Configure Interfaces
When you use zero-touch provisioning or the device manager for initial setup, the following interfaces are preconfigured:
-
Ethernet 1/1—outside, IP address from DHCP, IPv6 autoconfiguration
-
Ethernet 1/2— inside, 192.168.95.1/24
-
Default route—Obtained through DHCP on the outside interface
If you performed additional interface-specific configuration within device manager before registering with the management center, then that configuration is preserved.
The following example configures a routed-mode inside interface with a static address and a routed-mode outside interface using DHCP. It also adds a DMZ interface for an internal web server.
