FortiWeb is blocking groups of users behind your load balancer.

When FortiWeb is deployed behind a load balancer or upstream proxy, it may see only the load balancer IP address as the source for every request. This causes poor client identification and can lead FortiWeb to block many legitimate users as if they are one abusive client. The correct fix is to preserve the original client IP address in an HTTP header, commonly using X-Forwarded-For or a similar trusted client-IP header. FortiWeb can then be configured to read that header for accurate client identification, logging, rate limiting, and IP-based security decisions. Bot detection, signature updates, and HTTPS caching do not solve the core source-IP visibility problem.
