About the Secure Firewall Management Center 1700, 2700, and 4700

Review Network Deployment

By default, the management center connects to your local management network through its management

interface (eth0). This connection the management center communicates with a management computer, managed

devices, services such as DHCP, DNS, NTP, and the internet.

The management center requires internet access to support Smart Licensing, Secure Firewall threat intelligence

director, and malware defense services. Depending on the services provided by your local management

network, the management center may also require internet access to reach an NTP or DNS server. You can

configure your network to provide internet access to the management center directly or through a firewall

device.

You can upload updates for system software, Vulnerability Database (VDB), Geolocation Database (GeoDB),

and intrusion rules directly to the management center from an internet connection or from a local computer

that has these updates from the internet.

To establish the connection between the management center and one of its managed devices, you need the IP

address of at least one of the devices: the management center or the managed device. We recommend using

both IP addresses if available. However, you may only know one IP address. For example, managed devices

may be using private addresses behind NAT, so you only know the management center address. In this case,

you can specify the management center address on the managed device plus a one-time, unique password of

your choice called a NAT ID. On the management center, you specify the same NAT ID to identify the

managed device.

The initial setup and configuration described in this document is for a management center that has internet

access. If you deploy a management center in an air-gapped environment, see the
