CDR Testing

Dpj · October 10

Hello, my first post in this section… We want to setup CDR for customers, but first want to get familiar with it, and find out how we configure it, it does what we want.

Is there a method to test it?

Like download some (innocent) files but files what triggers CDR?

I know Microsoft has some test files, but do they trigger CDR?

Home - Microsoft Defender Testground (i hope this isn't triggered as spam….) just an example from them

Yours dennis

Hello Kay,

we use currently the USG Flex 200 with UTM License. We are testing if this license is usefull for our customers. Beside how to configure it, we also want to investigate if it does what we want it has to do.

Hi @Dpj

You can refer to the article mentioned earlier and try configuring CDR on your USG FLEX 200 to see if it meets your requirements.

Hi,
What is the port used to display the message on client browsers in case of CDR blocking?
I have already had blocks with CDR but users do not have a message, only a loss of network resources.
(It must be blocked by a policy rule…)
Thanks

If you have confirmed that everything is set up properly, please share the destination you are accessing, your firewall management mode (on-premises/Nebula), and a screenshot of the relevant event logs.

If you're using Nebula cloud mode, please enable Zyxel support access and provide your Nebula organization and site name.
