SSL Installation: F5 BIG IP (version 9)

The following instructions will guide you through the SSL installation process on F5 Big-IP Load Balancer V9.

If you have more than one server or device, you will need to install the certificate on each server or device you need to secure.

  • Make sure you have all the following files saved before proceeding:

Your Server Certificate
This is the certificate you received from the CA for your domain. You may have been sent this via email. If not, you can download it by visiting your Account Dashboard and clicking on your order.​​​​​​​

Intermediate Certificates
These files allow the devices connecting to your server to identify the issuing CA. There may be more than one of these certificates. If you got your certificate in a ZIP folder, it should also contain the Intermediate certificate(s), which is sometimes referred to as a CA Bundle.

Your Private Key
This file should be on your server, or in your possession if you generated your CSR from a free generator tool. On certain platforms, such as Microsoft IIS, the private key is not immediately visible to you but the server is keeping track of it.

  1. Launch F5 Big-IP Web GUI.
  2. Select SSL Certificates, under Local Traffic.
  3. Select your certificate’s name under General Properties.
  4. Select the yourdomain.crt file that you received from the issuing CA.
  5. Select Open, then Import.
  6. To enable the intermediate certificates, return to the Web GUI, and under Local Traffic, select SSL Certificates.
  7. Choose Import.
  8. In Import Type, choose Certificate and Create New.
  9. Name your Intermediate Certificate.
  10. Find the CA bundle that includes your intermediate, click Open, then Import.
  11. To enable the SSL certificate, create or open an SSL Profile for your Certificate.
  12. Choose Configuration, then select Advanced.
  13. Select the SSL Certificate you just installed.
  14. Under Chain, find the Intermediate Certificate you just imported, then select Save.

Congratulations! You’ve successfully installed your SSL certificate!
