We’d like our Openstack configuration to provide 2 ways to obtain an address on our campus network.
First, I’ve defined an EXTERNAL network and attached a subnet from which floating IP addresses can be allocated. Then, in normal fashion, instance boot into a private tenant network and can be associated with a public IP address or not, as needed. In this case, the proper NAT entries get created allowing instances to reach the metadata service. I’ve also configured a FLAT shared network and associated additional subnets from our campus network. When booting instances and selecting this network for their NIC attachment, the instance comes up directly on a routable address within our campus. However the proper NAT rule is not being added to the iptables which would allow the instances to talk to the metadata service. Assuming a subnet attached to the FLAT network is a /24 subnet with the default router at x.x.x.1 - what’s the iptable rule that needs to be manually added to iptables to allow instances to reach the metadata service. Hopefully this is clear. Additional info can be provided if necessary.
