Well, the makers of the PIX were aptly named Network Translations, Inc. The
product is inherently a NAT box...
So it is kind of unfair to say you can't turn off NAT on a PIX but, you can't
:-) You can masquerade it, but it will still create a XLATE entry. It will
rewrite the headers and re calculate the checksum but of course, it will come
out the same. NAT 0 does not turn off nat, it just translates to the same IP
address. I believe the ports are still scrambled for TCP.
No answers here but a related question.....
Why would you not use NAT with a PIX? Are all addresses on the inside and DMZ visible to the world? I take it if they are visible that the inside is still a higher security and the world cannot access the inside except with a static/conduit or ACL?

c outside:aaa.bbb.ccc.ddd/53 dst servers:xxx.yyy.29.80/53but only for this 1 DNS server. The other 2 are working fine.What exactly %PIX-3-305005 means? And why I see it despite wide open NAT 0?Thanks,Przemek
