As I just found out (Thanks Martin Josefsson!) there is available a
conntrack match. It lets you match more than the three conntrack states
you mentioned - you can match conntrack status like ASSURED, SEEN_REPLY,
etc, as well as 'states' SNAT and DNAT (matches packets which have been
SNATted or DNATted) and also match the original pre-SNAT/pre-DNAT IPs.
