To ensure connection integrity, proxy servers and devices external to your demilitarized zone (DMZ) must not perform any method of SSL decryption on outbound or inbound traffic for the Dell secure remote servers. SSL decryption that is performed on outbound communication causes a loss of connectivity to the backend. SSL decryption includes decryption by your firewall, proxies, web traffic filtering appliances or cloud services, web traffic shaping or load balancing, certificate verification, certificate proxy, or Intrusion Detection Services (IDS).

In case the SSL decryption is enabled on the proxy servers and other devices, ensure that esrs3-core.emc.com and esrs3-coredr.emc.com are added to the SSL decryption exclusion list on the proxy servers and devices.
