Good Day All,

I am new to McAfee products. We have Network Security Manager (Version: 8.3.7.64) , and I'm trying to block specifique IP Address with Firewall Policy to reach an IP address server , the IP is not blocked but when I add this IP adress on the quarantine ,The blocking function Work. How can I make the blocking function of Firewall policy works.

Thanks

Hello,

What does the firewall policy look like? Do you have any other rules being hit prior to this one that might be allowing it? Where do you have the FW Policy applied? Pre/Post/Interface/Device? Can you upload a screenshot of the firewall policy and rule? Feel free to obfuscate anything that isn't relevant.

Regards,

Matthew

I have assigned the FW policy on all interfaces

Hello,

Sorry for this simple question, but Just in case, do you have control over this IP Address? How are sure that the rule is not blocking the traffic?

Can you share with us the Rule Object Settings?

And what is the use case that you are implementing that rule?

Thank You

Lucas

The problem was resolved by looking after the real IP address of the server ( the server was behind a proxy )
