Re: transparent mode Firewall with 4 ports transparent mode Fire
Accoding to the ASA manual:
Note Transparent firewall mode allows only two interfaces to pass through traffic; however, on the The ASA 5510 and higher adaptive security appliance, you can use the Management 0/0 interface (either the physical interface or a subinterface) as a third interface for management traffic. The mode is not configurable in this case and must always be management-only.
Also if you desire yopu can configure your device in multiple context mode and use all 4 interfaces. 2 for each context.
