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 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 ports.

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 UDP port 51820.
• L2TP (Layer Two Tunneling Protocol) - this one uses various port numbers as well; TCP port 1701, UDP port 4500, and UDP port 500.
• IPSec (Internet Protocol Security) - IPSec uses UDP ports 4500 and UDP port 500.
• 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 protocols on port 1194, as well as TCP port 443.
• IKEv2 - this protocol is renowned for its fast performance. It uses UDP ports 4500 and 500.
• SSTP (Secure Socket Tunneling Protocol), a.k.a. SSL (Secure Sockets Layer) - uses TCP port 443.
• 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.

What Ports Does VPN Unlimited Use?

VPN Unlimited is a cutting-edge application, so it offers its users a wide range of VPN protocols. Check out this page for the complete list. As a result, VPN Unlimited can use various internet ports, depending on the protocol you’re using. Even better, you are free to switch protocols on the fly, flexibly changing ports to best suit your needs.

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 security. Here’s how a VPN connection works. A user launching a VPN on their device establishes a secure 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. 

As the user establishes a secure VPN connection, their web traffic is routed via these internet ports. 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 internet ports!
