- And finally, the "--networking kopeio-vxlan" argument. With the private networking model, we need to tell kops which networking subsystem to use.

**NOTE**: You can add the "--bastion" argument here if you are not using "gossip dns" and create the bastion from start, but if you are using "gossip-dns" this will make this cluster to fail (this is a bug we are correcting now). For the moment don't use "--bastion" when using gossip DNS. We'll show you how to get around this by first creating the private cluster, then creation the bastion instance group once the cluster is running. **NOTE**: You can add the "--bastion" argument here if you are not using "gossip dns" and create the bastion from start, but if you are using "gossip-dns" this will make this cluster to fail (this is a bug we are correcting now).
