Java APIs

I have been searching for a solution for this issue with all that google knows......


I have my client behind NAT with ip 192.168.27.1

And the server behind NAT with some ip (i am not really worried abt this)

Now I register a client object to server for notification. SImply a hash table in server stores all my client objects. On a expected change, I invoke a method in my client objects.

In this scenario I happened to observer that the client objects sent to server had the client ip (192.168.27.1) inside it and not the NAT ip through which they went out.

So when I went invoke the remote method nothing interestingly happens as the client cannot be located.

I tried creating custom sockets in client and binding it to NAT ip --> obvious bind exception for a ip that is not with client

Setting the NAT ip as java.rmi.hostname in client --> no effect, since still the server is trying to notify (192.16827.1)

Help me to root out this issue. I feel that there must be a solution for this, otherwise RMI it would not have been this much successful.
