esaReflectorIpAddress is a read-create IpAddress specifying the IP address the ESA Reflector listens on for incoming test packets. An administrator sets this to the actual address of the remote endpoint whose service is being monitored, since the reflector only responds to packets destined for this configured address. For example, entering the wrong IP address here would leave the reflector silently deaf to the probe's test packets, causing every associated probe to report total packet loss even though the network itself is fine.
