I have a standalone java client accessing a CORBA Server which is running behind a firewall. This firewall uses Network Address Translation (NAT).

The server sends its internal address to client and because of that my client is not able to access CORBA Server from outside network.

I have spent days solving this problem. Any help is appreciated.

You don't mention what the server is running. Here is an example config for omniORB, there should be a similar functionality for your implementation. Otherwise there is commercial software available also:

The I-DBC concentrates all incoming IIOP traffic on exactly one transport address (1 IP address, 1 port). In order to make Corba/EJB and NAT play together, it automatically and transparently adapts Corba/EJB object references (IORs) to NAT translated addresses.
