PIX was designed from the beginning as a NAT gateway, but you can disable
the use of NAT for your internal address ranges with the 'nat 0' command.

Here's a link that shows an example using 'nat 0':

Every sample configuration on PIX I see involves NAT with public addresses
on the outside interface and private on the inside.  What if you do not want
to use NAT?  Meaning desktop PCs have global IP addresses.  So both inside,
dmz, and outside interface will have valid global ip addresses, like a class
B address subnetted.  Will PIX support that or was it designed for NAT?

I am trying to understand PIX.  I don't have access to a PIX.

Van
