The settings.yml file references a network settings file with the `network_profile` option. This file has configurations that are related to the network.  The source code for the starter template file is at [network/default.yml.tt](https://github.com/tongueroo/ufo/blob/master/lib/template/.ufo/settings/network/default.yml.tt)  Here's an example network settings file.

  - subnet-33333333

# Optional existing security group ids to add in addition to the ones created by ufo.
# elb_security_groups:
