Double VPN allows you to increase your security while connecting to a VPN. Learn about this VPN approach and its advantages.
What is Double VPN?
Double VPN is a technology allowing you to browse securely and anonymously by connecting to a chain of servers inter-connected via VPN-tunnel. When the user is connected a Double VPN server the traffic is redirected to a second server, with all the traffic subjected to several encoding steps. Thus, the intermediate server is only used to ensure pass-through traffic but not the connection to external network.
The working principle is rather simple. Firstly, the VPN client/app connects to a VPN server which then routes all traffic to another VPN server from where the destination is reached. The traffic is double encrypted within the two VPN layers before getting to the desired website.
Your computer >> First VPN server >> Second VPN server >> Destination
Advantages and disadvantages of using Double VPN
You may not need using a Double VPN if you simply want to unlock inaccessible services in your country (e.g.: Facebook, Twitter, etc.). But, when it is about high level of anonymity, double VPN can be of great help.
The main advantage of this approach is that the traffic between your device or computer to the desired destination is doubled encrypted. Thus, it is harder to be detected and decoded. Plus, your visible IP address is supplementary protected.
You may already guess the disadvantage: the double encryption slows the connection. However, in some cases, the connection between the VPN servers can be so optimized that compensates the time lost due to encryption/decryption process.
To sum up, double VPN is good for high security, but it is not recommended for unblocking restricted websites.
How to get it?
There are two ways to get and use a it: use two VPN services (preferably from different providers) or use a VPN service that offers Double VPN as a service.
Setup your own Double VPN
You may find below a possible scenario for setting up your own double VPN. You need two VPN accounts and a router. If you are looking for good VPN providers here are some that I recommend: HideMyAss and ibVPN.
1. Setup the first VPN on your router. This will be your hardware VPN.
2. Start the second VPN from your device or computer (using your Windows/MacOS/iOS/Android Internet Connection settings, or a VPN software). This will be your software VPN.
3. By connecting to the software VPN, your connection will be also encrypted by the hardware VPN, obtaining the double VPN.
Double VPN providers
There are VPN services that offer Double VPN as a service. They use VPN servers that are connected to each other and double encrypt the traffic. The advantage of this approach is that, firstly, you need to purchase only one VPN service and secondly, you connect to it in the same way you connect to the single VPN.
One such provider is NordVPN with the following nodes (entry/exit):
- Lithuania – Latvia -> lt-lv1.nordvpn.com
- Netherlands – Russia nl1-ru1.nordvpn.com
- Netherlands – United Kingdom nl-uk1.nordvpn.com
- Russia – Netherlands ru-nl1.nordvpn.com
- Taiwan – Hong Kong tw-hk1.nordvpn.com
- United Kingdom – Netherlands uk-nl1.nordvpn.com
How to check your Double VPN?
In order to check if you are really connected to a double VPN you may perform a simple test: click Start – Run , type the cmd. In the window that opens, enter tracert google.com. You will see the entire route that passes traffic, including through the servers you have selected. After you do the test without being connected to the VPN, you should do it again when connected. Check the differences. You should see additional entries corresponding to the two VPN servers your traffic being routed to.
