Are you looking to know what VPN port number your VPN uses?

Are you someone who wishes for better internet security?

If so, you have come to the right place.

In this article, we will deep dive into what port a VPN uses and the different kinds of protocols leveraged by different VPNs.

In this day and age of technological revolution, internet security is gaining more importance.

To protect your identity and data on the web, it is recommended that you use a VPN.

The good news is that if you want to establish a secure connection on the internet, you have endless options now.

VPNs use different kinds of ports and protocols and your internet security basically comes down to what kind of ports and protocols you are using.

Hence, here we will learn all about the different kinds of common VPN ports.

But, before we jump straight to all that, let us make sure that you have some rudimentary knowledge about how a basic VPN works and what protocols and ports actually mean. Let’s go.

What is a VPN?

VPN stands for Virtual Private Network. It is a service that creates an encrypted tunnel for your data.

It works just like your traditional ISP but what sets it apart is that it works towards protecting your private network connection when using public networks.

A VPN service disguises your online identity and makes sure that third-party entities cannot track your data.

It acts as an extra layer for protection over your data by hiding your IP address and encrypting your data.

What is a VPN Port Number?

Before you understand what a VPN port number is, it is essential that you learn what port number numbers are, in the first place.

Any device that is connected to an internet network has an IP address that is unique to that device.

Now, port numbers are basically trackers that identify the various processes that occur under each of these IP addresses.

Port numbers help software recognize data and perform the necessary action related to it.

In simple words, whereas an IP address is assigned to a specific device, port numbers are assigned to various functions and interactions within that particular device.

These numbers are intended to detect these operations on the web and assist the receiving end in identifying the operation and taking the appropriate response.

Every operation on the internet has been designated its own port number(s).

For instance, an FTP protocol uses port numbers 20 and 21.

When sending a file, the software recognizes the number, identifies where the data is meant to be sent, and then sends it off to the appropriate location.

Hence, port numbers essentially act like tunnels through which data transmission can be easily conducted on the internet.

Without these numbers, devices will fail to communicate with one another over the internet.

Now, a VPN port number works in the same way but in this case, it establishes a more secure connection between two points.

A user connects to the internet using one port so that they can access another server using another port.

Essentially, all VPN data is routed over these protected ports whenever users create protected VPN connections.

As a result, those who value privacy do not have to worry about their internet provider or corporate systems sniffing out which websites they access when browsing the web!

Which Is The Best VPN Port?

To know which is the best VPN port for you, you need to first learn what VPN ports are compatible with the router you are using.

VPN services use different protocols to create a safe connection on the internet and these protocols use some common VPN ports that you should know about.

Below we have made a table listing the different protocols and what ports they use. Refer to it to know which is ideal for you.

PPTP (Point-to-Point Tunneling Protocol)- It is one of the earliest VPN protocols and has two classifications under it- TCP, which is meant for the PPTP control path and GRE, which is meant for the PPTP data path.TCP port 1723, GRE port 47
L2TP (Layer Two Tunneling Protocol) – L2TP is an extension of PPTP that uses a number of VPN ports to establish a secure connection.TCP port 1701, UDP port 4500, and UDP port 500. The 4500 and 500 UDP ports are meant for negotiating IPsec keys.
IPSec (Internet Protocol Security) – It is a framework of open standards that ensure secure communication over Internet Protocol (IP).

This protocol usually protects sensitive data like medical records, financial transactions as well as corporate communications.
UDP port 4500 and UDP port 500.
OpenVPN – It is an open-source protocol, meaning that anyone can access the source code and the protocol is frequently tested by developers for flaws.

Many VPN services in the market use OpenVPN.
Ports 1194 UDP and 443 TCP
IKEv2- It is the second version of the Internet Key Exchange, as created by Microsoft and Cisco.

This protocol is responsible for request and response actions and sets up a SA (security association) in the IPSec.
UDP port 4500 and UDP port 500SSTP (Secure Socket Tunneling Protocol) – It is the next-generation VPN protocol introduced by Microsoft to replace PPTP and L2TP/IPSec protocols.Port 443 TCPWireGuard – It is the youngest VPN protocol.

It is a security-focused protocol that is meant for ease of use and high-speed performance.
UDP port 51820

Hence, in order to know what port does VPN use, you have to know what protocol it is using.

The above-mentioned ports are some of the most widespread and safe ones.

If your VPN is using these port numbers, you don’t have anything to worry about.

However, if you are using a free VPN service, your internet data is at risk since these free services do not usually use these common ports that are much safer.

In order to cut down prices, they go for ports that are easily accessible.

Hence, some of the VPN port numbers that you must avoid are TCP port 23, TCP port 21, TCP/UDP port 53, TCP port 1080, TCP port 80, and TCP port 4444.

When choosing a VPN service, it is recommended that you go for a premium one.

You can’t put a price on internet security and if you wish to have a top-notch secure connection, a free VPN is not the way to go.


In the table above, you must have already noticed the terms TCP and UDP. These are the different kinds of ports.

Let’s discuss the difference between them so that you have a better idea.

TCP: TCP stands for Transmission Control Protocol. It is a port that always creates endpoints between the two locations between transmitting any kind of data.

This port ensures that the data is always delivered to the intended recipient.

The port also records data to ensure that it is not lost, ensuring that it arrives safely at the receiving end. All these features make the TCP port more reliable.

It is used for tasks wherever secure transmission is the most important such as email applications or web browsing.

UDP: UDP stands for User Datagram Protocol. Unlike TCP, UDP ports do not establish any connection before transmitting.

This helps in reducing transfer speeds but the downside is that it makes the transmission less secure.

It does not examine data as extensively as TCP, therefore it is lighter and faster. As a result, sometimes data gets transmitted in the wrong sequence.

It is used for tasks wherever speed is critical, such as online gaming and video conferencing.

Why Is Knowing Your Port Number Necessary?

You must be wondering what is the point of knowing your port number.

Knowing your port number essentially gives you greater control over the software you use.

It can be useful when giving certain applications access or configuring firewalls since they can block some ports.

Hence, manually configuring them can come in handy.

You can also use port forwarding to configure ports and your router as this can help in increasing internet speed.

Why Should You Use a VPN?

VPNs have several advantages. These are most commonly used to avoid detection when using the Internet.

They encrypt your data making sure that you stay secure and safe.

These services track your data as it transmits between two points, ensuring that third-parties gain access to your data.

This reduces the vulnerability of your data and traffic to cyber threats.

You may also utilize a VPN connection to access content or services that may be prohibited in specific locations owing to a restricted firewall, such as Netflix, Pandora Radio, Spotify, Hulu Plus, or TikTok.

As a result, VPNs are required when you travel internationally for pleasure or work and wish to visit websites that you normally access at home.

But, with so many VPN services now available in the market, it becomes difficult for users to know which ones are the best.

We have compiled a list below of some of the best VPN services available so that you have an easier time picking the one that is perfect for you.
