How to get IP of client when request is proxied via HTTP Gateway ?

Issue

• We use this code to get the client ip in the jax-ws service.

        Message message = PhaseInterceptorChain.getCurrentMessage();
        HttpServletRequest request = (HttpServletRequest)message.get(AbstractHTTPDestination.HTTP_REQUEST);
        String remoteAddr = request.getRemoteAddr();
        // Handle proxy
        String header = request.getHeader( "x-forwarded-for" );
        if( header != null && !header.isEmpty() ) {
            remoteAddr = header.split( "," )[0];
        }

• This works when we make the request the CXF endpoint in Fuse.
• But when the request is proxied through the http gateway - we get the ip address of the Gateway server.
• We need to get the ip address when request go through the Http gateway. Recommend a solution.
