I have four appliances FortiWeb (6.3.19) working in Standard Active-Active HA and I want to configure Machine Learning as additional security mechanism. Admin guide has one weird limitation "Machine learning is not fully supported when FortiWeb is deployed in active-active HA mode. It doesn't work on the secondary node; On the primary node, it works but not always stable, for example, after system reboot or HA role switch, the machine learning may stop working.". I understand correctly that ML will work only on Master role appliance and traffic that routes via secondary appliances will not analyze?
I didn't find any information about this limitation for v.6.4.2 release. Do you known may be it was fixed there?
