What is the main difference of ip configuration(both LAN and WAN & DMZ) in Cisco ASA 5505 and later?

Dmz: 192.168.2.0255.255.255.0Inside: 192.168.1.0255.255.255.0Outside: 1.1.1.1 ! Dynamic NAT for both Inside & DMZ to Internetglobal (outside) 100 interfacenat (Dmz) 100192.168.2.0255.255.255.0nat (inside) 100192.168.1.0255.255.255.0! public address to server in DMZstatic (Dmz,outside) 1.1.1.3192.168.2.20 netmask 255.255.255.255 ! public address to server in Inside static (inside,outside) 1.1.1.2192.168.2.30 netmask 255.255.255.255 ! allow webserver to access DB Servers insidestatic (Dmz,inside) 192.168.1.20192.168.2.20 netmask 255.255.255.255 The point is, when I configure the above, Dmz zone to inside does not work!but when I stop  "static (Dmz,Inside)",  all the inside loose the connection to the net, but all other direction work fine
