Step 1. Create a Configuration File
OpenVPN uses configuration files (.ovpn) to determine how to set up the VPN connection. You'll need to create a new text file with the .ovpn extension. You can do this using any text editor, such as Notepad. Save this file in the OpenVPN's configuration directory, typically C:\Program Files\OpenVPN\config.
In the configuration file, you'll need to specify various settings for your VPN server. Here's a basic example of what your configuration file might look like:
# Specify the port number on which the server will listen
port 1194
# Specify the protocol (UDP is faster, but TCP is more reliable)
proto udp
# Specify the type of device. ‘tun' is used for routing, ‘tap' is used for bridging
dev tun
# Specify the location of the Certificate Authority file
ca “C:\\Program Files\\OpenVPN\\config\\ca.crt”
# Specify the location of the server certificate file
cert “C:\\Program Files\\OpenVPN\\config\\server.crt”
# Specify the location of the server key file
key “C:\\Program Files\\OpenVPN\\config\\server.key”
# Specify the location of the Diffie Hellman parameters file
dh “C:\\Program Files\\OpenVPN\\config\\dh2048.pem”
# Specify the VPN network. The server will take the first IP, and the clients will take the rest
server 10.8.0.0 255.255.255.0
# This file is used to keep track of the next IP address to be assigned
ifconfig-pool-persist ipp.txt
# This command pushes the client to redirect all traffic through the VPN
push “redirect-gateway def1 bypass-dhcp”
# These commands push specific DNS servers to the client
push “dhcp-option DNS 208.67.222.222”
push “dhcp-option DNS 208.67.220.220”
# This command helps in case of connection drops
keepalive 10 120
# This command specifies the encryption cipher
cipher AES-256-CBC
# These commands are used to drop privileges
user nobody
group nogroup
# These commands are used to keep the key and tun/tap device across VPN restarts
persist-key
persist-tun
# This command is used to write status to a file
status openvpn-status.log
# This command is used to set the log verbosity
verb 3
You can find ready-made sample configuration files in your OpenVPN directory. This directory is generally under the Program Files (not Program Files x86) folder.
Step 2. Generate Certificates and Keys
OpenVPN uses certificates and keys to secure the VPN connection. You'll need to generate a Certificate Authority (CA) certificate, a server certificate, and a server key. OpenVPN provides easy-rsa, a set of scripts to help you generate these.
If you're using an older version of the OpenVPN server, you can find these scripts in the C:\Program Files\OpenVPN\easy-rsa directory. If not, you have to download them from the GitHub repository.
Step 4. Start the OpenVPN Server
You're ready to start your OpenVPN server once you've created your configuration file and generated your certificates and keys.
Open the OpenVPN GUI by clicking on its icon in your system tray. Right-click the icon and select “Connect.” You should see a message saying the connection has been established if everything is set up correctly.
How to Connect to Your OpenVPN Server
Once you've successfully installed and configured your OpenVPN Server on your Windows machine, the next step is to connect to it. Here's a step-by-step guide:
Step 1. Install the OpenVPN Client
To connect to your OpenVPN Server, you'll need to install the OpenVPN Client on the device you'll be using to connect to the server. This could be another computer, a smartphone, or a tablet.
You can download the OpenVPN Client (OpenVPN Connect) from the official website. Make sure to choose the correct version for your operating system.
Step 2. Generate a Client Configuration File
Like the server, the client also needs a configuration file to connect to the server. You'll need to create a new .ovpn file with the correct settings for your server. This file should include the client certificate, key, and Certificate Authority (CA) certificate.
Once you've created this file, transfer it to the device you'll use to connect to the server.
Step 3. Import the .ovpn File and Connect to Your VPN
On the device you'll use to connect to the server, open the OpenVPN Client and import the .ovpn file you created in the previous step. This will create a new VPN profile.
In the OpenVPN Client, select the VPN profile you just created and click “Connect.” If everything is set up correctly, you can establish a secure connection to your OpenVPN Server.
