Initial Configuration - D-Link NetDefend DFL-800 Guide D'installation

Connecting the Device to a Network
This section provides basic information about
physically connecting the firewall to a network.
The example here is using DFL-800 or DFL-860
to connect the necessary cables as shown in
Figure 5.
1. Connect an RJ-45 cable from the port
labeled WAN1 to the external router. The port
WAN1 is pre-allocated to the WAN1 network
segment.
2. Connect an RJ-45 cable from the port labeled
DMZ to a switch in the DMZ network segment.
3. Connect an RJ-45 cable from the LAN port
labeled 1 to a switch in the LAN network
segment.
4. Connect an RS-232 cable from the console
port for CLI (Command Line Interface)
management access.

Initial Configuration

The NetDefendOS software is pre-installed on
the DFL-800/DFL-860 device. When the device
is powered on, it is ready to be configured. While
the device has a default factory configuration
that allows you to initially connect to the device,
you must perform further configuration for your
specific network requirements.
