Note: If you have an inside router instead of a switch, you can skip this section and instead configure the ASA to route between
management and an inside network. In this case, configure the ASA and the ASA FirePOWER Management 0/0 IP addresses to be
on the same network. Be sure to configure appropriate routes on the ASA and on the ASA FirePOWER so the management network
can reach the inside network, and vice versa.
This procedure lets you connect to the ASA console port and paste in a new configuration that configures the following behavior:

inside --> outside traffic flow

outside IP address from DHCP

DHCP for clients on inside

Management 0/0 belongs to the ASA FirePOWER module. The interface is Up, but otherwise unconfigured on the ASA. The
ASA FirePOWER 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 module
configuration. You should consider this interface as completely separate from the ASA in terms of routing.

ASDM access on the inside interface
To achieve the above configuration, perform the following steps.
