Bug Description
The gateway defined on those settings is set on the management network which is a private network of openstack. I fail to see where this ip have been defined in any of the 3 node to allow external connection. Isn't the gateway supposed to be defined as the network node then wouldn't it be 10.0.0.21 ?
I'm trying to build this exact architecture and the only card that is connected to the external router/gateway is the external one (eth2 on the network node, which is dhcp and get a 192.168.3.14 as ip for eth2 ). Any other node are just connected between themself on different switch and either with the gateway defined as 10.0.0.1 or 10.0.0.21 none can get to the internet. Is there a missing step in the configuration requirements ?

I "think" I figured it out. The explanation are very confusing. The external interface is actually not the one to which you connect from the external. You have to have a router with a static route for the management network.
The configuration of the /etc/network/ interfaces need also to include the setting dns-nameservers 10.0.0.1 otherwise dns is unreachable.
So, if I understood correctly, I'm completely clueless on the utility of the "external" network that is unnumbered now. If from the external you connect to the management network, what is the purpose of the external network. If I understoof incorrectly then correct me.
I'm really under the impression that the network node should be a router of some short to process local traffic and that the only entry point of those network was the external NIC on the network node. But after like 3h of trying to figure out something I came to conclusion that having to build a complete router is not just one missing line of code and thus is probably not the solution.
Keep me posted on that. I'll try continuing installing OpenStack with my new configuration and see where it goes.
