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.

Note: DFL-800/DFL-860 allows either HTTP
or a secure HTTPS connections from any
management host. However, for security reasons,
only a secure HTTPS connection is allowed by
default. For more information about configuring
connections settings, please refer to the Firewall
User Manual.

Table 4. Browser Compatibility
Connect your workstation on the LAN port
labeled 1.
Ensure your workstation is configured with a
static IP address in the 192.168.1.0/24 subnet.
Note: Disable pop-up blocking software
or add the management IP address
https://192.168.1.1 to your pop-up blocker's
allow list.
Launch your browser; enter the IP address for
the LAN1 interface, then press Enter.
(The factory default IP address is
https://192.168.1.1)
