Instances can't get IP from the neutron DHCP server in OPENSTACK

admin

I have openstack wallaby running in two vm in VBox with Ubuntu 20.04, Controller and compute1. Everything runs without issues in provider network flat type except the dhcp. For example, I have a network created in the range of 192.168.8.20-192.168.8.30. I selected to have a DHCP. The instance gets an ip and runs, but when running it I can't get a response from the DHCP, like it did not exist. I mean, the port is attached to the DCHP with the ip 192.168.8.20. I can even connect to it running ip netns.

% _0 D; _0 C# k) P8 g% o( SWhen i try to ping the instance ip from the DHCP to the instance using netns the dhcp server did not get any response from the instance or any device in the network. The network works, because if I setup the ip manually in the instance I can get access to the gateway. But it didn't see the DHCP server, sending DHCP_DISCOVER without any response.
