPN protocol, but it is a common port used by many VPN providers.
