When FortiWeb is deployed upstream of a device performing source network address translation (SNAT) or load balancing, the original client IP address may be lost. To preserve the original client IP address, you must enable and configure the Preserve Client IP setting on FortiWeb. This allows FortiWeb to retain and pass the client's original IP address to the backend servers for accurate logging and processing.

In FortiWeb's API protection mechanisms, there are distinctions between the traditional API gateway protection schema and the machine learning (ML) based API protection schema:​

Data Type Support: The API gateway protection schema has the capability to support various data types beyond just strings, allowing for more comprehensive validation and enforcement of API schemas. ​

Schema Adaptability: The ML-based API protection schema is designed to automatically learn and adapt to changes in the API structure without requiring manual intervention from administrators. This dynamic learning process enables FortiWeb to identify and protect against anomalies and potential threats in real-time.

A self-signed certificate is useful when all the devices in your network can be configured to trust it. In this case, if your enterprise's computers trust the internal Active Directory or Certificate Authority (CA) server that signed the certificate, the self-signed certificate can be used internally for HTTPS connections without raising trust issues.
