NAT/Route mode installation Configuring the FortiGate unit
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 IP 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 Ta b l e 15 to
record the information you require for your PPPoE configuration.
