    The word you are looking for is firewall not NAT.

    NAT does not provide security whatsoever. If the NAT mapped your (internal IP, internal port) to a certain (external IP, external port) and you do not have a firewall enabled, everyone can reach your device by simply connecting to that (external IP, external port).

    I haven’t seen routers that do not come with IPv6 firewalls enabled by default.
