Client cannot access CORBA Server behind firwall

[s Joshi]

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.

What CORBA provider are you using?

Look for something like "proxy" in the documentation - the "proxy" is the address you want the client to use.

I am using Sun's CORBA provider.

I am looking for an open source proxy server. Any recommendations?

You mean the version of CORBA that comes with the JDK?

You might be able to use the "org.omg.CORBA.ORBInitialHost" property in your clients - look in the JDK tool docs for more information.

As far as a good open source CORBA implementation - JACORB is an open source Java implementation.

hi mate. specify OAIPort number and OAIAddr in your jacorb properties

file, or pass the property in your code,

e.g. OAIport = 3000
OAIAddr = 192.168.10.10

you servant on 92.168.10.10 will create a tcp server port on local port 3000 at address 192.168.10.10

so those information need to be set on firewall e.g. inbound and outbond on port 300 should be open
