I believe we are talking about the case where some engineer fat-fingers a change and Roger's claim is that a stateful inspection without NAT box will permit unintended traffic while a NAT box will not.
Possibly restating Mark's point, but if fat fingers are allowed as a source of failure, impact is unlimited.
IOW, All of NAT's security comes from the fact that it requires a state table, like stateful inspection.
Er - I think it's a deeper point I was making. To the extent that NAT offers security at all, that security comes as an *unintentional side effect* of the job it is actually designed to do. That is, the NAT device *does not care* about its "security" function. Regards, K.
