[KB6792] Configure an ESET endpoint product to function as a Mirror server (7.x)


  • Configure ESET Endpoint Antivirus (EEA), ESET Endpoint Security (EES), or ESET File Security for Microsoft Windows Server (EFSW) to function as a mirror server


Use Apache HTTP Proxy to configure a mirror on large networks

To minimize Internet traffic and maximize security on networks where ESET Security Management Center 7 is used to manage a large number of clients, we recommend that you use Apache HTTP Proxy, rather than configure a client as a mirror. Apache HTTP Proxy can be installed with ESET Security Management Center Server (ESMC Server) using the all-in-one installer, or as a standalone component if you have already installed the ERA Server.

Differences between Apache HTTP Proxy, Mirror Tool and direct connectivity

Each solution has a different effectivity based on number of client machines. For detailed information, see our ESMC Online Help page.

I. Enable the mirror feature on your client workstation

  1. On the client workstation where you are creating a mirror server, open the main program window of your ESET Windows product.
  2. Press the F5 key to open Advanced Setup.
  3. Click Update and expand Profiles Update Mirror.

  4. Click the slider bar next to Create update mirror to enable it. We recommend that you also set a Username and Password for clients to access the update mirror. Click OK when you are finished.

  1. Copy the IP address or fully qualified domain name (FQDN) of the client computer where you created the update mirror. You will use this information to configure policy settings so that other clients will download updates from this mirror. Proceed to part II when you have copied this information.
