Install SSL Certificate on SonicWall

Your online interactions are already underway if you have an SSL Certificate bundled with its private key, neatly packed within a PKCS#12 encoded file (.p12 or .pfx). Installing such a certificate is straightforward and precisely designed to lead you through the seamless installation of your SSL Certificate .pfx file.

Before installation, a crucial initial step is creating a Certificate Signing Request (CSR). This preparatory stage paves the way for a smooth SSL Certificate installation.

Whether your SonicWALL appliance comes in various iterations, these comprehensive instructions encompass the installation process, providing the flexibility to adapt based on your specific appliance model.

Let us begin with the steps to help you install your SSL Certificate confidently.

Part II: Installing Your SSL Certificate

Installing an SSL certificate on your SonicWALL VPN SSL appliance ensures encrypted connections. Here’s a step-by-step guide to installing your SSL certificate:

  1. Begin by preparing the necessary files. Locate the SSL Certificate .crt file that DigiCert provided – typically named something like your_domain_com.crt. Rename this file to “server.crt.”
  2. Combine your server.crt file and the server.key file (which you generated during CSR creation) into a single .zip file called “server.zip.” You can easily create this zip file by copying both files into a folder, selecting them, right-clicking, and choosing “Send to > Compressed Folder.”

QUICK NOTE: If you’ve set a password for your server.key file during CSR creation, remember this password, as you’ll need it later.

  1. Access the SonicWALL VPN SSL appliance portal and log in.
  2. Go to the System section and click on Certificates.
  3. Within the Server Certificates section, click on “Import Certificate.”
  4. In the Import Certificate window, browse to find and open the “server.zip” file you created earlier.
  5. Click “Upload” in the Import Certificate window to initiate the upload process.
  6. After successful import, your SSL certificate will appear in the Server Certificates list on the “System” and “Certificates page.

Part III: Configuring and Implementing Changes

Configuring your SSL certificate settings properly is vital for seamless and secure operation. Here’s how to configure and apply changes:

  1. On the “System” and “Certificates page,” locate your SSL certificate in the Server Certificates section.
  2. Click the Configure icon to the right of your SSL certificate with the pending request.
  3. When prompted, enter the password you set for your server.key file during CSR creation.
  4. Click “Submit” to confirm your configuration.

With the configuration in place, you’re ready to implement your changes and activate your SSL certificate:

  1. On the “System” and “Certificates page,” select the SSL certificate you want to activate from the Server Certificates section.
  2. In the upper-right corner of the page, click “Apply” to apply the changes.

Final Step: Restarting Your Device

In some cases, a device restart might be required to ensure all changes take effect:

  1. If you’re not prompted to restart your SonicWALL SSL VPN device, consider restarting it manually.
  2. Navigate to the System section and click on Restart.

These comprehensive steps guarantee the successful installation and activation of your SSL certificate on your SonicWALL VPN SSL appliance. By securing your connections, you’re enhancing your network communication’s overall safety and reliability.

Generating a New SSL Certificate from Your SonicWall Firewall

If you’re operating on the SonicOS 7.X firmware and are looking to generate a new SSL certificate from your SonicWall firewall, follow these steps for a seamless process:

Accessing the Certificate Settings:

Log in to your SonicWall appliance and navigate to “Device,” “Settings,” and ”Certificates.” You’ll find the necessary options to create your new SSL certificate here.

Creating a New Signing Request:

Within the Certificate settings, locate the **New Signing Request** option. Click on it to initiate the process of generating a new SSL certificate.

Filling out the Certificate Signing Request (CSR):

In the prompted window, provide the essential information for your Certificate Signing Request. Ensure to enter the Fully Qualified Domain Name (FQDN) you intend to use for the SSL certificate.

For those considering a wildcard option, such as *.yourdomain.com, remember that this versatile choice covers all subdomains, though it might involve a higher cost.

QUICK NOTE: Opting for a domain wildcard can be cost-effective while ensuring comprehensive subdomain coverage under a single SSL.

Downloading the CSR:

Once you’ve filled out the CSR information, proceed to download it. You can edit this CSR using a text editor; a recommended choice is Notepad ++. This ensures the formatting remains conducive for transferring the CSR to a certificate authority.

Requesting an SSL Certificate from Your Authority:

Now that you have your CSR, contact your chosen certificate authority. Provide them with the CSR text when requested. Remember, when downloading the signed certificate from the authority, select the appropriate server platform – in this case, Apache SSL.
