CSS11500 : Service Problem


We are having a problem for one service on css 11503. We have configured one service with a minimun paramers like port number , keepalive tcp , ip address , port ( 9530). But problem is that application which listens to this port 9530 replies by different port that is 9531. Due to this we are not able to load balance between two servers on 9530 port. Is there any way to overcome this problem. so than when servers replies to this address / port combination CSS will accept these replies and will send it back to client.

any configuration example on is highly appreciable !!

Please see the attached ms-word document.

Thanx in advance



Re: CSS11500 : Service Problem

I am not totally straight on what you are describing - is this a UDP based application?

If TCP this at least superficially is strange behaviour.

If UDP, do you mean host sends to server on dest port 9530, and then the server sends a datagram to the client with a dest port of 9531?

Or do you mean the client opens a TCP connection to place a request on the server, and then closes the TCP connection, and the server then opens a connection with the response?

In both cases is the problem that this response is from the real address of the server?

What I think you need is a source group -
