Nova-network with external gateway

I need to setup a shared hosting environment. Everything is working fine except the networking. I've created a network with the following command:

nova network-create testnetwork --bridge br100 --multi-host T --fixed-range-v4 --gateway --dns1 --dns2

The result should be that we are using our external gateway in the datacenter. The gateway has many ips and one of them is The complete network except the first ip should be useable on every node host. To reach the instance is not the problem but the instance has no outgoing network connection.

I've seen that one of the node servers got the ip address I don't want to use the node server as gateway. Is there a possibility to use the external gateway? The instance is already in the same network bridge like main interface p4p1.

Would be very awesome if anyone has a idea.

//EDIT: Or is it better to use neutron networking? But I have a very bad feeling about that the complete network traffic runs over one server (ddos).

Best regards, Alexander

I've using now Neutron with Linux Bridge and a Provider Network. It's perfect for our use-case.
