##########
# Network ACLs enforce the basic rules of the topology, and are
# further refined by security groups on instances.
#
# Topology has two "public" subnets (in different AZs) for 
# servers such as searchheads and HECs that are accessible publicly.
#
# It was two "private" subnets (in different AZs) for
# servers such as indexers that aren't publicly available.
#
# The two AZ's can talk to each other.
# The public subnets can be accessed by any service/source
#   allowed by the security group.
# The private subnets are only accessible by the public
#   subnets, and port 22 from anywhere.
#
# Network ACLs allow all outbound. This should be restricted
# via security groups to only those ports needed.
