Configuration

• Firepower 1010—The outside interface, Ethernet1/1, is a

physical firewall interface. All other interfaces are switch

ports that are enabled and part of VLAN1, the inside

interface. You can plug end points or switches into these

ports and obtain addresses from the DHCP server for the

inside interface.

• Firepower 4100/9300—All data inetrfaces are disabled.

• ISA 3000—All data interfaces are enabled and part of the

same bridge group, BVI1. GigabitEthernet1/1 and 1/3 are

outside interfaces, and GigabitEthernet1/2 and 1/4 are inside

interfaces. GigabitEthernet1/1 (outside1) and 1/2 (inside1),

and GigabitEthernet1/3 (outside2) and 1/4 (inside2)

(non-fiber models only) are configured as Hardware Bypass

pairs.

• All other models—The outside and inside interfaces are the

only ones configured and enabled. All other data interfaces

are disabled.

The default outside port based on the device model. See

Configuration Prior to Initial Setup, on page

The IP address is obtained by DHCP and IPv6 autoconfiguration,

or it is a static address as entered (IPv4, IPv6, or both).

Firepower 4100/9300: Data interfaces are not pre-configured.

ISA 3000: None. You must set the BVI1 IP address manually.

If you configure a static IPv4 or IPv6 address for the outside

interface, a static default route is configured for IPv4/IPv6 as

appropriate, pointing to the gateway you defined for that address

type. If you select DHCP, the default route is obtained from the

DHCP server.

Network objects are also created for the gateway and the "any"

address, that is, 0.0.0.0/0 for IPv4, ::/0 for IPv6.

inside_zone, containing the inside interfaces. For the Firepower

4100/9300, you need to add interfaces manually to this security

zone.

outside_zone, containing the outside interfaces. For the Firepower

4100/9300, you need to add interfaces manually to this zone.

(You can edit these zones to add other interfaces, or create your

own zones.)
