What Ports Does VPN Use (A Complete Guide)

Have you ever wondered what ports VPN use? If not, then you’re supposed to find out. VPN, or Virtual Private Network, is a technology that creates a secure connection over a public network such as the internet. VPNs are used to protect confidential data and allow for private communication. 

The Best Ports for VPN are:

  • Port 1723 TCP for the Point-to-Point Tunneling Protocol (PPTP).
  • L2TP uses the ports 1701 TCP, 500 UDP, and 4500 UDP for its communication protocol.
  • Ports 500 UDP and 4500 UDP are used for Internet Protocol Security (IPSec).
  • TCP port 443 is used by the Secure Socket Tunneling Protocol (SSTP).
  • Ports 1194 UDP and 443 TCP for OpenVPN.

Additionally, many VPN clients will support custom port configurations in order to maximize security and throughput.

Whether you need to connect to servers at work from home or access sensitive data remotely, VPN technology provides an easy and secure way to stay connected.

A Guide: What Ports Does VPN Use

VPN, or Virtual Private Network, is a technology used to create secure and private networks over public networks such as the internet. Users can establish secure remote access between two PCs with the help of a VPN. it can even be done for the entire internal network. 

There are different types of VPNs that use different ports in order to function. The most common type is IPSec VPN, often used when connecting other enterprise networks via the internet. Ports 500 and 4500 are commonly used by this type of VPN, while others may rely on port 1723. 

Another type of VPN is L2TP or Layer 2 Tunneling Protocol, which also makes use of port 1723 for tunnel setup. Additionally, PPTP or Point-to-Point Tunneling Protocol also uses TCP/IP port 47 and GRE tunneling port 47 to make a secure connection through the internet. 

Whether you need remote access to sensitive files from your home computer or want to securely connect multiple company branches together via the internet, VPN offers simple means for doing so that are widely available and fairly easy to set up.

What Is Port Forwarding?

Port forwarding is a technique that is commonly used in VPNs to allow traffic to be routed through a specific port on a server or other network device. Normally, all traffic would be routed through the default port of the network device. 

However, port forwarding allows users to specify which particular port they would like their traffic sent through. This can be useful for several reasons, including increasing security by allowing only certain types of traffic to pass through the specified port. 

Or improving performance by sending high-bandwidth applications such as streaming media over a different port than usual. Regardless of the specific use cases, understanding how VPNs use port forwarding is an important part of working with these networks effectively.

What Ports Ought To Be Avoided?

You cannot rely on any VPN port to be 100% secure. There are several ports and protocols with various levels of security available. Naturally, the most popular VPN ports will have strong security measures. After all, a high-end product calls for high-end service.

However, the risks become clear right once when someone uses a free VPN. Free VPNs might try to save money by employing less-secure protocols, which is typically done in an effort to save costs. If your VPN uses any of the following ports, you should probably think twice before paying for a premium VPN.


  • TCP port 21
  • TCP port 23
  • TCP/UDP port 53
  • TCP port 80
  • TCP port 1080
  • TCP port 4444

You cannot cut shortcuts when it comes to your internet security and privacy. Make an informed selection about the VPN service you want to use by doing your research.

The reason NordVPN is the best VPN in the world is because of its unmatched and unequaled coverage. You’re never too far from a safe and secure internet connection thanks to our 5200+ servers spread throughout more than 60 nations.

What are Port Numbers?

Port numbers are numerical values that a VPN client uses to identify its communication with different types of servers. For example, port number 21 is used for FTP traffic, while 53 identifies DNS server traffic. 

In general, each port has certain characteristics that differentiate it from other ports, including the protocols it supports, how much bandwidth it can handle, and how secure it is. 

By choosing the appropriate port number for your VPN connection, you can optimize your network performance and keep your data safe from external threats. 

Whether you are setting up a new VPN or looking to troubleshoot an existing one, understanding how port numbers work is an essential first step.

FAQs: What Ports Does VPN Use

Q 1: Do VPN Open Ports?

A 1: When using a VPN, device transmission is encrypted and the data packet is tunneled through secure servers. Port forwarding is by default disabled while using a VPN. The VPN will immediately shut all opened ports. However, if you use a VPN with port forwarding, you can keep those ports open.

Q 2: What UDP Port Is Used For A VPN?

A 2: The Point-to-Point Tunneling Protocol (PtPTP) is expanded upon by the Layer Two Tunneling Protocol (L2TP), which uses UDP port 1701. IPSec and L2TP are frequently combined to create virtual private networks (VPN). IP protocol 47 Generic Routing Encapsulation and TCP port 1723 are used by the Point-to-Point Tunneling Protocol (PPTP) (GRE).

Q 3: How Do VPN Ports Operate?

A 3: VPN port forwarding reroutes the incoming connections to get over the NAT firewall and speed up connections. In many situations, VPN port forwarding might be useful. It allows you to remotely access your computer when you’re not at home and can speed up torrent downloads.

Wrapping Up

The VPN ports are important to understand in order to set up the VPN connection. By knowing which TCP and UDP ports to use, you can ensure that your traffic is being routed through the VPN and not exposed to potential security risks.
