Basic Device Configuration
Default Route
The default route is a static route used to direct packets addressed to networks that
are not explicitly listed in the routing table. If a packet arrives at the device with an
address that the device does not have routing information for, the device sends the
packet to the destination specified by the default route.
WebUI

OK :

Management Interface Address
The Trust interface has the default IP address 192.168.1.1/24 and is configured for
management services. If you connect the 0/2—0/4 port on the device to a
workstation, you can configure the device from a workstation in the 192.168.1.1/24
subnetwork using a management service such as Telnet.
You can change the default IP address on the trust interface. For example, you
might want to change the interface to match IP addresses that already exist on your
LAN.
Backup Untrust Interface Configuration
The SSG 20 device allows you to configure a backup interface for untrust failover. To
set a backup interface for untrust failover, perform the following steps:
1. Set the backup interface in the Null security zone with the unset interface
interface [ port interface ] CLI command.
2. Bind the backup interface to the same security zone as the primary interface
with the
set interface interface zone zone_name CLI command.
NOTE: The primary and backup interfaces must be in the same security zone. One
primary interface has only one backup interface, and one backup interface has
only one primary interface.
