What are you using as a test of the traffic flow?
ASKER
I was trying to ping from the inside interface to the DMZ interface.
ASKER CERTIFIED SOLUTION

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
ASKER
You were correct it was the access-group entry.
Also that was a mistake adding the ip any any to the inside.
Thanks!!!
