1.1 Overview

This chapter introduces the main features and applications of the NSG. The NSG Series consists of the following models:

•NSG50

• NSG100

• NSG200

• NSG300

The NSG (Nebula Security Gateway) comes with one or two USB ports for storing the packet capture files and/or diagnostic information in the connected USB storage devices.

The following is a hardware comparison table.

1.2 Management

Use the Nebula Control Center (NCC)

The NSG is managed and provisioned automatically by the Nebula Control Center (NCC) when it has connected to the Internet and has been registered to a site and organization. Register the NSG by entering its MAC address and serial number. The serial number and MAC address can be found in the Status screen or the device back label on the NSG.

NSG Series User’s Guide

Chapter 1 Introduction

If the NSG is registered to a site in the NCC and its firmware is not up-to-date, the NSG firmware will be upgraded according to the device-specific schedule or the site-wide schedule configured in the NCC.

Go to the NCC to configure the following settings:

•VPN

• Firewall

• IDP (Intrusion Detection and Protection)

• Content filtering

•Anti-virus

• Application patrol

•Bandwidth management

• NAT

•Port forwarding

• Policy routing

•DHCP server

Use the Web Configurator

This User's Guide shows you how to use the web configurator.

Access the NSG’s built-in Web Configurator to:

• Check the Internet connection if the NSG can’t be managed by the NCC

• Check the system status

• Configure WAN connection settings

• Collect diagnostic information

NSG Series User’s Guide

Chapter 1 Introduction

Note: The configuration settings of the NSG will be overwritten with what you have configured

in the NCC.

The NSG’s default static IP address is 192.168.1.1, but you need to use the console port or check the NCC's Gateway > Configure > Interface addressing screen for the NSG's current LAN IP address when the NSG is being managed or has been managed by the NCC.

See the Quick Start Guide for how to make hardware connections.

1.3 Ways to Manages the NSG

You can manage the NSG in the following ways.

NCC (Nebula Control Center)

With the NCC, you can remotely manage and monitor the NSG through a cloud-based network management system. See the NCC User’s Guide for detailed information about how to access the NCC and manage your NSG via the NCC.

Web Configurator

The built-in Web Configurator allows basic NSG setup and monitoring using an Internet browser. This User’s Guide provides information about the Web Configurator.

Figure 1 Managing the NSG: Web Configurator

1.4 Good Habits for Managing the NSG

Do the following things to make the NSG more secure and to manage it more effectively.

• Change the NSG’s system password through the NCC occasionally. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.

• Write down the password and put it in a safe place.

NSG Series User’s Guide

This chapter describes the front panels and rear panels of the NSG and shows you how to make the hardware connections.
