This is related to http://jira.jboss.com/jira/browse/JBESB-507
There might be a quick fix but I'm not aware of it just yet.
Have you tried starting the ESB Server with a -B 192.168.2.1 trick? You can set up loopback adapters on the local machine and basically tie the various server engines to different IP address without changing the ports. This is recommended for JBoss App Server as well.
I've not tried it but I thought I would throw it out there in case you had a chance to test the technique.
Thanks for pointing to the JIRA. I have faced exactly the same problem mentioned there as I am also using the server-bindings.xml reference in my jboss-service.xml to pick up the configurations of various servers and ports.
For now, I think I will just avoid using ESB until these port issues are resolved.
