Hi,
I hope I have understood what you wrote and created the following query
correctly:
select uip.vm_id, uip.network_id, uip.public_ip_address,
n.state as nic_state, n.removed as nic_removed,
vm.state as vm_state, vm.removed as vm_removed
from user_ip_address uip
join nics n on uip.vm_id = n.instance_id
join vm_instance vm on uip.vm_id = vm.id
where uip.id in (Select ip_address_id from firewall_rules fr where
fr.network_id=205);
+-------+------------+-------------------+--------------+---------------------+-----------+------------+
| vm_id | network_id | public_ip_address | nic_state | nic_removed |
vm_state | vm_removed |

Is VM id 15 what you are looking for?
Thank you
