I have ASA 5520 with 3 interfaces: inside, outside and dmz. I have a router on the outside with lo 0 192.168.252.6, which I cannot ping from the dmz. I do have a static translation dmz, outside. The route is also there in the ASA to reach the lo 0. I checked the syslog and found out that the ASA is thinking that 192.168.252.6 is inside and that is why I could not ping it. I'm new to the ASA appliance. Can anyone help me on how I can make this work ? Thanks so much.
