Here is the configuration for inside to access dmz:
object network obj-192.168.1.0
subnet 192.168.1.0 255.255.255.0
object network obj-192.168.2.0
subnet 192.168.2.0 255.255.255.0
nat (inside,dmz) source static obj-192.168.1.0 obj-192.168.1.0 destination static obj-192.168.2.0 obj-192.168.2.0
For inside to access the Internet (outside):
object network obj-inside
subnet 192.168.1.0 255.255.255.0
nat (inside,outside) dynamic interface
After the above changes, then "clear xlate".
Hope that helps.
