Step 3 If you want internal clients to use DHCP to obtain an IP address from the device, choose Device > System
Settings > DHCP Server, then select the DHCP Servers tab.
There is already a DHCP server configured for the inside interface, but you can edit the address pool or even
delete it. If you configured other inside interfaces, it is very typical to set up a DHCP server on those interfaces.
Click + to configure the server and address pool for each inside interface.
You can also fine-tune the WINS and DNS list supplied to clients on the Configuration tab. The following
example shows how to set up a DHCP server on the inside2 interface with the address pool
192.168.4.50-192.168.4.240.

Step 4
Choose Device, then click View Configuration (or Create First Static Route) in the Routing group and
configure a default route.
The default route normally points to the upstream or ISP router that resides off the outside interface. A default
IPv4 route is for any-ipv4 (0.0.0.0/0), whereas a default IPv6 route is for any-ipv6 (::0/0). Create routes for
each IP version you use. If you use DHCP to obtain an address for the outside interface, you might already
have the default routes that you need.
Note
The routes you define on this page are for the data interfaces only. They do not impact the
management interface. Set the management gateway on Device > System Settings > Management
Interface.
Configure the Device in Firepower Device Manager
