2.1.3. 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 internal IP address is assigned
automatically by NetDefendOS to the hardware's LAN1 interface (or the LAN interface on models
wihout multiple LAN interfaces). The IP address assigned to the management interface differs
according to the NetDefend model as follows:
• On the NetDefend DFL-210, 260, 800, 860, 1600 and 2560, the default management interface IP
address is 192.168.1.1.
• On the NetDefend DFL-1660 and 2560G, the default management interface IP address is
192.168.10.1.
Setting the Workstation IP
The assigned NetDefend Firewall interface and the workstation interface must be on the same IP
network for inital communication between them to succeed so the static IP address of the
workstation must be set to the following values:
• IP address: 192.168.1.30
• Subnet mask: 255.255.255.0
• Default gateway: 192.168.1.1
Logging on to the Web Interface
To access the Web Interface using the factory default settings, launch a web browser on the
workstation (the latest version of Internet Explorer or Firefox is recommended) and point the
browser at the address 192.168.1.1.
When performing initial connection to NetDefendOS, the administrator must use https:// as the
URL protocol in the browser (in other words, https://192.168.1.1). Using HTTPS as the protocol
makes communication with NetDefendOS secure.
If communication with the NetDefendOS is successfully established, a user authentication dialog
similar to the one shown below will then be shown in the browser window.
Enter your username and password and click the Login button. The factory default username and
