How to Set Up OpenVPN on pfSense for Security

Setting Up Your Own OpenVPN Server on pfSense

When it comes to network security, setting up an OpenVPN server on pfSense is a game-changer. For those unfamiliar, pfSense is a robust, open-source firewall and router platform that offers extensive functionality beyond a typical consumer router. Unlike most routers, pfSense is regularly updated to address vulnerabilities, ensuring a secure and reliable connection. By configuring an OpenVPN server on pfSense, you can securely access your home network from anywhere. This guide simplifies the process, focusing on key steps and potential pitfalls.

Why Choose OpenVPN on pfSense?

Setting up an OpenVPN server on pfSense brings numerous benefits. It allows secure remote access to your home network, making it possible to use your home internet connection from remote locations. This setup also supports multiple device connections, offering an efficient alternative to running individual VPN clients on each device. Beyond the security advantages, pfSense enables easier management of firewall rules when handling multiple tunnels with distinct policies.

Authentication: Where to Begin

Before diving into the setup, it’s crucial to decide on an authentication method. pfSense supports password-based, certificate-based, or a combination of both. For simplicity and security, we’ll use both methods in this tutorial.

Generating the Certificate Authority (CA)

A Certificate Authority (CA) is essential for validating the OpenVPN server’s identity. Follow these steps:

1. Go to System > Cert. Manager.
2. Click Add to create a new CA.
3. Set the Method to Create an internal Certificate Authority.
4. Choose your preferred Key type (RSA or ECDSA).
5. Set the Key length to at least 2048 (4096 recommended).
6. Select a Digest Algorithm, sha256 or higher.
7. Save your settings to create the CA.

Creating the Server Certificate

Next, create a server certificate to authenticate the server:

1. In System > Cert. Manager, switch to the Certificates tab.
2. Click Add/Sign to create a new certificate.
3. Use the same key type and length as the CA.
4. Set the Lifetime to 365 days.
5. Define it as a Server Certificate.
6. Save the settings.

User Configuration

Now, let’s create a user for the OpenVPN server:

1. Navigate to System > User Manager.
2. Click Add and enter a username and password.
3. For certificate-based authentication, edit user settings to add a user certificate.

Establishing the OpenVPN Server

With authentication configured, it’s time to set up the OpenVPN server:

• Go to VPN > OpenVPN and click Add under the Servers tab.
• Set Server Mode to Remote Access (SSL/TLS + User Auth).
• Ensure cryptographic settings match the CA and server certificate.
• Input a unique IPv4 Tunnel Network, e.g., 192.168.2.0/24.

Configuring Firewall Rules

To permit traffic through your VPN, configure firewall rules:

• Allow outbound traffic by selecting Firewall > Rules and adding a rule under the OpenVPN tab.
• Open ports for incoming connections via the WAN interface.

Exporting Client Configuration

pfSense offers an export utility for client configuration:

1. Install it via System > Package Manager.
2. Once installed, export configurations from VPN > OpenVPN > Client Export.
