Firewall - "Matched Rule: GTI Rule - In"

Jump to solution

 

Our Firewall settings for "McAfee GTI Network Reputation" are set to "Do not block" for "Incoming network-reputation threshold".

But we are seeing "Message: Blocked Incoming ..." with "Matched Rule: GTI Rule - In" in the FirewallEventMonitor.log file.

 

Any idea what could be causing this?

Hi @ezim 

May I ask which version of ENS you are using? We've made some changes to this in the latest update. If you aren't already using the October Update, I would ask you to test it.

The issue is that network traffic can incorrectly be processed by the Firewall GTI IN functionality.  You can workaround the issue by creating FW Options rules (Defined Networks or Trusted Applications; ref KB90837) to allow the network prior to being subjected to the GTI rating system.

Hi there,

We are using ENS 10.6.1 July update.

I've read that there are still a number of issues with the October update, so I'd not be testing it on our live system yet.

I should be able to try in our test environment.

Do you have any further details re the issue?

Thank you for your help

Hi @ezim There was one specific fix  (see below) to the ENS Firewall GTI IN feature that might be related here.  If possible, please do apply the October Update to a test system that reproduces the issue and see if it resolves it.

Ref https://docs.mcafee.com/bundle/endpoint-security-v10-6-1-release-notes/resource/endpoint-security-v1...

Feature Fix
ENSW-25781
Direct-access traffic is no longer blocked by McAfee Endpoint Security
Firewall, after upgrading from Endpoint Security 10.5.4 to 10.6.1.

Hello there,

We are not "upgrading from Endpoint Security 10.5.4 to 10.6.1". Is this still relevant for us then on "fresh" "ENS 10.6.1 July update" installs?

Yes, it's still relevant. The naming comes from how one escalation was titled.

Could you give us some more information about this issue?

Also, is there a workaround available on machines we cannot update with the October update yet?
