block adult images from google images

[leonardomothe]

Firewall version 7.2.9 - 40F

I need to block adult images on Google Images. Could you tell me how to do this?

I have already blocked the category on Webfilter and it still doesn't work.

Setup a proxy-based web filter, and there you can set search engine to safe-search.

Otherwise if you want advanced image filtering then you can do it with FortiProxy.

Is there no other option?

My firewall is configured in flow based mode

I have the DNS filter configured and it still doesn't work.

The flow-based / proxy-based inspection mode is set at firewall policy level and at profile level, not at firewall level. Unless you have very old FortiOS version.
