title: Docker host network not working
body: <p>I am really confused about this problem. I have two computer in our internal network. Both computers can ping internal servers.
  Both computers have same docker version. 
  I run simple docker container  with  <code>docker run -it --rm --name cont1 --net=host java:8</code> command on both computers. Then ssh into containers and try to ping internal server. One of the container can ping an internal server but other one can't reach any internal server. </p>
  
  <p>How it can be possible? Do you have any idea about that?</p>
  
  <p>Thank you</p>
