You can't make both omniNames and your server listen on the same port,
but you can force each of them to use a chosen port. That way, your
security team could open two ports. omniNames automatically configures
itself to always listen on port 2809 (unless you tell it otherwise).
To tell your server to listen on a particular port, give it a command
line argument of -ORBendPoint:giop:tcp::12345, replacing 12345 with
your chosen port number.

Do not put an endPoint parameter in the omniORB configuration file,
because that will mean all omniORB servers try to use the same port,
and therefore all but the first will fail.
