Installing an SSL certificate on SonicWall

Once the certificate is issued, it needs to be installed on your appliance. First, you need to download your issued SSL certificate. To download your newly issued certificate from your Namecheap account, refer to this step-by-step instructions and rename it to server.crt.

Note: Due to the peculiarity of the server, it is needed to use default file names. The router will identify the file without any issues:

  1. Create a .zip file with two files. Please take the .crt downloaded from the Namecheap Account panel and also, use server.key generated during CSR creation on your SSL-VPN appliance.
    The easiest way to create a zip file is to copy both files into a specific folder, select these files, right-click on them, and then click Send to >> Compressed Folder.

  2. Log into the SonicWALL SSL-VPN appliance portal.

  3. After that, expand the System menu and click Certificates.

  4. Then it is needed to install CA certificates in order to make your website compatible in browsers.

  5. On the System >> Certificates page, in the Additional CA Certificates section, click Import CA Certificate:

    • On the System >> Certificates page, in the Server Certificates section right near your SSL Certificate with the pending request, click the Configure icon.
    • At the next step, specify the password created during CSR generation.
    • Click Submit.
