OD Server Mgmt through Firewall

System

Hi, does anyone know how to configure it so that I can manage my remote OD servers through a firewall? OD 5.5.1 SP2

On the receiver I have defined the rmiConnectionPorts to be 13024 to 13033 via the deploy.cfg file. The firewall has these ports open. I also have port 9173 open.

It still doesn't appear to work.

Any help would be appreciated.
