no ping to Instance from neutron-gateway/0 - error "Destination Host Unreachable"
I performed a cluster node installation using this guide [OpenStack Charms Deployment Guide].(https://docs.openstack.org/project-deploy-guide/charm-deployment-guide/latest/install-maas.html), where the type of network is a Flat network and the components used are:
- Maas
- Juju
- Openstack
My lab is composed by following devices:
- 1 IBM System 3540 M4 Maas (500GB HDD - 8GB RAM - 1 Nic)
- 1 IBM System 3540 M4 Juju (500GB HDD - 8GB RAM -1 Nic)
- 4 IBM System 3540 M4 Openstack (500GBx2 HDD - 16GB RAM - 2 Nic)
- 1 Palo Alto Network Firewall
Public Network 10.20.81.0/24 - Private Network 10.0.0.0/24
- Maas: 10.20.81.1
- Juju: 10.20.81.2
- Openstack 10.20.81.21-24
- Gateway 10.20.81.254
- Instance: 10.0.0.9 - 10.20.81.215 (floating)

On my lab, the nodes for Openstack present two eth interface, the first one (eno2) the single external network used as floating IP, then the other one (eno3) for the private network.
I can not reach teh install via SSH or ping
