What is a Double VPN?

You wake up in the morning, reach for your phone, and immediately press the button to open the VPN app. You sign in and click Connect, followed by Confirm. Your device connects to the closest server and you can start using it without any hiccups. Sounds great, right? Unfortunately, there’s a catch. After using the VPN for a while, you realize that some websites just aren’t accessible via the tunnel. Luckily, there’s a solution: a double VPN. What is a double VPN? Let’s explore.

What Is The Difference Between A Single And Double VPN?

If you’re reading this, I assume you’re already familiar with VPNs. However, just to remind you: a VPN is a Virtual Private Network. In essence, a VPN creates a private tunnel between your device and one of a handful of data centers around the world. While on the surface this may sound like a VPN is just one thing, it’s actually a whole suite of security protocols that protect your data while you surf the web or stream Netflix shows. Let’s explore the difference between a single and double VPN.

Single VPN

A single VPN, or simply VPN, offers you a way to secure your connection to a remote server. When you first launch the app, it will ask you to enter a name (this can be anything you want), select a location, and then click Connect. As soon as you do this, your device will set up a secure connection with the intended server and you can start using the app. However, in most cases, this is just a taste of what a single VPN can offer. Let’s take a closer look at the different types of VPNs and the pros and cons of each one.

L2TP/IPSec VPN

We’ll begin with the most popular and, in many cases, the most secure type of VPN. It’s been around since the 1990s and is considered a standalone VPN solution that can provide the best of both worlds: the speed of an IPSec connection coupled with the security of a PPP connection. That is, while L2TP/IPSec VPN provides fast, secure data transfers, it cannot provide end-to-end encryption. If you’re looking for total security, then you should look elsewhere.

OpenVPN

OpenVPN is another popular choice among VPN users. Like L2TP/IPSec, it can provide great speeds coupled with strong security. However, what sets OpenVPN apart from the rest is its adaptability. If you’re a software developer or a network engineer, you can take advantage of the OpenVPN SDK to create a server or client on the fly. To use OpenVPN, you’ll first need to install the app on your phone or other device, then launch it and enter a name (this can be anything you want) and the server address (a numerical IP address, usually between 224.0.0.0 and 239.255.255.255). Once these settings are complete, you can click Connect to access the server. From there, you can start using OpenVPN just like that!

If you’re looking for a solid VPN solution with all the important features you need, then OpenVPN is certainly worth a try. However, if you’re looking for end-to-end encryption, you should look elsewhere.

PPPoE VPN

If you have a router that supports IPv6 networking, you can use it to create a VPN with little to no effort. All you need to do is configure port forwarding on your router to forward TCP connections to your computer’s IP address to a certain port (usually 443 or 5223). Then, on your device, you’ll launch the VPN app, enter your username and password, and click Connect. Assuming everything goes smoothly, you should now be connected to a PPPoE server and able to use the app just as you normally would. The only difference is that, now, your device will appear to be originating the connection.

IPsec-IKEv2 VPN

If you have a router that supports IPsec (Internet Protocol Security), you can use it to create a VPN with little to no effort. All you need to do is install a VPN server on your device (most routers have this capability built-in), configure the VPN server to use IKEv2 for cryptography, and then connect to the VPN server with your device. From there, you can start using the app just as you normally would.

While IPsec-IKEv2 VPN offers great security, it’s not always the fastest option. In most cases, it’s slightly slower than a regular VPN. Still, it’s a secure and simple option for those looking for a free VPN solution.

Chameleon VPN

Chameleon VPN is a free VPN solution that, in most cases, offers some of the best speeds among the various free VPNs. Similar to OpenVPN in that regard, you’ll first need to install the app on your phone or other device, then launch it and enter your username and password. However, unlike OpenVPN, where you can launch an instance of the app anytime you want and connect to a server whenever you like, with Chameleon VPN, you’ll only be able to connect to chameleonvpn.com through the app. This way, you can ensure that your connection is secure.

Managed VPN

Managed VPN is, in many ways, the successor of traditional VPNs. Instead of using a PPPoE server to connect to a remote VPN instance, you’ll instead need to login to a managed VPN server. Much like a roving user who has logged in to a VPN before, you’ll be presented with a menu of VPNs that are available to you. From there, you can connect to the one that you need. Once that’s done, you can use the app just like you normally would. It’s probably the best choice for users who want to ensure their data is always secure while using public Wi-Fi or unsecure networks like the GitHub network or Twitch.

Why Should You Try A Double VPN?

So you’ve decided to try a VPN. Great! There are several different types of VPNs, all with their perks and quirks. If you’re looking for a fast, free solution, then you should look into trying one of the VPNs listed above. However, if you’re looking for enhanced security, then you should look into trying a double VPN. Why is that? Let’s explore.

Double VPN Provides Greater Security

While a single VPN provides security via PPPoE (Point to Point Protocol over Internet Protocol), IPSec, or OpenVPN, a double VPN provides additional security via IPsec or IKEv2. That is, a double VPN is capable of providing end-to-end encryption. It may not be the most popular choice, but, for those who need it, a double VPN is the clear choice.

Faster Data Transfers

Remember when I said that speed is a key consideration for anyone using a VPN? It is, and it doesn’t just relate to downloads. While you’re connected to a double or managed VPN, everything you do on your device will be encrypted. This means that, while your device is connecting to the VPN server, nothing can be sniffed out (except for technical measures) and no malware can be installed on your device. This also applies when you’re using public Wi-Fi or unsecure networks. Remember: your device will appear to be originating the connection, so no one else will have access to your data! This alone can save you from a variety of threats. For example, if you’re connecting to a VPN in Germany, but you’re sending emails from an email account in India, then the SMTP (Standard Mail Transfer Protocol) server in Germany might be able to be tapped. That is, it’s possible that a 3rd party could intercept your data as it travels between India and Germany.
