1.2 Management
Use the Nebula Control Center (NCC)
The NSG is managed and provisioned automatically by the Nebula Control Center (NCC) when it hasis
connected to the Internet and 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 NSG’s back.

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.
