Greetings to all our readers who are looking to set up OpenVPN Server on Debian 7! In this comprehensive guide, we will walk you through the complete installation process and provide you with all the necessary information that you need to know about OpenVPN Server.
Introduction: What is OpenVPN Server?
OpenVPN Server is a widely used open source software that is used to create a secure virtual private network (VPN). It allows users to securely access their network resources from anywhere, even when they are not physically connected to the network. The main advantage of OpenVPN Server is that it provides a high level of security and privacy for users by encrypting their data and keeping it safe from prying eyes.
How Does OpenVPN Server Work?
OpenVPN Server uses a combination of virtual private networking (VPN) and secure socket layer (SSL) technologies to create a secure and private connection between users and their network resources. When a user connects to the network using OpenVPN Server, the software creates a secure tunnel between the user’s device and the network, encrypting all data that passes through the tunnel. This ensures that the user’s data is safe from hackers, cybercriminals, and other malicious entities.
What Are the Main Components of OpenVPN Server?
OpenVPN Server consists of several components that work together to create a secure and private VPN connection. These components include:

sudo nano /etc/openvpn/server.confThis will open the Nano text editor. Here, you can create the configuration file by adding the required settings and values.
Step 4: Generate Digital Certificates
The next step is to generate digital certificates for your OpenVPN Server. Digital certificates are used to encrypt data sent between the server and the clients and to authenticate clients when they connect to the server.
You can generate digital certificates by using the Easy-RSA tool. First, navigate to the directory where you want to store the certificates:
cd /etc/openvpn/easy-rsaThen, run the following command to initialize the Easy-RSA environment:
source varsFinally, run the following command to generate the certificates:
./build-key-server serverStep 5: Configure the Firewall
The next step is to configure the firewall to allow traffic to and from the VPN server. To do this, you need to allow UDP traffic on port 1194.
sudo ufw allow 1194/udpStep 6: Start and Enable OpenVPN Server
The final step is to start and enable the OpenVPN Server. To do this, run the following command:
sudo systemctl start openvpn@serversudo systemctl enable openvpn@serverOnce you have completed the above steps, you can connect to your OpenVPN Server from any device that has the OpenVPN Client installed.
