** Description changed:

  I've installed Openstack Juno (fresh install, two weeks ago).
  
- The ping from any network to instances works, but I have an issue with SSH (from any host). 
- I tried with and without SSH keys, and that's the same problem.  
- I tried with Cirros and Ubuntu14.04 instances.

  I've installed Openstack Juno (fresh install, two weeks ago).

  The ping from any network to instances works, but I have an issue with SSH (from any host).

  I tried with Cirros and Ubuntu14.04 instances.
