JMS remote topic question

I have a standalone server that produces and consumes JMS messages on a topic and a remote server that also consumes messages on the topic. Everything is working fine, but on my standalone application I have the outbound socket binding set to 5445 the remote server is listening on port 5645(5445 +200 port offset of the application). I verified nothing is listening on port 5445 using netstat -l | grep 5445. Ports 5645 and 6245 are listening. The outbound socket binding on the remote server is set to 6245 which is the port that the standalone server is listening to(5445+800 port offset). If I specified 5645 in the standalone server configuration file, my perception is that things don't work. So I am puzzled, is there really only one connection working here the one on 6245 or does the connection bound to jms-server-1 somehow know to apply the 200 offset for the other server?
