Where are you trying to access your DMZ from? Inside, Outside?

From the outside

Hi. I noticed that you are NATing in to the webserver with global IP 209.165.200.227, but you are NATing out of the DMZ to the interface, with the IP 209.165.200.226. Is that perhaps a typo? Because it looks like you are NATing all outgoing requests from the DMZ to a different IP address than the one you are NATing in on. So quite possibly you are responding to requests from .226. This could be why.

Test by removing the following from your config

object network dmz
nat (dmz,outside) dynamic interface

The probleù was resolved
