2.2 Navigating to the Certificate Manager
Once logged in, navigate to the System
menu and then select Certificates
.
2.3 Creating a New Certificate
Click the Add
button to create a new certificate. You’ll need to provide a descriptive name for the certificate (e.g., “pfSense Self-Signed”). Choose “Internal CA” for a self-signed certificate. You must then specify a valid Common Name (CN), which is typically your firewall’s internal IP address. You can include additional Subject Alternative Names (SANs) if needed to cover other domain names or IP addresses. [Internal link to pfSense documentation on configuring certificates]
2.4 Generating the Private Key and Certificate
Click “Save” to generate the private key and certificate and complete the process. You’ll now have a private key and a self-signed certificate created within your pfSense firewall. Remember to keep these details secure!
3. Installing Your SSL Certificate on Your pfSense Firewall
Once the certificate is created, the next step is to install it on the relevant services which need to be secured. This involves associating the created certificate with the services such as the pfSense web interface, VPN services, or any other custom services that require HTTPS encryption.
3.1 Configuring the pfSense WebGUI
The pfSense web interface is usually configured to use a self-signed certificate by default, especially when generated using the internal CA. You can verify this in the System > General settings menu. Some pfSense upgrades might require certificate assignment.
3.2 Configuring Other Services
Other services, such as OpenVPN or custom services, have their own configurations. For these, you will need to specify the certificate and private key during their setup. Remember to follow the specific documentation for each service on how to apply your new certificate.
4. Obtaining and Installing a Let’s Encrypt Certificate on pfSense
Let’s Encrypt offers free, trusted certificates. pfSense includes plugins and options to easily obtain and install these certificates. This option is highly recommended for enhanced security and browser trust.
4.1 Using the Let’s Encrypt Plugin (Recommended)
The simplest way is to install and use the Let’s Encrypt plugin from the pfSense Packages repository. This plugin automates the process of obtaining and renewing certificates. Follow the plugin documentation for guidance. [External link to a tutorial about Let’s Encrypt on pfSense]
4.2 Manual Configuration (Advanced Users)
For advanced users, manual configuration is also possible but requires a deeper understanding of the Let’s Encrypt protocol and pfSense’s configuration.
5. Renewing Your SSL Certificate
SSL certificates have an expiry date. Self-signed certificates have a more flexible time frame, while certificates from CAs (like Let’s Encrypt) usually expire after 90 days. Always ensure that your certificates are renewed before they expire to maintain a consistently secure network. Let’s Encrypt certificates can usually be automated through the provided plugins or tools.
6. Troubleshooting Common Issues
You might encounter some common issues while working with SSL certificates, like incorrect configurations or certificate errors.
6.1 Browser Errors
Browser errors most often occur when attempting to use a self-signed certificate which is not trusted by the browser. If possible, obtain a certificate from a trusted CA.
6.2 Certificate Validation
Incorrect names or configurations during certificate creation can lead to validation errors. This typically requires going back to the pfSense configuration and adjusting the settings.
6.3 Private Key Management
Securely storing the private key is paramount. Compromising the private key can lead to a total security breach.
