We have openstack is installed on a bladechassis controller is one blade, network is another blade and so on. But we want the floating IPs firewalled, can I put my firewall in the openstack instance?

Is your question to use the firewall in the instance instead of the security group? If you are using neutron, your security groups are applied on the compute node directly before the Instance, this means that the security group is applied to both the floating IP traffic as well as the private netwo

Hi, thanks for the response.

We want to use private addressing for the floating IPs so they are reachable from our internal network.. but we want to set up a nat as well for when it goes out to the internet. So I was thinking of adding a vyatta firewall in the openstack instance for the nat.

Also you can run a firewall + router software in an instance. I have did in my case between two networks.
