## Network configuration
# The AIO bootstrap configures bridges for use with the AIO deployment.
# By default, these bridges are configured to be independent of any physical
# interfaces, and they have their 'bridge_ports' set to 'none'.  However,
# deployers can add a physical interface to 'bridge_ports' to connect the
# bridge to a real physical interface.
#
# A setting of 'none' keeps the bridges as independent from physical
# interfaces (the default).
#
# Setting the value to 'eth1' would mean that the bridge is directly connected
# to the eth1 device.
#
# See https://wiki.debian.org/BridgeNetworkConnections for more details.
