Hello,
Exactly... Good to know it is working now.
Do you know why it needs the IP address ( as a transparent firewall)???
The ASA will act as a layer 2 device right, transparent to the network but what happens when the ASA does not know about a particular destination mac-address.. What would be the source ip address of that packet??? The ASA's Ip address. So that is the main reason why we need that.
We also use it for managment traffic to the box and for AAA services ( if authentication is used the ASA will send the AAA authentication request to the server) with this source IP address.
Please mark the question as answered, so future users can learn from this

solved
ciscoasa(config)# ip address 192.168.175.1 255.255.255.0
without ip address configured it dosnt work
now it works
ciscoasa# sh access-list
