jconsole connection trouble. Port redirection?

Hello!

I have a strange issue with jconsole and my JMX enabled daemon. It used to work fine until sysadmin in datacenter placed out machine behind a kind of firewall (cisco accesslist or something like that).

After that remote connection between jconsole and server no longer can be established.

Let's say ip of machine is:host_ip_address

Server side code to start the app:

/usr/java/bin/java -server -Xms64m -Xmx512m -Djava.util.logging.config.file=bin/../conf/logging.properties -Duser.timezone=Europe/Amsterdam -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.host=host_ip_address -Dcom.sun.management.jmxremote.port=8184 -Dcom.sun.management.jmxremote.password.file=bin/../conf/jmx.password -Dcom.sun.management.jmxremote.access.file=bin/../conf/jmx.access -Djava.naming.factory.initial=org.jnp.interfaces.NamingContextFactory -Djava.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces -Djava.naming.provider.url=jnp://localhost:1099 -Dsecurity.policy=client.policy -Djava.security.auth.login.config=/usr/local/jboss/client/auth.conf -cp bin/../lib/Daemon.jar:bin/../lib/Cashier-client.jar:bin/../lib/CoreEJB-client.jar:/usr/local/jboss/client/jbossall-client.jar daemon.Main

Sorry for long string. Just wanted to show it asis.

The daemon used to be controllable by jcosole using remote connection tohost_ip_address:8184

And one day control was lost, jconsole tells that "connecction could ont be established"

After some investigation I found out that jconsole starts connecting to 8184. At this step it works. After that jconsole decides to connect tohost_ip_address:49706. Why? I'm amazed.

I will appriciate any ideas how to get out of the problem.

Or probably explanation about that port49706 redirection.

Here is log of jconsole. Sorry it is quite long, but contains everything.
