No, the MQPerf probe does not communicate outside the tested host.
Actually the probe runs in a standalone mode. You may execute it on a host without Internet access. However an active network interface is required, as the probe deploys both a JORAM server and a JMS client communicating through TCP.
The popup window appears when a Java program needs to access to the network interface for the first time on this host.
