Controlling ports generated by the server for the clients 'real' connection.

I have an RMI server within a firewall protected network.

I have requested my firewall administrator allow connection through to 
server port 1099, so that my remote clients can connect initially, the 
server then picks a port on which it asks the client to continue the 
conversation, and this is where my problem begins.

This second port is not open on the firewall so further conversation is 
currently blocked.

I have convinced the firewall administrator to open a range of ports 
within which I would like the conversation could continue, however I 
have completely failed to locate a mechanism by which I can control the 
'second' port chosen by the server, to force it to be within my prepared 
range.

My firewall admin will not open all high ports, not even for a single 
client ip address.

Is there a solution anyone can share or am I barking up the wrong tree?
