title: how can i accept quickfix acceptor sessions over 2 IPs and ports?
body: <p>This is for internal and external DNS settings. So my config file says:</p>
  
  <pre><code>connectionType=acceptor
  SenderCompID=provider
  TargetCompID=client1
  SocketAcceptAddress=X.X.X.X
  SocketAcceptPort=1901
  </code></pre>
  
  <p>and then</p>
  
  <pre><code>connectionType=acceptor
  SenderCompID=provider
  TargetCompID=client2
  SocketAcceptAddress=url.mapping.to.X.X.X.X
  SocketAcceptPort=1902
  </code></pre>
  
  <p>and the acceptor won't run with error:</p>
  
  <pre><code>quickfix.RuntimeError: java.net.BindException: Cannot assign requested address: bind
  </code></pre>
