I've configured PAT on my ASA and it's work but I don't know why that suddenly become not working (I remember it's seem become not working after active DMZ). For troubleshooting, I've tried to configure another PAT command and packet-tracer (below command, output and attched JPG), could any one can help me to check what's wrong with my ASA? thank you so much!!!!!!
Testing Command:
object network TEST_HTTP
host 192.168.0.34
nat(inside,outside) static interface service tcp http http
access-list ACL_TEST_HTTP permit tcy any host 192.168.0.34 eq www
access-group ACL_TEST_HTTP in interface outside
Output of Packet-Tracer

From packet tracer output, ii looks like UN-NAT is not happening,
In case you have any manual NAT for Inside to Outside, try pushing it after object NAT using "after-auto" command in manual NAT statement.
Hope it helps.

Hi risseth,
Thank you so much for your reply, may this beginner ask you a question, how can I do to re-order the manual NAT statement,
Thank you so much!!!! ^_^

config for after-auto would look like this:
***********************************************************
Without after-auto statement:
nat (inside,outside) source dynamic any interface
================================================
above mentioned nat with after-auto parameter in NAT statement:
nat (inside,outside) after-auto source dynamic any interface
hope it helps.
