Hi,

I think the following lines are confusing:-

access-list nonat extended permit ip 192.168.0.0 255.255.255.0 any

access-list nonatDMZ extended permit ip 192.168.100.0 255.255.255.0 any

access-list traffic_for_ips extended permit ip any any

access-list inside_access_all extended permit ip any any

access-list DMZ_access_all extended permit icmp any any

nat (Inside) 0 access-list nonat

nat (DMZ) 0 access-list nonatDMZ

static (Inside,DMZ) 192.168.0.0 192.168.0.0 netmask 255.255.255.0

Can you tell me what are you planning to use this lines for???

to have your inside n/w access DMZ just enter below commands and it will work you dont need any other thing:

access-list inside_nat0 extended permit ip any 192.168.100.0 255.255.255.0

nat(inside) 0 access-list inside_nat0

thts it this will server ur purpose and you will be able to access DMZ frm Inside

and to access DMZ frm Outside you need to create Static\Dynamic Natting as required.
