Issue Using RMI Through Devices that Perform NAT

The combination of Java RMI and NAT has an inherent issue, in that Java attempts to route client requests to the IP of the computer on which the RMI server is running, rather than to the masqueraded address supplied by NAT.

To work around this issue, the Java Virtual Machine (JVM) accepts two arguments that allow RMI server programs to communicate with clients using the IP of another computer or device, such as a router that performs NAT.

If your Report Client computers access Reports Server components though a device that masks outgoing packets through NAT (Network Address Translation), then you must follow the procedures listed below.
