Program Those Who Want to Install a VPN Should Know: OpenVPN

When you hear VPN, do you first think of connecting to another country, changing your IP address, or browsing the internet more privately?

What if I told you that you can securely connect to your home computer from anywhere in the world, access files at work while away, or connect two different networks?

Today we're reviewing OpenVPN. But let's clear up a misunderstanding from the start: OpenVPN is not a classic VPN subscription that automatically sends you to Germany or America when you turn it on and connect.

This software is a technology used to establish secure VPN connections. When configured correctly, it can become a very powerful tool for both individual users and businesses.

So what does OpenVPN do, is it free, how is it used, and does it really need to be on everyone's computer? Come, let's examine it together!

🔐 What is OpenVPN?

OpenVPN is an open source VPN protocol and software ecosystem used to establish secure connections over the internet.

VPN, a virtual private network, can create an encrypted connection tunnel between your device and the network or VPN server. Data sent over this tunnel makes it difficult for third parties on the network to directly read the traffic on a properly configured connection.

OpenVPN; certificates help secure the connection through authentication methods and encryption mechanisms.

For example, imagine you are connecting to a public Wi-Fi network in a cafe. A properly configured VPN connection can encrypt traffic between your device and the VPN server, making it difficult for people on the local network to read that traffic.

But there is an important detail: VPN does not make you completely invisible on the internet. Services you connect to can recognize your identity, browser cookies can track you, and the VPN provider or server administrator may see some connection information depending on configuration.

The real power of OpenVPN is that you can customize the secure connection according to your needs.

🧩 Are OpenVPN Connect and OpenVPN the same thing?

This is where many people go wrong.

There are different products in the OpenVPN ecosystem:

OpenVPN Community Edition: Free and open source VPN software. Suitable for those who want to set up their own VPN server, manage connections and configure their network according to their needs. However, it may require technical knowledge and management effort.

OpenVPN Connect: Official client application used to connect to OpenVPN compatible servers. It has options for Windows, macOS, Linux and mobile platforms.

OpenVPN Access Server: Commercial solution that makes it easier to set up a VPN service on your own infrastructure and offers web-based management interface and user management features.

OpenVPN CloudConnexa: Corporate connection solution offered via the cloud, which can be considered when you do not want to manage the server infrastructure yourself.

So just because you download the OpenVPN Connect app doesn't automatically mean you have a VPN service to use. You'll need to get a connection profile from a VPN provider or set up your own server.

🚀 1. You can set up your own VPN server

This is one of the most powerful uses of OpenVPN.

Let's say you have a computer at home that you keep open all the time or a server connected to the internet. You can set up a VPN server on this device with the appropriate configuration.

You can then connect to this server from your phone or laptop while you're out and about.

As a result, depending on your configuration, you can access devices on your home local network or route internet traffic through your home connection.

For example, he has a file server in his home. When you travel, you can access your files over a secure VPN connection with the appropriate network permissions and routing settings.

But just installing the program is not enough. Server settings, authentication, firewall, routing and modem configuration when necessary are also important.

🏢 2. You can remotely access the computer or files at work

OpenVPN is not just a tool for tech enthusiasts.

It can be very useful especially for remote workers, software developers, system administrators and businesses.

For example, a file server located on the company's internal network can only be accessed from within the office. You need to access these files while you are on a business trip.

If the company has an OpenVPN infrastructure, you can connect to the VPN using the authorized connection profile and access authorized resources remotely.

The important detail here is that a VPN connection does not automatically give you access to all computers. Access depends on authorization and network rules on the server.

In this way, businesses can use a controlled connection method instead of exposing private network resources directly to the internet.

🛡️ 3. Can provide additional protection on public Wi-Fi networks

When using public Wi-Fi in places such as airports, hotels or cafes, you may not be sure of the security of the network.

When connected to a trusted VPN server with OpenVPN, the connection between your device and the server may be encrypted. This is especially useful when communicating over untrusted networks.

But don't think of VPN as a shield that solves all security problems.

If you click on phishing links, download malware, or enter your password on a fake website, VPN alone can't protect you. HTTPS connections continue to be important.

You also need to trust the VPN server itself. Connecting to a free server where you don't know who it belongs to may not be as good an idea as you think in terms of privacy.

🌍 4. Can it change the IP address?

Yes, your externally visible IP address may change depending on how the connection is configured.

For example, if you connect to a VPN server located in another country and route all your internet traffic through that tunnel, the websites you visit will typically see the VPN server's exit IP address instead of your home connection's IP address.

But the critical point here is that OpenVPN alone does not provide you with a server in another country.

You must have access to a server located in another country or use a suitable VPN service. If you are connecting to the server at your own home, your IP address visible from the outside will mostly belong to your home internet connection.

Moreover, changing your IP address does not mean that you are completely anonymous on the internet.

⚙️ How to use OpenVPN?

There are two different scenarios for first-time users: Connecting to a VPN provider or setting up your own server.

Method 1: Connecting to a ready VPN server

1. step: Download the OpenVPN Connect application from its official website.

https://openvpn.net/client/

2. step: Install and run the application on your computer.

3. step: provided by the VPN provider or system administrator .ovpn. This file contains information such as the server to connect to and connection settings.

4. step: Add the file using the profile import option in OpenVPN Connect. Some services may provide a link address instead of a profile file.

5. step: Enter user information, certificate, or other authentication information if necessary.

6. step: Start connection. Check that the connection is successful from the status indicator in the application.

That's it! However, for the connection to work, the server must be accessible and the profile must be configured correctly.

Method 2: Setting up your own VPN server

If you want to manage your own server, you can consider OpenVPN Community Edition or Access Server options, which make management easier.

The general process in this scenario is as follows:

• Prepare a suitable server or computer.

• Install OpenVPN server software.

• Configure certificates and authentication settings.

• Set firewall, connection ports and network routing correctly.

• Create connection profiles for clients.

• Perform access and security tests by connecting from client devices.

This method provides more control; however, it can open a misconfigured server network to unnecessary risks. You should be especially careful when opening the server's administrative access to the internet.

🏁 Final verdict: Is OpenVPN worth using?

I think the biggest advantage of OpenVPN is its flexibility and the ability to set up your own VPN infrastructure.

If you just want to download an app and connect, you should know that OpenVPN Connect alone will not be enough. But if you have a VPN provider, are connecting to your workplace VPN system, or want to set up your own server, it's a pretty strong option.

The fact that it is free and open source is also an important advantage for users with technical knowledge.

However, if you are using a security tool, you should take updates, authentication and access permissions seriously, as well as installation.
