# Evaluation order of the translation rules is dependent on the type
# of the translation rules and of the direction of a packet. binat
# rules are always evaluated first. Then either the rdr rules are
# evaluated on an inbound packet or the nat rules on an outbound
# packet. Rules of the same type are evaluated in the same order in
# which they appear in the ruleset. The first matching rule decides
# what action is taken.
