Firewall rules tend to be complex, which is why mistakes *do* get made and systems still get compromised. NAT interfaces and setups tend to be more simplistic, and the IP addresses of the device won't route publicly through the firewall or any unknown alternate routes.You seem to be arguing that NAT is the only way to prevent inbound access. While it's true that most commercial IPv4 firewalls bundle NAT with packet filtering, the NAT is not required..and less-so with IPv6. -Jack
