Preparing to configure NAT/Route mode NAT/Route mode installation
To use the factory default configuration, follow these steps to install the FortiGate unit:
1 Configure the TCP/IP settings of the computers on your internal network to obtain an
IP address automatically using DHCP. Refer to your computer documentation for
assistance.
2 Complete the procedure in the section “Connecting the FortiGate unit to your
networks” on page 37 .
Changing the default configuration
You can use the procedures in this chapter to change the default configuration. For
example, if your ISP assigns IP addresses using PPPoE instead of DHCP, you only
need to change the configuration of the external interface. Use the information in the
rest of this chapter to change the default configuration as required.
Preparing to configure NAT/Route mode
Use Table 12 to gather the information that you need to customize NAT/Route mode
settings.
