If you’re wondering which VPN protocol uses UDP port 1701, the answer is L2TP. L2TP is a popular VPN protocol that uses both UDP and TCP ports to provide a secure and reliable connection.

A VPN, or Virtual Private Network, is a secure tunnel between two or more devices. A VPN encrypts all traffic going through it, making it safe and private. There are many different types of VPN protocols, each with its own advantages and disadvantages.
One popular VPN protocol is PPTP, which uses the TCP port 1723. PPTP is easy to set up and is therefore popular with home users and small businesses. However, because it uses the TCP protocol, it is not as secure as some other VPN protocols and can be blocked by firewalls.
Another popular VPN protocol is L2TP/IPsec, which uses the UDP port 1701. L2TP/IPsec is more secure than PPTP but can be slower because it uses the UDP protocol.
Which VPN protocol you use will depend on your needs. If speed is your main concern, then PPTP may be the best choice. If security is your main concern, then L2TP/IPsec may be the better choice.
What is UDP Port 1701?
UDP port 1701 is used by the Layer 2 Tunneling Protocol (L2TP), a tunneling protocol used to support virtual private networks (VPNs). When L2TP is used with the Internet Protocol Security (IPSec) protocol to create a VPN, the combination is usually referred to as L2TP/IPSec.
What VPN Protocols Use UDP Port 1701?
UDP port 1701 is commonly used by VPN protocols such as L2TP/IPSec and SSTP. This port is used for establishing and maintaining a secure connection between two devices.
OpenVPN uses UDP port 1701 by default. You can change the port number if you want, but it’s not necessary.
