Cisco Pix 515 Help

[bill.ray]

I need help with setting up my IP addresses properly. I have the IP for the pix, my DMZ and the only outside IP are the same. I don't want to use NAT's. Can anyone give me clues as to what my addresses should look like through the setup process?

how many ip addresses do you have?

I have x.x.x.1 through x.x.x.254. x.x.x.15 is the IP of my firewall, x.x.x.7 is my DNS and my DMZ. x.x.x.100 through x.x.x.254 are my personnel IP addresses. Everything up to x.x.x.99 are equipment (email, web, etc.). I am trying to figure out how to set up the addresses (inside, outside, dmz). I have looked at several diagrams but still getting confused.
