- It would be an extremely useful feature to be able to sample and log NAT/PAT translations used by virtual routers in Neutron.
A couple of days ago we had an attack against one of the IP addresses that belong to a virtual router inside a tenant in our production OpenStack deployment. It was very hard to track down the actual virtual machine being attacked as the virtual router is performing NAT/PAT, hiding the actual private IP address of the victim.
It would have helped considerably if Neutron could keep a history of NAT/PAT translations as well as current ones.
