What Port Do VPNs Use?

When it comes to establishing a secure connection over the internet, you want to have as many options available as possible. There are countless types of VPNs that offer different protocols and ports. In this blog post, we will explore what some common types of VPN protocols are and which ports they use.

The list includes PPTP, L2TP/IPSec PSK (pre-shared key), OpenVPN TCP/UDP, IKEv2 UDP, and SSTP.

Below I’ve listed these VPN protocols with their corresponding port numbers:

  • PPTP (Point-to-Point Tunneling Protocol) – This protocol uses port 1723 TCP.
  • L2TP (Layer Two Tunneling Protocol) – This protocol uses port 1701 TCP, Port 500 UDP, and port 4500 UDP.
  • IPSec (Internet Protocol Security) – This protocol uses port 500 UDP and ports 4500 UDP.
  • OpenVPN – This protocol uses port 1194 TCP/UDP and port 443 TCP.
  • IKEv2 – This protocol uses ports 500 and 4500
  • SSTP (Secure Socket Tunneling Protocol) – This protocol uses port 443 TCP.

What is a VPN Port?

A VPN port is a Virtual Private Network port. It’s just like your traditional Internet Service Provider (ISP), but there are some really cool features that make it unique and special (like the encryption). You can think of a VPN as an extra layer for protecting your data when you’re browsing online or using other internet resources.

The “port” part of a VPN comes from how this type of connection works: A user logs on to their computer through one port in order to access another server via another different port. Basically, all traffic gets routed via these ports so that people who want privacy don’t have any worries about someone sniffing out what websites they visit while web surfing!

Unsafe VPN Ports to Avoid

The Internet Key Exchange (IKE) protocol uses Port 500. This is a popular VPN type, so it can be found in many different web browsers and operating systems. However, this port has known vulnerabilities that hackers have been able to exploit in order to gain unauthorized access to the system.

PPTP or Point-to-Point Tunneling Protocol also runs on ports 1723 through 1729. These are considered unsafe because they’re statically assigned by the service provider and require special configuration of firewalls along with other IT requirements from your computer’s network hardware manufacturer for proper implementation. If you do use these types of protocols then make sure that they don’t conflict with any other software running on your machine!

Here are some other ports you should avoid:

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

Why Use a VPN?

VPNs offer a number of advantages. They are most popularly used to access the Internet without getting caught (e.g., at work). A VPN can also help you stay safe by encrypting your data from one end to another so that no third party will ever have access to it and they’re also great for accessing websites or services which may be blocked in certain regions like Spotify, Netflix, Hulu Plus, Pandora Radio or even Facebook!

Some things do need to be considered when using a VPN though:

  • Privacy is an important consideration with any type of computer software but especially since this information includes anything about you including what sites you visit on a daily basis. You should use providers who keep NO logs whatsoever.
  • Speed is another important factor and you want a VPN that is lightning fast. You want to be able to download files and stream video without any interruption.
  • The cost is also something that you need to consider before subscribing to a VPN service provider because some providers offer monthly plans while others prefer an annual payment system which could mean saving money in the long run if they’re offering a good deal.
