• The front control buttons and LCD provide access to basic settings. See
“Using the front control buttons and LCD” on page 37.
• The command line interface (CLI) is a complete text-based interface for
configuring all settings. See “Using the command line interface” on page 38.
The method you choose depends on the complexity of the configuration, access
and equipment, and the type of interface you are most comfortable using.

DHCP or PPPoE configuration
You can configure any FortiGate interface to acquire its IP address from a DHCP
or PPPoE server. Your Internet Service Provider (ISP) may provide addresses
using one of these protocols.
To use the FortiGate DHCP server, you need to configure an IP address range
and default route for the server. No configuration information is required for
interfaces that are configured to use DHCP.
PPPoE requires you to supply a user name and password. In addition, PPPoE
unnumbered configurations require you to supply an IP address. Use Table 14 to
record the information you require for your PPPoE configuration.
