title: Client proxy makes Duplex TCP connection. Can only make 5 proxy client instances
body: <p>I have a working server-client setup with clients instantiated using a proxy. The server exposes endpoint using <code>netTcpBinding</code>. The binding's <code>maxConnections</code> is not configured and therefore I understand that the default value is 10. I'm not able to make more than 5 client instances.</p>
  
  <p><strong>My question</strong>.... Because it is a duplex connection, am I right to understand that all 10 connections are taken up by the 5 clients? So the right way to word this would be 10 channels and 5 connections in each direction? I'm not able to get conclusive documentation of this online.</p>
