Preface
Intended Audience
The target audience for this reference guide is Administrators who are responsible for configuring
and managing D-Link Firewalls which are running the NetDefendOS operating system. This guide
assumes that the reader has some basic knowledge of networks and network security.
Text Structure and Conventions
The text is broken down into chapters and sub-sections. Numbered sub-sections are shown in the
table of contents at the beginning. An index is included at the end of the document to aid with
alphabetical lookup of subjects.
Where a "See chapter/section" link (such as: see Chapter 9, VPN) is provided in the main text, this
can be clicked to take the reader directly to that reference.
Text that may appear in the user interface of the product is designated by being in bold case. Where
a term is being introduced for the first time or being stressed it may appear in a italics.
Where console interaction is shown in the main text outside of an example, it will appear in a box
with a gray background.
Where a web address reference is shown in the text, clicking it will open the specified URL in a
browser in a new window (some systems may not allow this).
For example: http://www.dlink.com.
Screenshots
This guide contains a minimum of screenshots. This is deliberate and is done because the manual
deals specifically with NetDefendOS and administrators have a choice of management user
interfaces. It was decided that the manual would be less cluttered and easier to read if it concentrated
on describing how NetDefendOS functions rather than including large numbers of screenshots
showing how the various interfaces are used. Examples are given but these are largely textual
descriptions of management interface usage.
Examples
Examples in the text are denoted by the header Example and appear with a gray background as
shown below. They contain a CLI example and/or a Web Interface example as appropriate. (The
NetDefendOS CLI Reference Guide documents all CLI commands.)
Example 1. Example Notation
Information about what the example is trying to achieve is found here, sometimes with an explanatory image.
CLI
The Command Line Interface example would appear here. It would start with the command prompt followed by
the command:
gw-world:/> somecommand someparameter=somevalue
Web Interface
The Web Interface actions for the example are shown here. They are also typically a numbered list showing what
