Configuring
NAT vs. Transparent mode
Configuring
This section provides an overview of the operating modes of the FortiGate unit,
NAT/Route and Transparent, and how to configure the FortiGate unit for each
mode. There are two ways you can configure the FortiGate unit, using the
web-based manager or the command line interface (CLI). This section will step
through using both methods. Use whichever you are most comfortable with.
This section includes the following topics:
•
NAT vs. Transparent mode
•
Connecting to the FortiGate unit
•
Verify the configuration
•
Backing up the configuration
•
Additional configuration
NAT vs. Transparent mode
The FortiGate unit can run in two different modes, depending on your network
infrastructure and requirements. You have a choice between NAT/Route mode
and Transparent mode. Both include the same robust network security features
such as antispam, antivirus, VPN and firewall policies.
NAT mode
In NAT/Route mode, the FortiGate unit is visible to the network. Like a router, all
its interfaces are on different subnets.
In NAT mode, each port is on a different subnet, enabling you to have a single IP
address available to the public Internet. The FortiGate unit performs network
address translation before it sends and receives the packet to the destination
network.
In Route mode, there is no address translation.

and external networks.
192.168.1.20
You typically use NAT/Route mode when the FortiGate unit is operating as a
gateway between private and public networks. In this configuration, you would
create NAT mode firewall policies to control traffic flowing between the internal,
private network and the external, public network, usually the Internet.

Connecting to the FortiGate unit
Configuring
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 to make configuration changes. The
management IP address is also used for antivirus and attack definition updates.

functions, IPSec VPN, virus scanning, IPS web filtering, and Spam filtering.
Connecting to the FortiGate unit
To configure, maintain and administer the FortiGate unit, you need to connect to it.
There are two methods for these tasks:
•
using the web-based manger, a GUI interface using a current web browser
such as FireFox or Internet Explorer.
•
using the command line interface (CLI), a command line interface similar to
DOS or UNIX commands using an SSH terminal or Telnet terminal.
Connecting to the web-based manager
To connect to the web-based manager, you require:
•
a computer with an Ethernet connection
•
Microsoft Internet Explorer version 6.0 or higher or any recent version of the
most popular web browser
•
an Ethernet cable.
To connect to the web-based manager
16
1
Set the IP address of the management computer to the static IP address
192.168.1.2 with a netmask of 255.255.255.0.
2
Using the Ethernet cable, connect the internal interface of the FortiGate unit to the
computer Ethernet connection.

Configuring
Connecting to 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 a 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.
4
Type admin in the Name field and select Login.
Connecting to the CLI
To connect to the FortiGate CLI you require:
•
a computer with an available communications port
•
a serial cable, either a RJ-45 to DB-9 or null modem cable, whichever was
included in your FortiGate package
•
terminal emulation software such as HyperTerminal for Microsoft Windows
Note: The following procedure uses Microsoft Windows HypterTerminal software. You can
apply these steps to any terminal emulation program.
To connect to the CLI
1
Connect the serial cable to the communications port of your computer and to the
FortiGate console port.

Configure a DNS server
A DNS server is a service that converts symbolic node names to IP addresses. A
domain name server (DNS server) implements the protocol. In simple terms, it
acts as a phone book for the Internet. A DNS server matches domain names with
the computer IP address. This enables you to use readable locations, such as
fortinet.com when browsing the Internet.
DNS server IP addresses are typically provided by your internet service provider.
To configure DNS server settings
1
Go to System > Network > Options.
2
Enter the IP address of the primary DNS server.
3
Enter the IP address of the secondary DNS server.

Adding a default route and gateway
A route provides the FortiGate unit with the information it needs to forward a
packet to a particular destination. A static route causes packets to be forwarded to
a destination other than the default gateway. You define static routes manually.
Static routes control traffic exiting the FortiGate unit-you can specify through
which interface the packet will leave and to which device the packet should be
routed.
In the factory default configuration, entry number 1 in the Static Route list is
associated with a destination address of 0.0.0.0/0.0.0.0, which means any/all
destinations. This route is called the "static default route". If no other routes are
present in the routing table and a packet needs to be forwarded beyond the
FortiGate unit, the factory configured static default route causes the FortiGate unit
to forward the packet to the default gateway.

Adding firewall policies
Firewall policies enable traffic to flow through the FortiGate interfaces. Firewall
policies define how the FortiGate unit processes the packets in a communication
session. You can configure the firewall policies to allow only specific traffic, users
and specific times when traffic is allowed.
For the initial installation, a single firewall policy that enables all traffic through will
enable you to verify your configuration is working. On lower-end units such a
default firewall policy is already in place. For the higher end FortiGate units, you
will need to add a firewall policy.

Configure FortiGuard
Configure the FortiGate unit to connect to the FortiGuard Distribution Network
(FDN) to update the antivirus, antispam and IPS attack definitions.
The FDN is a world wide network of FortiGuard Distribution Servers (FDS). When
the FortiGate unit connects to the FDN, it connects to the nearest FDS. To do this,
all FortiGate units are programmed with a list of FDS addresses sorted by nearest
time zone according to the time zone configured for the FortiGate unit.
Before you can begin receiving updates, you must register your FortiGate unit
from the Fortinet web page. For information about registering your FortiGate unit,
see “Register your FortiGate unit” on page 7.
Updating antivirus and IPS signatures
After you have registered your FortiGate unit, you can update antivirus and IPS
signatures. The FortiGuard Center enables you to receive push updates, allow
push update to a specific IP address, and schedule updates for daily, weekly, or
hourly intervals.
To update antivirus definitions and IPS signatures
1
Go to System > Maintenance > FortiGuard.
2
Select the blue arrow for AntiVirus and IPS Options to expand the options.
3
Select Update Now to update the antivirus definitions.
If the connection to the FDN is successful, the web-based manager displays a
message similar to the following:
Your update request has been sent. Your database will
be updated in a few minutes. Please check your update
page for the status of the update.
After a few minutes, if an update is available, the System FortiGuard Center page
lists new version information for antivirus definitions. The System Status page also
displays new dates and version numbers for the antivirus definitions. Messages
are recorded to the event log indicating whether the update was successful or not.
Note: Updating antivirus definitions can cause a very short disruption in traffic currently
being scanned while the FortiGate unit applies the new signature database. Schedule
updates when traffic is light, for example overnight, to minimize any disruption.
For details on further FortiGuard configuration, see the FortiGate Administration
Guide.

network. This chapter describes some of these options and how to configure
them.
This chapter includes

Protection profiles
A protection profile is a group of settings you can adjust to suit your requirements
for network protection. Since protection profiles apply different protection settings
to traffic controlled by firewall policies, you can tailor the settings to the type of
traffic each policy handles.
Use protection profiles to configure:
•
antivirus protection
•
web filtering
•
web category filtering
•
spam filtering
•
content archiving
•
instant messaging filtering and access control
•
P2P access and bandwidth control
•
logging options for policies and configurations within the policies
•
rate limiting for VoIP protocols.
Using protection profiles, you can 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 policies for different traffic services to use the same
or different protection profiles.
The FortiGate unit is preconfigured with four default protection profiles. In many
cases you can use these default protection profiles, or use them as a starting
point in creating your own.
Table 1: Default protection profiles
Strict
Applies maximum protection to HTTP, FTP, IMAP, POP3, and SMTP traffic.
The strict protection profile may not be useful under normal circumstances but
it is available when maximum protection is required.
Scan
Apply virus scanning to HTTP, FTP, IMAP, POP3, and SMTP traffic.

Firewall policies
Advanced configuration
Web
Apply virus scanning and web content blocking to HTTP traffic.
Unfiltered Apply no scanning, blocking or IPS. Use the unfiltered content profile if no
content protection for content traffic is required. Add this protection profile to
firewall policies for connections between highly trusted or highly secure
networks where content does not need to be protected.
The best way to begin creating your own protection profile is to open a predefined
profile. This way you can see how a profile is set up, and then modify it suit your
requirements. You access Protection profile options by going to Firewall >
Protection Profile, and selecting Edit for one of the predefined profiles.
Protection profiles are used by the firewall policies to determine how network and
Internet traffic is controlled, scanned and when necessary, rejected. The
Protection Profiles can be considered the rules of the firewall policy. Because of
this, you should take some time to review the various options to consider what you
want the firewall policies to do. If, after setting the protection profile and firewall
policies, traffic is not flowing or flowing too much, verify your profile settings.
The number of options and configuration for the protection profile is too vast for
this document. For details on each protection profile feature and setting, see the
FortiGate Administration Guide or the FortiGate Online Help.
Firewall policies
Firewall policies are instructions the FortiGate unit uses to decide what to do with
a connection request. When the firewall receives a connection request, it analyzes
it to extract its source address, destination address, and port number.
For the connection through the FortiGate unit to be successful, the source
address, destination address, and service of the connection must match a firewall
policy. The policy directs the firewall action for the connection. The action can be
to allow the connection, deny the connection, require authentication before the
connection is allowed, or process the packet as an IPSec VPN connection.
You can configure each firewall policy to route connections or apply network
address translation (NAT) to translate source and destination IP addresses and
ports. You also add protection profiles to firewall policies to apply different
protection settings for the traffic controlled by firewall policies.
The FortiGate unit matches firewall policies by searching from the top of the
firewall policy list and moving down until it finds the first match, then performs the
required address translation, blocking and so on described by the protection
profile, then passes on the packet information. This is important, because once
the FortiGate unit finds a match to a policy, it will not continue down the list. You
need to arrange policies in the policy list from more specific to more general.
For example, if you have two policies, one that blocks specific URLs or IP
addresses, and another general policy that lets traffic through. If you put the
general policy at the top, the FortiGate unit will act on the general policy, figuring
the policy has been matched and potentially let the URLs or IPs you wanted
blocked through.
Note: No traffic will flow through a FortiGate unit until at least one firewall policy is added.

Configuring firewall policies
To add or edit a firewall policy go to Firewall > Policy and select Edit on an
existing policy, or select Create New to add a policy.
The source and destination Interface/Zone match the firewall policy with the
source and destination of a communication session. The Address Name matches
the source and destination address of the communication session.
Schedule defines when the firewall policy is enabled. While most policies are
always on, you can configure a firewall policy so that it is only on at specific times
of the day. For example, you may want to block news and entertainment sites
most of the day, except during lunch or after work, enabling your employees to
only view those sites during non-working times.
Service matches the firewall policy with the service used by a communication
session. This enables you to configure a policy for general web surfing and a
different policy specifically for other traffic such as SMTP mail or FTP uploads and
downloads.
Action defines how the FortiGate unit processes traffic. Specify an action to
accept or deny traffic or configure a firewall encryption policy.
•
Add ACCEPT policies that accept communication sessions. Using an accept
policy, you can apply FortiGate features such as virus scanning and
authentication to the communication session accepted by the policy.
•
Add DENY policies to deny communication sessions.

Antivirus options
The FortiGate unit’s antivirus configuration prevents malicious files from entering
and infecting your network environment.
The FortiGate unit uses a number of processes to scan files to ensure unwanted
files and potential attackers do not get through. The FortiGate unit scans using
these antivirus options:
•
File pattern - The FortiGate will check the file against the file pattern setting
you have configured. You can set which file names or file types the FortiGate
unit looks for in the incoming traffic.
•
Virus scan - The virus definitions are kept up to date through the FortiNet
Distribution Network. The list is updated on a regular basis so you do not have
to wait for a firmware upgrade. Note that you must register the FortiGate unit to
and purchase FortiGuard services to use virus scanning through the FDN.

AntiSpam options
Advanced configuration
•
Grayware - These are unsolicited commercial software programs that are
installed on computers, often without the user's consent or knowledge.
Grayware programs are generally considered an annoyance, but these
programs can cause system performance problems or be used for malicious
ends. The FortiGate unit scans for known grayware executable programs in
each enabled category.
•
Heuristics - The FortiGate heuristic antivirus engine performs tests on the file
to detect virus-like behavior or known virus indicators. In this way, heuristic
scanning may detect new viruses, but may also produce some false positive
results.
The antivirus elements work in sequence to give you an efficient method of
scanning incoming files. The first three elements have specific functions, the
fourth, the heuristics, is to cover any new previously unknown virus threats. The
four elements work together to offer your network unparalleled antivirus
protection. To ensure that your system is providing the most protection available,
all virus definitions and signatures are up dated regularly through the FortiGuard
antivirus services.
To configure the file patterns that the FortiGate scans, go to AntiVirus > File
Filter.
To enable grayware blocking, go to AntiVirus > Config > Grayware.
Antivirus settings are turned on in the protection profile. In the protection profile
you can enable antivirus options for specific services and which services will use
the file patterns as a part of the antivirus process.
To configure antivirus protection profile settings, go to Firewall > Protection
Profile. Select edit for a profile and select the Anti-Virus options.
For details on the antivirus features and settings, see the FortiGate Administration
Guide or the FortiGate Online Help.
AntiSpam options
The FortiGate unit’s antispam feature detects unsolicited commercial email by
identifying spam email messages and spam transmissions from known or
suspected spam servers.
This feature requires a FortiGuard subscription and a registered FortiGate unit.
When the FortiGate unit receives an email message, it verifies with the FortiGuard
server whether it is a valid email or a spam message. FortiGuard Antispam is one
of the features designed to manage spam. FortiGuard is an antispam system from
Fortinet that includes an IP address black list, a URL black list, and spam filtering
tools. The FortiGuard Center accepts submission of spam email messages as well
as well as reports of false positives.
Depending on how you configure the FortiGate unit, the FortiGate unit will either
tag the message with text so you can easily identify the spam, or delete the
message before it reaches the recipient.
The FortiGate unit also enables you to create your own spam filters using banned
words and black/white lists.

Web filtering
Banned word lists are specific words that may be typically found in email. The
FortiGate unit searches for words or patterns in email messages. If matches are
found, values assigned to the words are totalled. If the defined threshold value is
exceeded, the message is marked as spam. If no match is found, the email
message is passed along to the next filter.
You configure banned words by going to Antispam > Banned Word.
While FortiGuard services maintain a large list of known spammers, it is not
perfect. In some cases, some mail tagged as spam is an individual you want to
receive mail from, while email that is not caught by the spam filters or users you
don’t want to receive email from gets through to your inbox.
White lists and black lists enable you to maintain a list of email addresses that you
want (white list) or don’t want (black list) to receive email from. You can add or
remove addresses from lists as required. The FortiGate unit uses both an IP
address list and an email address list to filter incoming email, if enabled in the
protection profile.
When performing an IP address list check, the FortiGate unit compares the IP
address of the message's sender to the IP address list in sequence. If a match is
found, the action associated with the IP address is taken. If no match is found, the
message is passed to the next enabled spam filter.
When performing an email list check, the FortiGate unit compares the email
address of the message's sender to the email address list in sequence. If a match
is found, the action associated with the email address is taken. If no match is
found, the message is passed to the next enabled antispam filter.
To configure black/white lists, go to AntiSpam > Black/White List.
You enable antispam options for each mail service (POP3, IMAP and SMTP) in
the protection profile. To configure antispam protection profile settings, go to
Firewall > Protection Profile. Select edit for a profile and select the Spam
Filtering options.
For details on the antispam features and settings, see the FortiGate
Administration Guide or the FortiGate Online Help.
Web filtering
Web filtering is a method of controlling what web sites are viewable by users.
There are three main sections to web filtering: the Web Filter Content Block, the
URL Filter, and the FortiGuard Web filter. Each interact with each other in such a
way as to provide maximum control and protection for the Internet users.
Web filtering options are enabled and configured in the protection profile settings
by going to Firewall > Protection Profile. Select edit for a profile and selecting
either the FortiGuard Web Filtering options or the Web Filtering options. You need
to register your FortiGate unit and purchase FortiGuard services to use
FortiGuard Web Filtering.
Content blocking enables you to specify file types and words that the FortiGate
unit should block when encountered. With web content block enabled, every
requested web page is checked against the content block list. The score value of
each pattern appearing on the page is added, and if the total is greater than the
threshold value set in the protection profile, the page is blocked.

Logging
Advanced configuration
To configure content blocking, go to Web Filter > Content Block.
URL filter enables you to control additional web sites that you can block or allow.
This enables you greater control over certain URLs or sub-URLs. The FortiGate
unit allows or blocks web pages matching any specified URLs or patterns and
displays a replacement message instead.
To configure URL filters, go to Web Filter > URL Filter.
FortiGuard web filtering is a managed web filtering solution provided by Fortinet.
FortiGuard web filtering sorts hundreds of millions of web pages into a wide range
of categories users can allow, block, or monitor. FortiGuard web filtering includes
over 60 million individual ratings of web sites applying to hundreds of millions of
pages. Pages are sorted and rated into 56 categories users can allow, block, or
monitor. Categories may be added to, or updated, as the Internet evolves. You
need to have a FortiGuard subscription to take advantage of FortiGuard web
filtering.
The FortiGate unit also enables you to override the FortiGuard filtering
designation, and you can add your own. To customize your FortiGuard web
filtering, go to Web Filter > FortiGuard - Web Filter.
For details and configuration options for the web filtering features and settings,
see the FortiGate Administration Guide or the FortiGate Online Help.
Logging
Logging is an indirect method of protecting your network. The FortiGate unit’s
robust logging features enable you to see the attacks, spam and virus activity is
occurring on your network. Using this information, you can then take the corrective
action necessary to resolve any problems before they become major problems.
With alert email, you can configure the FortiGate unit to send alert messages,
when specific events occur with specific frequency. By logging to a FortiAnalyzer
unit, you can run over 300 reports on various network traffic.
To configure logging, go to Log&Report > Log Setting.
For details and configuration options for the logging features and settings, see the

This chapter describes the modem interface configuration options. The FortiGate
unit supports the modem interface only when running in NAT/Route mode.
You can configure the modem interface for stand alone mode, the direct
connection to the Internet, or for redundant mode, to act as a backup connection
to the Internet, should the primary connection fail.
This chapter includes the following topics:
•
Selecting a modem mode
•
Configuring modem settings
•
Configuring the modem using the CLI
•
Adding a Ping Server
•
Adding firewall policies for modem connections
•
Administrative access through the modem port
•
Configuring the PCMCIA modem card
Selecting a modem mode
The modem interface can work in one of two modes: redundant and stand alone
mode.
To select an operational mode for the modem interface
1
Go to System > Network > Modem.
2
Select Enable modem.
3
Select Redundant for the mode.
To select an operational mode using the CLI, type:
config system modem
set status enable
set status mode redundant
end
Redundant mode
The redundant modem interface is a backup to the external interface connected to
the Internet. If the Ethernet connection goes down for whatever reason, the
modem automatically dials the configured dial-up account(s). When the modem
connects to a dial-up account, the FortiGate unit routes IP packets normally
destined for the selected Ethernet interface to the modem interface. During this
time, the FortiGate unit pings the Ethernet connection to check when it is back
online.

Configuring modem settings
Configuring the modem interface
When the Ethernet interface can connect to its network again, the FortiGate unit
disconnects the modem interface and switches back to the Ethernet interface.
Note: Do not add firewall policies for connections between the Ethernet interface that the
modem replaces and other interfaces.
Note: Do not add a default route to the Ethernet interface that the modem interface
replaces.
Stand alone mode
In stand alone mode, the modem interface operates as the primary connection to
the Internet. The FortiGate unit routes traffic through the modem interface, which
remains permanently connected to the dial-up account.
If the connection to the dial-up account fails, the FortiGate unit modem
automatically redials the number. The modem redials the ISP number based on
the amount of times specified by the redial limit, or until it connects to a dial-up
account.
