Using Interoperability clients via the COM connector or using XML system API with firewall in place.  The JDENet communication between the interoperability client and the JDENet listener, on the Enterprise Server, is not reliable as far as knowing which exact TCP ports will be used for communications back and forth, and does not stay on the same port as the original listening port.  When the Interoperability client connects to Enterprise Server, a new port is sent back, designating the real port which will be used for the actual transaction, and this port can be a random port available on the machine.  This poses a problem for knowing in advance which ports to open up through a firewall if the client is outside of the firewall.
