# Slots 11-99 are reserved for the traffic that can be accepted based on its
# destination, e.g targeted to / via public interface "outside"
#
# Slots 100-999 are reserved for the traffic that should be filtered
# depending on its target port - this is all traffic that goes through internal
# interfaces. At least you should override 'rule' for slot 100 to specify
# internal interface on which the traffic should be filtered.
#
# These rules should be added / altered somewhere else where it is known what
# interfaces are public / private.
