Connecting the FortiGate-50A

• Place the unit on a stable surface. It requires 1.5 inches
(3.75 cm) clearance above and on each side to allow for cooling.
• Make sure the power switch on the back of the unit is turned off before
connecting the power and network cables.
• The Status light flashes while the unit is starting up and turns off when the
system is up and running.

Planning the configuration

Quick configuration using the default settings
You can quickly set up your FortiGate unit for a home or small office using the web-
based manager and the default settings in NAT/Route mode.
All you need to do is set your network computers to use DHCP, access the web-based
manager, and configure the required settings for the external interface. You can also
configure DNS and a default route if needed. The FortiGate unit automatically assigns
IP addresses to up to 100 computers in the internal network.
1. Connect the FortiGate unit to the network.
2. Set the all the network computers to use DHCP to automatically obtain an IP
address.
The FortiGate internal interface acts as a DHCP server for the internal network and
assigns IP addresses to all computers in the range 192.168.1.110 –192.168.1.210.
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 > DNS.
NAT/Route mode
In NAT/Route mode, the FortiGate-50A is visible to the networks that it is connected to.
All of its interfaces are on different subnets. You must configure the internal and
external interfaces with IP addresses.
You would typically use NAT/Route mode when the FortiGate-50A is deployed as a
gateway between private and public networks. In its default NAT/Route mode
configuration, the unit functions as a firewall. Firewall policies control communications
through the FortiGate-50A unit.

NAT mode policies controlling
traffic between internal and
external networks.
In NAT/Route mode, firewall policies can operate in NAT mode or in Route mode. In
NAT mode, the FortiGate-50A performs network address translation before IP packets
are sent to the destination network. In Route mode, no translation takes place. By
default, the unit has a single NAT mode policy that allows users on the internal network
to securely access and download content from the Internet. No other traffic is possible
until you have configured more policies.
Refer to the Documentation CD-ROM for information on how to control traffic, and how to configure HA, antivirus protection, Web content filtering, Spam filtering, intrusion
prevention (IPS), and virtual private networking (VPN).

Before configuring the FortiGate-50A, you need to plan how to integrate the unit into your
network. You can select NAT/Route mode (the default) or Transparent mode. In NAT/Route mode
you can also use the default settings to quickly configure the unit on your network.
7. Select one of the following DNS settings
• Obtain DNS server address automatically: select to get the DNS addresses
from the ISP, select Apply
• Use the following DNS server addresses: select and enter the DNS server
addresses given to you by the ISP, select Apply
8. Go to Router > Static, select Create New, enter the default gateway address and
select OK.
Network configuration is complete. Proceed to part 7 of this Quick Start Guide.
9. Select Retrieve default gateway from server and Override internal DNS options if
your ISP supports them, select OK, and proceed to part 7 of this Quick Start Guide.
Go to step 6 if you are not selecting these options.
Internet
Transparent mode
In Transparent mode, the FortiGate-50A is invisible to the network. All of its interfaces
are on the same subnet. You only have to configure a management IP address so that
you can make configuration changes.
You would typically use the FortiGate-50A in Transparent mode on a private network
behind an existing firewall or behind a router. In its default Transparent mode
configuration, the unit functions as a firewall. By default, the unit has a single firewall
policy that allows users on the internal network segment to connect to the external
network segment. No other traffic is possible until you have configured more policies.
