title: How can I make HAProxy reject TCP connections when all backend servers are down
body: <p>We are using HAProxy to forward incoming TCP connections to a separate server that uses a raw TCP. The issue that we are seeing is that the client connection is accepted and then closed rather then rejected immediately. Since we have enabled a health check is there any way for HAProxy to unbind from the port so that the initial connection fails?</p>
  
  <pre><code>listen custom_forward
     mode tcp
     bind *:11144
     default-server inter 10m fastinter 20s downinter 1m maxconn 100
     server custom_server hostname:10144 check
  </code></pre>
