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

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.

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.
