So, if you have NAT but a grossly misconfigured router, it might not be secure?
Quick question - do you think that "security by obscurity is not security"? And, as a follow-up, when you park your car do you ensure your laptop bag is out of sight, maybe locked away in the boot?
Because here's a mindblowing concept that'll change the way you see the world - you can have a door lock but it won't make you secure. You need to actually fit the lock to some sort of door.
If you have NAT, that doesn't tell you anything about whether the router is secure. All it tells you is that outbound connections made through the router will appear to come from the router's own IP; it doesn't tell you whether inbound connections will work or not.
