Firepower Management Center
Note: You must use a separate inside switch in your deployment.
The default configuration enables the above network deployment with the following behavior.

inside --> outside traffic flow

outside IP address from DHCP

DHCP for clients on inside

Management 1/1 belongs to the ASA FirePOWER module. The interface is Up, but otherwise unconfigured
on the ASA. The ASA FirePOWER module can then use this interface to access the ASA inside network and
use the inside interface as the gateway to the Internet.
Note: Do not configure an IP address for this interface in the ASA configuration. Only configure an IP address
in the Firepower configuration. You should consider this interface as completely separate from the ASA in
terms of routing.

ASDM access on the inside interface
Note: If you want to deploy a separate router on the inside network, then you can route between management and
inside. In this case, you can manage both the ASA and ASA FirePOWER module on Management 1/1 with the
appropriate configuration changes.
