I choose provider network option on my OpenStack. I have existing external dhcp server. I need my instance obtain ip address from the external dhcp server. However the assigned IP from neutron mismatch with the ip address of instance from the external dhcp server (different ip address). Then the networking of the instance cannot work properly. Additional, I change the ip address of instance to the assigned IP then its networking work properly,

It is possible to make it work by disabling "port security" under the port you want to optain external dhcp. But it looks "dirty" because of ipp addresses mismatch.
