    # Ansible roles can install a multitude of firewall rules, some of which
    # will lock us out of our Molecule test VM if we don't take precautions.
    # As Molecule itself uses SSH just like Ansible, we need to open port
    # tcp/22 to the private /24 subnet that Vagrant uses when provisioning the
    # VM. As we don't know for sure what the address for this subnet is and it
    # can change across servers/platforms, we gather this information
    # dynamically and filter it through `ipaddr` to get the address of the
    # whole subnet. The rule is inserted right on top of the list to make sure
    # we always get access.
