Load balancing at layer 4 using multiple IP addresses and a load balancer

Just like in the previous recipe, this one will cover load balancing at layer 4; but from a different angle. We will describe the principles and the idea behind this solution, however we cannot cover any device or model specific configuration steps.

Getting ready

To complete the following steps, you will need to use a virtual or hardware load balancer. The load balancer does not need to have any SSL offloading capabilities. In order for load balancing to work properly, you need to ensure that all Client Access Servers are configured with the same certificate.

How to do it...

Note

Please note that depending on the model and make of the load balancer you are using, the terminology that is used might be different. Nonetheless, the same principles apply.

Execute the following tasks on your load balancer:

1. Create a new Virtual Service/Server (VS).

2. Configure the VS to perform the following:
