Cisco Firepower 1100 User Manual

Configure Interfaces
Enable FTD interfaces, assign them to security zones, and set the IP addresses. Typically, you must configure
at least a minimum of two interfaces to have a system that passes meaningful traffic. Normally, you would
have an outside interface that faces the upstream router or internet, and one or more inside interfaces for your
organization’s networks. Some of these interfaces might be “demilitarized zones” (DMZs), where you place
publically-accessible assets such as your web server.
A typical edge-routing situation is to obtain the outside interface address through DHCP from your ISP, while
you define static addresses on the inside interfaces.
The following example configures a routed mode inside interface with a static address and a routed mode
outside interface using DHCP.
Procedure
