The PIX is late on supporting NAT by seven years or more. All first
generation application layer firewalls did NAT. That goes back to
before the word "firewall"
PIX is perhaps the first *CISCO* firewall to support it.
Raptor has supported using illegal nets since version 2.0, which is
over three years ago. Lest you think I'm touting my product, at the
time, I worked for Milkyway Networks (a competitor), and can tell you
that BlackHole did NAT too, but didn't (and still doesn't) support
illegal nets.
