Comment 5 for bug 1523709

Alex, looks like you are re-using already created environment (with option '-k' ), so the test is not re-created networks.

According to your XMLs from networks, admin and public networks were created in 'route' mode instead of 'nat' mode.

Please check environment variables ADMIN_FORWARD, PUBLIC_FORWARD and FORWARD_DEFAULT.

Here you can find defaults: https://github.com/openstack/fuel-devops/blob/master/devops/settings.py#L129-L131

Moving to invalid until more details provided.

The bug wasn't reproduced on my local workstation:
