Hello, I have deployed Openstack Havana with Devstack (SINGLE-NODE) My laptop (UBUNTU 13.10) gets IP address from wireless router (Gateway; DHCP assigns from

I'm using Neutron and here are some lines from my localrc:

    > HOST IP=
    > FLAT_INTERFACE=wlan0

I ./ and Everything works I have public and private network topology and I can assing floating IP to an instance.

The problem is I can't communicate with any instance from controller node by Floating IP, it says DESTINATION HOST UNREACHABLE. I also can't login to cirros Instance because the password contains ":" and for some reason it does not work to type ":".

It seems that I can ping the router:, although I've specified PUBLIC_NETWORK_GATEWAY= :/

Are you using neutron or nova networking? Are you trying to communicate with your instance using the fixed ip or a floating ip? If you log into the instance console, do you have outbound connectivity? Does the instance have an ip address?

Have you created (or does devstack create) security groups that permit ICMP traffic?

Check this site for hints about where to look further, you may have a firewall somewhere or something else wrong. These seem to be hard to debug.
