Port forwarding is not working in the above version. Please help

Closing since this is not an issue that should be in the issue tracker.
Please see #docker on IRC, forums.docker.com, or the docker-user mailing list for support.

I would also recommend upgrading to the latest version of Docker, 1.8.1.
Thanks!

I am not able to connect 9110 and 8110 port.

Normal port forwarding is working but not working for docker container.
