Internet IP address for firmware updates, e-mail alerts, and essential antivirus updates

Hi, we have placed the PR4100 NAS in a secure network, and we are evaluating opening specific outbound internet traffic to enable the following features:

  • Firmware updates
  • Antivirus updates
  • E-mail alerts

We looked into the product manual but did not find the specific IP addresses and port for these services. We cannot allow wide open outbound internet traffic. Does anyone have this information?


Hi @fabiolanza,

Please refer to the article My Cloud OS 5: Port Usage and Assignments:

Hi, what are the WD server IP addresses that need to be allowed in firewall (outbound)? The post you mentioned shows only the service ports but no IP addresses. Just to be clear, I want to know what is the outbound traffic (NAS → internet WD servers) that need to be allowed so that the services I mentioned work. Thanks.
