You will also need to configure the Java ORB to use localhost.

By default, both Java and omniORB will:
     1. listen for network connections on *all* network interfaces
     2. publish object references (IORs) using the hostname obtained
        from the operating system

You have reconfigured omniORB to use only localhost for both of the
above by using the "endPoint" option.

I'm not sure how to reconfigure the Java ORB to listen only on
localhost, but I know that you can adjust the hostname published in IORs
from the Java ORB by using the java property called
"com.sun.CORBA.ORBServerHost":

   java -Dcom.sun.CORBA.ORBServerHost=127.0.0.1 ...

If this is not sufficient to keep your firewall software happy, then you
might like to try out another Java ORB such as JacORB which may be more configurable:
