Maybe it's easier to prevent this from happening in the first place? Does a second or third copy of a rule have any use to you? As far as I can think this would only make sense in non-terminating rules (like LOG) and rules which match against something internal to netfilter, like -m mark. Maybe you could provide more info on the source and content of the rules?
