I'd like to know that is there a way for the booted instance to send network related data to the neutron server. For example, if i boot an instance and install a Network Intrusion detection system (NIDS) and will it be possible to send the information such as source IP address, source Port to the neutron server in case of an attack or malicious traffic.

The above case is too specific but what i want to know is that is there any way in which the instance can make contact with the neutron server to send some instance related information. Even if there is no implemented API for this it is alright :). I'd just like to know whether such an operation is possible and if so then how would it be done.

Thank you.

You will have to route it back as if it was coming from the external network. Treat it as an external computer and use normal methods to get it to work. Scripted api calls or ssh and iptable commands to neutrons external address.

Neutrons entire job is to get data from the VMs internal network to the external network as isolated as possible, without the guest knowing how abstracted from the external network it really is.

It also presents a potential for a very easy DoS attack if a guest can tell Neutron what to block directly.
