Yep… I’ve done a lot of that reeducation over the years. It amazes me the number of people who have trouble separating stateful inspection from NAT and just can’t wrap their heads around the idea that you can still do stateful inspection even if you don’t mutilate the packet header in the process.

I’ve tried as best I can to address it head on each and every time it comes up. I haven’t figured out
a way to be proactive about addressing it that doesn’t come off as antagonistic, patronizing, or confrontational (sometimes I even hit all 3), so suggestions there are welcome.

In fact, I argue that lack of address transparency is contrary to good security because it breaks the continuity of audit trails and makes it harder to identify miscreants and compromised systems.
