I have a FTD 1150 running v7.2 and managed by the FMCv. After the upgrade, I found the "SaaS" SNMPv3 monitoring can not reach internal devices through the FTD. From the packet tracer, it shows the traffic is "blacklisted by the SSL preprocessor"...Screenshot below.

I do have "SSL preprocessing" enabled and "Stop inspecting encrypted traffic" checked within my NAP for SSL preprocessor.
But there is no event log captured for the traffic for some reason. I also tried to do "system support firewall-engine-debug" but FTD showed me nothing...
Hope this is not another bug in v7.2 but the system works just fine with v7.0.1.1...
Suggestions?
