I'm using openstack mitaka, I have the controller and the networking (neutron) on the same host and this host is connected to internet via my wifi card (Wlan0), My internal networking is and my default gateway is the "", I have created an internal subnet for the instances (, The instances can ping each other but how can i do to make them connecting to internet ?

You need to provide more information, as there are a zillion ways to configure networking. Did you read the networking guide? How did you set up Neutron? Assuming ML2, what mechanism and type drivers are you using? How is/are the instance network(s) connected to the outside world?

I followed the instruction on the official documentation, for the networking there are two options Provider networks and Self-service networks, http://docs.openstack.org/mitaka/install-guide-ubuntu/neutron-controller-install.html (http://docs.openstack.org/mitaka/inst...) (http://docs.openstack.org/mitaka/inst...) I used the second option,

and the majority of tutorial on the internet and the official documentation is treating the case of a public pool and a private one, but on my case i'm trying to connect the private subnets of instance ( to my physical router (192.168.1).

I think a provider network would be the better or even the only solution. Or your instances are on a selfservice network connected like this:

Instance->selfservice NW->Neutron router->external network->physical router
