Instead of configuring NAT (usually referred to as "port forwarding"), with IPv6 you only need to worry about configuring your firewall to allow certain connections and block everything else. At the end of the day you have a router that acts as a firewall. Whether the devices are globally routable/reachable (IPv6) or not (IPv4) shouldn't make a difference. IPv6 hasn't reached me either, but I would expect a sane default configuration in consumer-grade routers to block external connections by default.
