title: docker: fails to make available 2 process (one on host, one in container, with the same number) on the same host on different IP
body: <p>I run docker container, do port mapping using the -p 192.168.202.148:9999:9999. But docker will prevent container: listen tcp 192.168.202.148:9999: bind: address already in used. On the host machine is running another process on port 9999.
  I thought it might need to raise a virtual en on the interface, and did it. But the error still persists.
  Later, I found a question <a href="https://stackoverflow.com/questions/25036895/how-to-expose-docker-containers-ip-and-port-to-outside-docker-host-without-port">How to expose docker container&#39;s ip and port to outside docker host without port mapping?</a>, did exactly as written in the article, but the result is the same.
  Please tell me, is it possible that on the host machine (192.168.202.146) working process (9999), and also worked in the container process 9999, but it would be available through the virtual IP 192.168.202.148?</p>
