can not accece from external network to vm

[hosein]

i installed kolla-ansible on ubtunu20.4
my vm has 2 interface:
ens160:10.4.2.27
ens192: without ip

my global.conf file is:
kolla_internal_vip_address: "10.4.2.27"
kolla_external_vip_address: "{{ kolla_internal_vip_address }}"
network_interface: "ens160"
neutron_external_interface: "ens192"
neutron_plugin_agent: "openvswitch"
nova_compute_virt_type: "qemu"

when deploy that, although i config public and private network (with init-runonce) and assign float ip but i can not connect to vm from local host
