Use Apache HTTP Proxy to configure a mirror on large networks

To minimize Internet traffic and maximize security on networks where ESET Remote Administrator 6 or later 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 along with ESET Remote Administrator Server (ERA Server) using the all-in-one installer, or as a standalone component if you have already installed ERA Server.

I. Enable the mirror feature on your client workstation

On the client workstation where you want to create a mirror server, open the main program window of your Windows ESET product.
Press F5 on your keyboard to access Advanced setup.
Click Update and expand Profiles → Mirror.

Click Update and expand Mirror.

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

Note 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 this information.
