It is essential that both ERA Server and client computers managed by ERA have a working Internet connection so that they can reach the ESET repository and activation servers. If you prefer not to have clients connect directly to the Internet, you can use a proxy server (not the same as Apache HTTP Proxy or ERA Proxy) to facilitate communication with your network and the Internet.

Computers managed by ERA should be connected to the same LAN and/or should be in the same Active Directory domain as your ERA Server. The ERA Server must be visible by client computers. Additionally, client computers must be able to communicate with your ERA Server to use remote deployment and the wake-up call feature.

Ports used

If your network uses a firewall, see our list of possible network communication ports used when ESET Remote Administrator and its components are installed in your infrastructure.
