[rdo-list] Access undercloud / overcloud vms via public ip addresses

Hi All, I'm installing Openstack via tripleo-quickstart. Is it possible to assign ip addresses other than the defaults to the undercloud / overcloud vm's such that they are publicly accessible within our networks? I have seen this to configure undercloud.conf: http://ucw-bnemec.rhcloud.com/ But the undercloud vm itself is assigned a 192.168.23.x address so that also needs to be modified somewhere. Regards, Ed
