openstack multi region with internal ip

hello Im using kolla-ansible and for security reasons I use invalid ip for main compute ip . my compute have 2 network adapter and first adapter that is for management is not accessible from outside . the problem is I want to add new region in other datacenter and on openstack with multiregion keystone is deploy only on one region not all regions so my computes with invalid ip can not access keystone anymore . is there any solution for this case ?
