Identifying Your Network Settings

To configure your Firebox® X Edge, you must know some information about your network. (For an
overview of network basics, see "About Networks" on page 1.) Use this section to learn how to identify
your network settings.

About network addressing

Speak with your ISP or corporate network administrator to learn how your computer gets its external IP
address. Use the same method to connect to the Internet with the Firebox X Edge that you use with
your computer. If you connect your computer directly to the Internet with a broadband connection,
you can put the Edge between your computer and the Internet and use the network configuration
from your computer to configure the Edge external interface. You can use a static IP address, DHCP, or
PPPoE to configure the Edge external interface.
Your computer must have a web browser. You use the web browser to configure and manage the Fire-
box X Edge. Your computer must have an IP address on the same network as the Edge.
In the factory default configuration, the Firebox X Edge assigns your computer an IP address with
DHCP (Dynamic Host Configuration Protocol). You can set your computer to use DHCP and then you
can connect to the Edge to manage it. You can also give your computer a static IP address that is on the
same network as the trusted IP address of the Edge. For more information, see "Setting Your Computer
to Connect to the Edge" on page 17.

Static addresses, DHCP, and PPPoE

Your ISP gives you an IP address using one of these methods:
Static: A static IP address is an IP address that always stays the same. If you have a web server, FTP
•
server, or other Internet resource that must have an address that cannot change, you can get a
static IP address from your ISP. A static IP address is usually more expensive than a dynamic IP
address, and some ISPs do not supply static IP addresses. You must configure a static IP address
manually.
DHCP: A dynamic IP address is an IP address that an ISP lets you use temporarily. ISPs use DHCP
•
(Dynamic Host Configuration Protocol) to assign you a dynamic IP address. With DHCP, your
computer does not always use the same IP address. Each time you connect to the ISP, a DHCP
server assigns you an IP address. It could be the same IP address you had before, or it could be a
new one. When you close an Internet connection that uses a dynamic IP address, the ISP can
assign that IP address to a different customer.
