between these network segments.

• Internal can connect to the internal network.
• HA can connect to another network or to other FortiGate-800s if you are installing
an HA cluster.
• DMZ and interfaces 1 to 4 can connect to other network segments.
Configuration options
Once you have selected Transparent or NAT/Route mode operation, you can
complete the configuration plan and begin to configure the FortiGate unit.
You can use the web-based manager setup wizard, the control buttons and LCD, or
the command line interface (CLI) for the basic configuration of the FortiGate unit.
Setup wizard
If you are configuring the FortiGate unit to operate in NAT/Route mode (the default),
the setup wizard prompts you to add the administration password and the internal and
external interface addresses. Using the wizard, you can also add DNS server IP
addresses and a default route for the external interface.
In NAT/Route mode you can also configure the FortiGate to allow Internet access to
your internal Web, FTP, or email servers.
If you are configuring the FortiGate unit to operate in Transparent mode, you can
switch to Transparent mode from the web-based manager and then use the setup
wizard to add the administration password, the management IP address and gateway,
and the DNS server addresses.

the administration password and all interface addresses. Using the CLI, you can also
add DNS server IP addresses and a default route for the external interface.
