How to ensure that McAfee ePo works normally without being blocked by my firewall?

[sanba06c]

Hi there,

We're using McAfee ePolicy Orchestrator and have already deployed ENS to endpoints. However, I noticed that our firewall is blocking some ports from ENS to McAfee ePo server, such as  port 443.

Should I whitelist the IP addr of Mcafee Server or restrict it with specific ports?

Hi @sanba06c,

Thank you for your post. Please look into the below KBA for your kind reference:

Allowing the entire Server or the port completely should both help the ePO function fine, however, we would recommend going granular with the exclusions. I hope the above KBA helps you configure the same.
