When FortiGate performs SSL/SSH full inspection and detects an invalid certificate, there are three valid actions it can take:

Allow & Warning: This action allows the session but generates a warning.

Block & Warning: This action blocks the session and generates a warning.

Block: This action blocks the session without generating a warning.

Actions such as "Trust & Allow" or just "Allow" without additional configurations are not applicable in the context of handling invalid certificates.

In the security profile, there are application overrides for specific Facebook-related features, such as "Facebook" and "Facebook_Video.Play." However, the absence of specific signatures for actions like "Facebook_Like.Button" might be preventing reactions. You need to ensure that the necessary application signatures for all desired Facebook features, including reactions (like buttons), are included in the security policy. Therefore, retrieving or adding those signatures would resolve the issue.

To block access specifically to download.com while allowing other sites in the "Freeware and Software Downloads" category, you can create a separate firewall policy with a deny action specifically for the FQDN *.download.com. This approach allows blocking this particular site without affecting the other sites in the same category. Alternatively, configuring a static URL filter entry with the type set to Wildcard and action set to Block will also achieve the desired effect by directly blocking the specific URL without impacting other sites in the category.
