Identifying Your Network Settings
User Guide 13
• An Internet connection.
The external network connection can be a cable or DSL modem with a
10/100BaseT port, an ISDN router, or a direct LAN connection. If you
have problems with your Internet connection, call your ISP (Internet
Service Provider) to correct the problem before you install the Firebox X
Edge.
Identifying Your Network Settings
You use an ISP (Internet Service Provider) to connect to the Internet.
An ISP assigns your computer or firewall an IP (Internet Protocol)
address. The IP address can be static or dynamic, and this address
lets you connect to Web sites on the Internet.
About network addressing
You must ask your ISP or corporate network administrator how your
computer gets its external IP address. Use the same method to con-
nect to the Internet with the Edge that you use with your computer.
If you connect your computer directly to the Internet with a broad-
band connection, you can put the Firebox® X 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.
You must also configure your computer to connect with a Web
browser to configure and manage the Edge. Your computer must
have an IP address in a range that is the same as the Edge. In the
factory default configuration, the Edge assigns your computer an IP
address with DHCP. You can set your computer to use DHCP and
you can then connect to the Edge to manage it. You can also give
your computer a static IP address that is in the range of the trusted
network on the Edge. For information on setting your computer to
connect to the Edge, see “Setting Your Computer to Connect to the
Edge” on page 22.
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
