What Port Does a VPN Use?

Wish to establish a secure Internet connection? Then you should ensure that you have many options in case there are issues. One of the most popular ways to do this is to use a VPN that offers different protocols and uses different ports, such as VPN Unlimited.

But what’s the difference between various protocols and VPNs? What ports do VPNs use? And what ports does VPN Unlimited, a leading VPN provider, support? Let’s figure it all out! In this piece, we will take a look at the most popular types of VPN protocols, including L2TP/IPSec, OpenVPN® TCP/UDP, IKEv2, and WireGuard®. We will also explore their respective Internet Assigned Numbers Authority (IANA) designated VPN port numbers.

What Port Does a VPN Use

Here are the most common VPN protocols, along with the types of ports they use:

  • WireGuard - this is one of the youngest, fastest, and safest VPN protocols. It supports a wide range of ports. By default, WireGuard uses port 51820 UDP, though it can be configured to use other VPN port numbers if necessary.
  • L2TP (Layer Two Tunneling Protocol) - this one uses various port numbers as well; TCP port 1701, UDP port 4500, and UDP port 500. These common VPN ports are often used in combination with IPSec for added security.
  • IPSec (Internet Protocol Security) - IPSec uses UDP ports 4500 and UDP port 500. These ports are specifically designated for establishing a secure connection between your device and the VPN server.
  • OpenVPN - this VPN protocol is a popular option for when you need security and don’t mind sacrificing some performance. It uses UDP or TCP protocol uses on port 1194, as well as TCP port 443, which is often used for HTTPS traffic.
  • IKEv2 - this protocol is renowned for its fast performance. It uses UDP ports 4500 and 500, similar to IPSec, making it a reliable option for users seeking a balance between speed and security.
  • SSTP (Secure Socket Tunneling Protocol), a.k.a. SSL (Secure Sockets Layer) - uses TCP port 443, which is the same port commonly used for secure web browsing via HTTPS. This makes SSTP a good choice for environments where other VPN ports might be blocked.
  • PPTP (Point-to-Point Tunneling Protocol) - uses TCP port 1723. This protocol is quite ancient but still occasionally finds its use, e.g., for accessing a Microsoft RAS. However, it’s worth noting that PPTP is considered one of the more unsafe VPN ports due to its outdated security measures.

What Ports Does VPN Unlimited Use?

What is a VPN Port

VPN stands for Virtual Private Network. So a VPN port works similar to your common ISP (Internet Service Provider), but are not static and will often provide unique features. For instance, some support stronger data encryption, which protects your sensitive info from any third parties. Others offer enhanced mobility support, greatly improving your experience of using the VPN on your mobile device.

Basically, if the VPN is an extra layer for securing your data, then the port is the conductor for this secure connection. Here’s how a VPN connection works. A user launching a VPN on their device establishes a secure VPN tunnel through a VPN port. On the other side of the tunnel is the server you’re trying to access, with another port of its own. The specific VPN port numbers used can affect the performance and security of your connection. Choosing the right VPN port is crucial for maintaining both speed and security.

As the user establishes a secure connection, their web traffic is routed via these internet ports and data packets. This allows users concerned about their privacy and anonymity to hide their actions from unauthorized parties, be it their ISP, corporate networks, or even government agencies. No one will sniff out what you do online or what websites you visit - all thanks to VPN Unlimited and its commonly used VPN ports and protocols!

FAQ on What Ports VPNs Use

What ports need to be open for VPN?

It depends on the VPN protocol that’s being used. For instance, one could use open a UDP port for an OpenVPN connection. It’s also a good idea to implement TCP 443 as a fallback method, in case the user is on a public network where the connectivity is limited. TCP 443 is used for HTTPS traffic, which makes it a default port for a lot of websites. It’s easier for protocols that use a wide range of ports, such as WireGuard, as you have a broader set of options to choose from. However, it is essential to be aware of unsafe VPN ports that might compromise your connection.

What is a port in VPN?

As explained above, a virtual port that handles traffic tunneled through a VPN connection is called a VPN port. Your virtual private network establishes a virtual point-to-point tunnel that connects your device with the internet via a public connection. As a result, all data packets that your device sends through such a tunnel are encrypted, and your actual IP address is hidden. Properly configure your VPN to use the correct VPN ports for your needs to ensure both security and performance.

What is port 443 normally used for?

If one has only ever heard of a single VPN port number, it’s probably port 443. It, like any other virtual port, is used to direct internet traffic. Port 443 is arguably the most common - billions of people use it every single day. This is because all the web searches you make through HTTPS or HTTP browser connections go through this port. Through it, your device connects with a server that contains the information you requested. Because of its common use, port 443 is often considered one of the more secure connection options for VPNs.
