How to Install an SSL/TLS Certificate In F5 BIG IP (version 8 and lower)

The following instructions will guide you through the SSL installation process on F5 Big-IP Load Balancer V8 or Earlier. 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. If you still have not generated your certificate and completed the validation process, reference our CSR Generation Instructions and disregard the steps below.

What You’ll Need

1. 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.

2. Your 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. If not, download the appropriate CA Bundle for your certificate.

3. 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.

Installation Instructions

1.Transfer your certificates

The first step is to transfer your Server Certificate and Intermediate Certificate(s) on to the Big-IP device.

2. Rename your server certificate

If your server certificate has any underscores in the name, you will need to replace all underscores with periods.

3. Copy your server certificate

Your server certificate will need to be copied to: /config/bigconfig/ssl.crt/folder

4. Copy your intermediate certificates

Your intermediate certificate(s) will need to be copied to: /config/bigconfig/ssl.crt/folder

5. Restart your proxy

You can restart your proxy by using the following command:

# bigpipe proxy <IP Address>:443 disable
	  # bagpipe proxy :443 enable

Congratulations! You’ve successfully installed your SSL certificate! To check your work, visit the website in your browser at https://yourdomain.tld and view the certificate/site information to see if HTTPS/SSL is working properly. Remember, you may need to restart your server for changes to take effect.

To check your server’s configurations more thoroughly, use our SSL Checker Tool or contact our Customer Experience Department for additional assistance.
