Do you need a VPN protocol that uses UDP port 1701 and doesn’t provide confidentiality? Check out our blog post to learn which VPN protocol is right for you.

There are a lot of different VPN protocols out there, and it can be tough to know which one is right for you. UDP port 1701 is one of the most popular VPN protocols. It’s known for being fast and reliable. However, it doesn’t provide confidentiality or encrypt your data. If you’re looking for a VPN protocol that does provide confidentiality and encryption, you might want to consider a different protocol.
L2TP/IPsec is a popular VPN protocol that uses UDP port 1701. L2TP/IPsec does not provide confidentiality or strong authentication by itself. However, it can be combined with other protocols to create a secure VPN. For example, L2TP/IPsec can be used with Microsoft Point-to-Point Encryption (MPPE) to provide confidentiality.
L2TP/IPsec is also often used with Internet Protocol Security (IPSec) to provide strong authentication and encryption. IPSec is a security protocol that can be used to protect communications over untrusted networks like the Internet. When combined with L2TP/IPsec, IPSec provides a complete VPN solution that can be used to securely connect remote users to a corporate network.
OpenVPN is a Cost-effective, feature-rich and secure VPN protocol. It uses UDP port 1701 and provides encryption, making it more secure than PPTP. However, it does not offer the same level of confidentiality as L2TP/IPSec or SSTP.
Point-to-Point Tunneling Protocol (PPTP) is one of the most commonly used VPN protocols. It uses a slightly different approach from other protocols, such as L2TP/IPsec, in that it uses a single TCP connection to set up a tunnel between the client and server. PPTP is faster and easier to configure than other protocols, making it a popular choice for users who need to set up a VPN quickly. However, PPTP does not provide the same level of security as other protocols, and it is not recommended for use in high-security environments.
UDP Port 1701
L2TP/IPsec (Layer 2 Tunneling Protocol with Internet Protocol Security): L2TP is a combination of PPTP and Cisco’s L2F protocol. L2TP uses UDP port 1701. L2TP does not provide confidentiality or strong authentication by itself. IPsec is typically used for these purposes.
The Layer 2 Tunneling Protocol (L2TP) is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by ISPs. It does not provide confidentiality or strong authentication by itself. Rather, it relies on an encryption protocol that it passes within the tunnel to provide privacy.
A main mode of L2TP operates in two phases:
Phase 1 – The L2TP control connection is established between an L2TP manager/server and client. A built-in security association (SA) is used for this phase. This phase requires only a single UDP port, 1701, to be open on any firewall between the two devices.
Phase 2 – After the tunnel has been established, data packets (L2TP messages) are exchanged between client and server, encrypted with IPSec.
OpenVPN is a VPN protocol that uses UDP port 1701 and does not provide confidentiality or strong authentication by itself. It is often used with IPsec for these purposes. OpenVPN is a free and open-source software application that implements virtual private network (VPN) techniques to create secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. It uses a custom security protocol that utilizes SSL/TLS for key exchange. It is capable of traversing network address translators (NATs) and firewalls. It was written by James Yonan and is published under the GNU General Public License (GPL).
Point-to-Point Tunneling Protocol (PPTP) is a method for implementing virtual private networks. A VPN is created by establishing a virtual point-to-point connection through the use of dedicated connections, virtual tunneling protocols, or traffic encryption.
PPTP uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets. The GRE protocol is described in RFC 1701. PPTP has been assigned the port number 1701 by the Internet Assigned Numbers Authority (IANA).
GRE is often not supported by firewalls, making PPTP less useful for site-to-site VPNs. In addition, PPTP uses the MS-CHAP v2 authentication protocol, which has been demonstrated to have security vulnerabilities. As a result, many VPN providers have stopped offering PPTP connections.
The UDP port 1701 is a VPN protocol that uses the UDP port. This protocol is used to provide confidentiality and integrity for data transmissions. It is also used to provide authentication for data transmissions.
L2TP/IPsec is a combination of the Point-to-Point Tunneling Protocol (PPTP) and Layer 2 Forwarding (L2F), with some improvements. L2F was developed by Cisco Systems, while PPTP was developed by Microsoft. Like PPTP, L2TP uses the UDP port 1701 for communications.
Both L2F and PPTP use the Password Authentication Protocol (PAP) for authentication and MS-CHAPv2 for key exchange. L2F also uses Layer 2 Forwarding, which is similar to Frame Relay or Asynchronous Transfer Mode (ATM), to provide data confidentiality and integrity. However, L2F has some security weaknesses that make it less secure than PPTP.
L2TP/IPsec addresses these weaknesses by using stronger encryption algorithms, such as Advanced Encryption Standard (AES), and by authenticating both the user and the server with digital certificates or Pre-Shared Keys (PSKs).
OpenVPN uses UDP port 1701 and does not provide confidentiality or message integrity by itself. However, it can be combined with an authentication layer such as SSL/TLS to provide those features.
Point to Point Tunneling Protocol (PPTP) uses a UDP Port 1701 and does not provide confidentiality or strong authentication by itself. However, PPTP can be used in conjunction with Layer 2 Tunneling Protocol (L2TP) to provide a more secure connection.
