Can't a pix be licensed and support multiple DMZs?
I understand what you are trying to do with 2 FWs, but Dan is right. IMO.
Take a look at the new ASAs. I'll bet you will be more likely to be
approved for redundant Cisco ASAs with all the new security features
built in, before 1 PIX + maint. and 1 VendorX + main. + training +
added complexity.
An ASA is PIX under the hood.
Everyone needs are different though. Good luck.

I have to setup a DMZ on our network. Our current layout is Internet Router
<--> Firewall <--> WAN/LAN Router <--> Servers
The idea is to setup a back-to-back DMZ or Dual Firewall DMZ. So the topology
would be like this..
Internet Router --> FW-1 <--> DMZ <--> FW-2 <--> WAN/LAN router.
On the DMZ we will have a Web Server that needs access back to the Mainframe
on the LAN, and a Mail server that need access to another mail server on the
LAN.
One of my questions is the DMZ is in a /24 subnet and the LAN is on a /16
subnet. Is the only way for the web server in the DMZ to communicate with the
inside LAN by NATting in the FW-2. Isn't this creating a double subnet from
the outside??
I am working with 2 pix firewalls, and I am hoping to change FW-2 to a
different brand that has stateful inspection.
Please Advice,
Thanks,
Pablo

If you spend more on coffee than on IT security, you will be hacked.
What's more, you deserve to be hacked.
