ASA 5510- can't go from dmz to outside 2

[impromptu79]

Please help anyone. This is a configuration for my ASA 5510, and this is just for a lab exercise. I can't see why dmz10 cannot go to outside. Here I will paste configuration for ASA and for a SWITCH that I used. I used our local network in the company to be an outside, we use 172.16.xx.xx addresses. I am just a beginner so I am sorry if there are some trivial mistakes

access-list dmz10toinside extended permit udp host 10.10.10.10 host 10.10.10.11 eq domain
access-list dmz10toinside extended permit tcp host 10.10.10.10 host 10.10.10.11 eq www

The ACL above will definitely not allow any communication outbound beyond what you have specified because of the implied deny any as the last entry in the list. Perhaps add the following as the last ACE in your ACL:

access-list dmz10toinside extended permit ip any 172.16.x.x 255.255.x.x

This will permit all IP communication from the DMZ10 to your Outside network. The x.x in the code above are place holders since I don't know if you're using /16 or /24 prefixes.

I hate all Uppercase... I don't want my groups to seem angry at me all the time! =)

I'm afraid I didn't found solution for my problem yet. When I used just one PC to be an outside network on outside interface, everything worked fine. But when I took my company's network to simulate outside network, then I still had the same problems. I cannot go from outside to dmz nor from dmz to outside. If anyone can help me please, I am thankfull in advance. I have in my company's network one L3 switch, and I don't know if I should do something with it too. Does it need some static route for hosts on the outside to go to dmz, I don't know. My new configurations for ASA and SWITCH L2 look like this:

Could be several things depending on the rest of your network, but here is what I wold try. NAT over a DMZ host to an outside address, try to browse to it, issue a show xlate, see if any translations are happening. You can setup a capture on the boxes as weel for further troubleshooting. It also looks like you will only be able to browse out on vlan 10 and not your other dmz networks, modify your NAT 1 statements if you are trying from the other vlans. Also remember clear xlate when modifying translations and rules.....
