D-Link NetDefendOS

NetDefendOS does not allow more than one administrator account to be logged in at the same
time. If one administrator logs in, then a second or more (using different credentials) will be
allowed to login but they will only have audit privileges. In other words, the second or more
administrators who login will only be able to read configurations and will not be able to change
them.
However, NetDefendOS does allow the same administrator account (in other words, using the
same administrator credentials) to be logged in more than once at the same time. This means it
is possible, for example, to have a CLI session in progress as an administrator at the same time as
also performing administrator management operations through the Web Interface.
2.1.4. The Web Interface
NetDefendOS provides an intuitive Web Interface (WebUI) for management of the system via an
Ethernet interface using a standard web browser. This allows the administrator to perform
remote management from anywhere on a private network or the public Internet using a
standard computer without having to install client software.
Note: Recommended web browsers
The recommended browsers to use with the Web Interface are:
• Microsoft Internet Explorer
• Firefox
• Safari
• Chrome
• Opera
Assignment of a Default IP Address
For a new D-Link NetDefend firewall with factory defaults, a default IPv4 address is assigned
automatically by NetDefendOS to the hardware's LAN1 interface (or the LAN interface on
models without multiple LAN interfaces). The IP address assigned to the management interface
is always 192.168.10.1.
Changing the management interface and/or IP address from the default is described in
Section 2.1.2, “Configuring Management Access”.
Setting the Management Workstation IP
The default management Ethernet interface of the firewall and the external workstation
computer's Ethernet interface must be members of the same logical IP network for
communication between them to succeed. Therefore, the connecting Ethernet interface of the
workstation should be assigned the following static IP values:
• IP address: 192.168.10.30
• Subnet mask: 255.255.255.0
• Default gateway: 192.168.10.1
The diagram below illustrates management workstation connection via a switch.
