Quick installation using factory defaults
The following procedure describes how to configure your internal network and the
FortiGate unit to use the FortiGate default settings.
1 Connect the FortiGate unit between the internal network and the Internet and turn
on the power.
2 Set the TCP/IP properties of the network computers to obtain an IP address
automatically and a DNS server IP address automatically (using DHCP).
3 From the management computer, browse to https://192.168.1.99.
The FortiGate web-based manager appears.
4 Go to System > Network > Interface and select Edit for the external interface.
5 Select one of the following Addressing modes:
• Manual: enter a static IP address and netmask, select OK, and go to step 6
• DHCP: to get an IP address from the ISP select DHCP and go to step 9
• PPPoE: to get an IP address from the ISP select PPPoE and go to step 9
6 Go to System > Network > Options.
You can quickly set up your FortiGate-60 series unit for a home or small office
using the web-based manager and the factory default FortiGate configuration.
All you need to do is set your network computers to obtain an IP address
automatically and to obtain DNS server IP addresses automatically (using
DHCP), access the web-based manager, and configure the required settings for
the FortiGate WAN1 interface. You can also configure FortiGate DNS servers
and add a FortiGate default route if needed.
The FortiGate internal interface acts as a DHCP server for the internal network,
automatically assigning IP addresses to computers (up to 100 computers) in the
range of 192.168.1.110 –192.168.1.210.

The FortiGate DHCP server also assigns the DNS server IP address
192.168.1.99 to each computer on the internal network. As a result, the
FortiGate unit internal interface acts as a DNS server for the internal network.
Using DNS forwarding, the FortiGate unit forwards DNS requests received from
the internal network to the DNS server IP addresses added to the FortiGate unit
configuration and returns lookup results to the internal network.

DHCP server configuration” on page 24.
