Regarding source port configuration

Hello,

What is possible already?
A firewall is setup between the server and the agent.
The agent is preconfigured with its own RMI registry port
(agent_reg_port) and listening port (agent_lis_port).
The server is preconfigured with its own RMI registry port
(ser_reg_port) and listening port (ser_lis_port).
The firewall is configured in this way -
*	Inbound connections to server come only on ser_lis_port
*	Inbound connections to agent come only on agent_lis_port
*	These ports should be opened in the respective directions.
Additionally the two ports - agent_reg_port  and ser_reg_port should
also be opened.
The  RMI registry ports and Listening ports of both Server and Agent can
be configured. This ensures that the server and agent are not reachable
on any other incoming port other than those configured for them.

What is not possible !
In order to reach the server on its specified port, the agent JMX
interface uses an arbitrary source port which cannot be controlled.
In order to reach the agent on its specified port, the server JMX
interface uses an arbitrary source port which cannot be controlled.
The limitation is posed by the JMX interface and not otherwise.
The arbitrary source port is only used by the JMX interface for reaching
the destination port. The response does not come back to the arbitrary
source port, but it goes to the configured listening port of the server
or the agent as the case may be.

So, how can we configure the source port from which the agent/server
connects to a preconfigured port on agent/server in the firewall?

Thanks in advance,
Raghu
