configuring jconsole support behind firewall

Running tomcat from a firewalled server. Need to use jconsole to force a heap dump (–XX:+HeapDumpOnCtrlBreak is not working in JDK 1.7). I have rights to update iptables.

RMI 'listen' port is open and jconsole can connect, but I understand that the app server will then redirect jconsole to a randomly selected second port - which is firewalled by default.

I've seen various posts on how to get java/tomcat to use a specific secondary port which I could then open through iptables, but I can't get it to work.

Any tipe on how to make tomcat 1.6/jdk 1.7 accessible for jconsole behind firewall?

Apache Tomcat/6.0.32 1.7.0-b147 Oracle Corporation Linux 2.6.18- amd64
I agree. Here's the link:
