One should do it.... for three NIC's

                --------
               |firewall|-->>-- 192.168.1.0 network -->>-- Internal
               |    /   |
Internet -->>--|  mail  |-->>-- 192.168.2.0 network -->>-- DMZ
               |        |
                --------

Your web/dns server(s) can be in the DMZ net and rest of your machines 
in the Internal net which means the only static IP is for the Internet 
connection.
