Do you want to deploy a secure server on a VPS, organize a corporate network with secure communication with remote employees, or just need an encrypted data transfer on a personal device? In all cases, you need to use a VPN - a good example is OpenVPN. According to many experts, it's now the best incarnation of this technology: reliable, secure, and functional. And although it is easy to work with, first it is worth understanding what OpenVPN is, the pros and cons, how to install and configure.
OpenVPN is a protocol for implementing a VPN that provides both point-to-point and server-to-client connections. It was introduced in March 2002 as an open-source product and is regularly improved. It is based on SSL/TLS technologies with libraries like OpenSSL/PolarSSL, and UDP and TCP transport layer protocols are used for data transfer (the second is considered a bit more stable, and with the first higher speed, which makes it preferable). With OpenVPN, you can bypass the firewall and NAT, and it is almost impossible to detect and block because it is indistinguishable from normal HTTPS traffic. Because of all this, it has become one of the most popular solutions - not without reason VPN providers offer it in many default pricing plans.
Before telling you how to install OpenVPN, how to use it and how to configure it, it is worth understanding why we should do it at all. Therefore, we must point out the main advantages of this technology:
Separately, it is worth mentioning that OpenVPN is also easy to use. Yes, the fine manual configuration of the protocol may seem relatively complicated, but at a basic level, everyone can handle the installation and launch of the technology. In this case, the installation principle is the same - no matter what operating system is installed on the device. The only difference will be in the interface details, but the steps themselves are identical:
That's it, the installation is done and you know everything you need to know about OpenVPN: what it is and why it is there - so you can work in a safe environment! And if you want, you can configure autorun, UDP over TCP priority, block DNS leaks, or select the desired ports - and these are just a few examples of additional features… You can find all the details in the doc folder in the installation folder or in the Help guide on the official protocol website.
Let's speak at once: we are not going to describe in detail the scenario of creating a secure server with this protocol. Yes, it is also an important part of the topic of what OpenVPN is, but the task of raising such a VPN server is in fact a separate topic. Its scale can impress even a trained person! We will list only a part of the required work so that you can estimate the complexity of the project:
…and much more! And after all the procedures, you should test the hardware and get it up and running. Plus note: the implementation of each step is different on different server OS.
However, you can simplify such a project in some respects - if you contact HostZealot. We provide VPS for rent, which is optimally suited for various tasks, including organizing a VPN server with OpenVPN technology: they are fast and stable. In addition, we have a flexible pricing plan, as well as competent 24-hour technical support. They can always tell you how to set up a VPS or how to use OpenVPN, help with VDS monitoring - and answer any other questions!
