title: X11 forward display from docker container to a non-host display
body: <p>Host A - Remote Linux server ( No GUI )
  Host B - Remote Windows ( GUI )
  Host C - Remote Windows ( GUI )</p>
  
  <p>Scenario: Using Putty on Host B and XMing and setting X11 forwarding to <code>:0.0</code> and ssh to Host A; next, open any visual editor -> UI successfully displays on Host B.</p>
  
  <p>Running a docker container with X11 forwarding also sends the display to Host B when supplying the env DISPLAY=Host-B-IP and /tmp/.X11-unix volume.</p>
  
  <p>Now, on Host C with XMing, ssh via putty similarly to Host A and open a visual editor; this displays on Host C as expected. </p>
  
  <p><strong>The problem part:</strong> I'd like to run a docker container from Host A to use the display of Host C (which fails/timesout).</p>
  
  <p>Note: Whether I run the container when connecting from either Host B or C doesn't display despite setting the docker env DISPLAY to Host-C-IP. However, if use the IP of Host B, it displays on B successfully in both cases.</p>
