+    The JMX protocol requires the JMX server (Tomcat in this instance) to listen

+    a firewall. The JMX Remote Lifecycle Listener allows both ports to be fixed,

+    simplifying the process of connecting to JMX through a firewall. See the <a href="config/listeners.html">listeners</a> page for usage instructions.
