How to add IP to the XDR whitelist without any security analysis

Grady.Chen — Fri, 10 Sep 2021 10:35:20 GMT

My user generated a behavioral threat alert, which caused the two PCs to not be able to communicate with each other. After we turned off the protection function of xdr agent, they were able to communicate with each other. I did not see the block ip on the XDR cloud server. Someone Can you tell me why?

I added allow ip below but it did not take effect

Hi @Grady.Chen,

Like that it is not easy for anybody to provide a proper response to your question, I would recommend opening a case with TAC and provide the logs of the agent for further investigation.

If you look under the response tab, action center. You can see on the left side the Endpoint Blocked IP Addresses. That is where you should remove that IP address to allow communications again. Screenshot is provided below.

Hopefully this cleared up your issue.
