Connecting to the FortiGate unit Installing the FortiGate unit
To support a secure HTTPS authentication method, the FortiGate unit ships with a
self-signed security certificate, which is offered to remote clients whenever they
initiate a HTTPS connection to the FortiGate unit. When you connect, the
FortiGate unit displays two security warnings in the browser.
The first warning prompts you to accept and optionally install the FortiGate unit’s
self-signed security certificate. If you do not accept the certificate, the FortiGate
unit refuses the connection. If you accept the certificate, the FortiGate login page
appears. The credentials entered are encrypted before they are sent to the
FortiGate unit. If you choose to accept the certificate permanently, the warning is
not displayed again.
Just before the FortiGate login page is displayed, a second warning informs you
that the FortiGate certificate distinguished name differs from the original request.
This warning occurs because the FortiGate unit redirects the connection. This is
an informational message. Select OK to continue logging in.

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.
1Connect the FortiGate unit between the internal network and the Internet and turn
on the power.
2Set the TCP/IP properties of the network computers to obtain an IP address
automatically and a DNS server IP address automatically (using DHCP).
3From the management computer, browse to https://192.168.1.99.
4Go to System > Network > Interface and select Edit for the External or WAN1
interface.
5Select 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 Internet Service Provider (ISP) select
DHCP and go to step 9
• PPPoE: to get an IP address from the ISP select PPPoE and go to step 9
You can quickly set up your FortiGate 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
external 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.
Figure 6: Quick configuration using default settings
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.
For more information about default DHCP server settings see “Factory default
DHCP server configuration” on page 28.

Factory defaults
The FortiGate unit ships with a factory default configuration. The default
configuration enables you to connect to and use the FortiGate web-based
manager to configure the FortiGate unit onto the network. To configure the
FortiGate unit, you add an administrator password, change network interface IP
addresses, add DNS server IP addresses, and, if required, configure basic
routing.
If you plan to operate the FortiGate unit in Transparent mode, you can switch to
Transparent mode from the factory default configuration and then configure the
FortiGate unit onto the network.
Once you complete the network configuration, you can perform additional
configuration tasks such as setting system time, configuring virus and attack
definition updates, and registering the FortiGate unit.
The factory default firewall configuration includes a single network address
translation (NAT) policy that allows users on your internal network to connect to
the external network, and stops users on the external network from connecting to
the internal network. You can add more firewall policies to provide more control of
the network traffic passing through the FortiGate unit.
You can use the factory default protection profiles to apply different levels of
antivirus protection, web content filtering, spam filtering, and IPS to the network
traffic that is controlled by firewall policies.

Table 10: Factory default firewall configuration
The factory default firewall configuration is the same in NAT/Route mode and
Transparent mode.
Factory default protection profiles
Use protection profiles to apply different protection settings for traffic controlled by
firewall policies. You can use protection profiles to:
• configure antivirus protection for HTTP, FTP, IMAP, POP3, and SMTP firewall
policies
• configure Web filtering for HTTP firewall policies
• configure Web category filtering for HTTP firewall policies
• configure spam filtering for IMAP, POP3, and SMTP firewall policies
• enable the Intrusion Protection System (IPS) for all services
• enable content logging for HTTP, FTP, IMAP, POP3, and SMTP firewall
policies
By using protection profiles, you can build protection configurations that can be
applied to different types of firewall policies. This allows you to customize types
and levels of protection for different firewall policies.
For example, while traffic between internal and external addresses might need
strict protection, traffic between trusted internal addresses might need moderate
protection. You can configure firewall policies for different traffic services to use
the same or different protection profiles.
You can add Protection profiles to NAT/Route mode and Transparent mode
firewall policies. The FortiGate unit includes four protection profiles.

Configuring the FortiGate unit
This section provides an overview of the operating modes of the FortiGate unit.
Before beginning to configure the FortiGate unit, you need to plan how to
integrate the unit into your network. Your configuration plan depends on the
operating mode you select: NAT/Route mode or Transparent mode.
This section includes the following topics:
•Planning the FortiGate configuration
•Preventing the public interface from responding to ping requests
•NAT/Route mode installation
•Transparent mode installation
•Next steps
Planning the FortiGate configuration
Before you configure the FortiGate unit, you need to plan how to integrate the unit
into the network. Among other things, you must decide whether you want the unit
to be visible to the network, which firewall functions you want it to provide, and
how you want it to control the traffic flowing between its interfaces.
Your configuration plan depends on the operating mode you select. You can also
configure the FortiGate unit and the network it protects using the default settings.
NAT/Route mode
In NAT/Route mode, the FortiGate unit is visible to the network. Like a router, all
its interfaces are on different subnets. The following interfaces are available in
NAT/Route mode:
Modem is the interface for connecting an external modem to the FortiGate-50A.
See “Configuring the modem for the FortiGate-50A” on page 53.
You can add firewall policies to control whether communications through the
FortiGate unit operating in NAT or Route mode. Firewall policies control the flow
of traffic based on the source address, destination address, and service of each
packet. In NAT mode, the FortiGate unit performs network address translation
before it sends the packet to the destination network. In Route mode, there is no
address translation.

Planning the FortiGate configuration Configuring the FortiGate unit
You typically use NAT/Route mode when the FortiGate unit is operating as a
gateway between private and public networks. In this configuration, you create
NAT mode firewall policies to control traffic flowing between the internal, private
network and the external, public network (usually the Internet).
Figure 7: Example NAT/Route mode network configuration for a FortiGate-50A.
.
NAT/Route mode with multiple external network connections
In NAT/Route mode, you can configure the FortiGate unit with multiple redundant
connections to the external network (usually the Internet).
For example, you could create the following configuration:
• External or WAN1 is the default interface to the external network (usually the
Internet)
• Modem is the redundant interface to the external network for the
FortiGate-50A
• WAN2 is the redundant interface to the external network on the FortiGate-50B
and FortiWiFi-50B.
• DMZ is the redundant interface to the external network on the FortiGate-100
• Internal is the interface to the internal network
You must configure routing to support redundant Internet connections. Routing
can automatically redirect connections from an interface if its connection to the
external network fails.
Otherwise, security policy configuration is similar to a NAT/Route mode
configuration with a single Internet connection. You would create NAT mode
firewall policies to control traffic flowing between the internal, private network and
the external, public network (usually the Internet).

Transparent mode
In Transparent mode, the FortiGate unit is invisible to the network. Similar to a
network bridge, all FortiGate interfaces must be on the same subnet. You only
have to configure a management IP address so that you can make configuration
changes. The management IP address is also used for antivirus and attack
definition updates.
You typically use the FortiGate unit in Transparent mode on a private network
behind an existing firewall or behind a router. The FortiGate unit performs firewall
functions, IPSec VPN, virus scanning, IPS web content filtering, and Spam
filtering.

Preventing the public interface from responding to ping
requests
The factory default configuration of your FortiGate unit allows the default public
interface to respond to ping requests. The default public interface is also called
the default external interface, and is the interface of the FortiGate unit that is
usually connected to the Internet.
For the most secure operation, you should change the configuration of the
external interface so that it does not respond to ping requests. Not responding to
ping requests makes it more difficult for a potential attacker to detect your
FortiGate unit from the Internet.
A FortiGate unit responds to ping requests if ping administrative access is
enabled for that interface. You can use the following procedures to disable ping
access for the external interface of a FortiGate unit. You can use the same
procedure for any FortiGate interface. You can also use the same procedure in
NAT/Route or Transparent mode.

NAT/Route mode installation
This section describes how to install the FortiGate unit in NAT/Route mode. This
section includes the following topics:
•Preparing to configure the FortiGate unit in NAT/Route mode
•DHCP or PPPoE configuration
•Using the web-based manager
•Using the command line interface
•Connecting the FortiGate unit to the network(s)
•Configuring the networks
Preparing to configure the FortiGate unit in NAT/Route mode
Use Table 12 on page 36 to gather the information you need to customize
NAT/Route mode settings.
You can configure the FortiGate unit in two ways:
• The web-based manager GUI is a complete interface for configuring most
settings. See “Using the web-based manager” on page 37.
• The command line interface (CLI) is a complete text-based interface for
configuring all settings. See “Using the command line interface” on page 39.
The method you choose depends on the complexity of the configuration, access
and equipment, and the type of interface you are most comfortable using.

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 Table 13 to
record the information you require for your PPPoE configuration.
Table 13: PPPoE setting
Using the web-based manager
You can use the web-based manager for the initial configuration of the FortiGate
unit and all FortiGate unit settings. For information about connecting to the
web-based manager, see “Connecting to the web-based manager” on page 21.
Configuring basic settings
After connecting to the web-based manager, use the following procedures to
complete the basic configuration of the FortiGate unit.

Add a default route to configure where the FortiGate unit sends traffic destined for
an external network (usually the Internet). Adding the default route also defines
which interface is connected to an external network. The default route is not
required if the interface connected to the external network is configured using
DHCP or PPPoE.
To add a default route
1Go to Router > Static.
2If the Static Route table contains a default route (IP and Mask set to 0.0.0.0),
select the Delete icon to delete this route.
3Select Create New.
Note: If you change the IP address of the interface you are connecting to, you must
connect through a web browser again using the new address. Browse to https:// followed
by the new IP address of the interface. If the new IP address of the interface is on a
different subnet, you may have to change the IP address of your computer to the same
subnet.
