What client are you using?  From the client can you ping the gateway?  Can you ping the DNS server?  Can you perform an nslookup?  Can you resolve a FQDN from the Internet?  Can you ping an IP on the Internet?

Did you setup NAT for the DMZ subnet?

I meant, when I set "Obtain automatically ip address" on my windows laptop client, it sets also the dns but still not connect to internet!

Do you have an access-list on the DMZ interface?  Can you post a "show run" or at least the following:

show run nat
show run global
show run access-list
show run access-group
