Do you use CDN? Do you have any other proxy connecting Radware and your Origin?
It is possible you need to configure the XFF in a specific way so your origin server will know the true client IP address, rather than the IP address of the transaction that was received from Radware cloud service.
Here is an explanation of all the ways you can configure the XFF in our portal.
You can also explore the options Radware has for true client IP in our user guide.
