Firewalls and proxy servers

Some functions of Lenovo XClarity Administrator, including management server updates, firmware updates, service and support, require access to the Internet. If you have firewalls in your network, configure the firewalls to enable XClarity Administrator management server to perform these operations. If the management server does not have direct access to the Internet, configure XClarity Administrator to use a proxy server.

Proxy server

If the management server does not have direct access to the Internet, ensure that the management server is configured to use an HTTP proxy server (see Configuring network access).

  • Ensure that the proxy server is set up to use basic authentication.

  • Ensure that the proxy server is set up as a non-terminating proxy.

  • Ensure that the proxy server is set up as a forwarding proxy.

  • Ensure that load balancers are configured to keep sessions with one proxy server and not switch between them.
