FortiGate-60R Installation and Configuration Guide Version 2.50 MR2
Introduction
The FortiGate Antivirus Firewall supports network-based deployment of
application-level services—including antivirus protection and full-scan content filtering.
FortiGate Antivirus Firewalls improve network security, reduce network misuse and
abuse, and help you use communications resources more efficiently without
compromising the performance of your network. FortiGate Antivirus Firewalls are
ICSA-certified for firewall, IPSec and antivirus services.
Your FortiGate Antivirus Firewall is a dedicated easily managed security device that
delivers a full suite of capabilities that include:
• application-level services such as virus protection and content filtering,
• network-level services such as firewall, intrusion detection, VPN, and traffic
shaping.
Your FortiGate Antivirus Firewall employs Fortinet’s Accelerated Behavior and
Content Analysis System (ABACAS™) technology, which leverages breakthroughs in
chip design, networking, security, and content analysis. The unique ASIC-based
architecture analyzes content and behavior in real-time, enabling key applications to
be deployed right at the network edge where they are most effective at protecting your
networks. The FortiGate series complements existing solutions, such as host-based
antivirus protection, and enables new applications and services while greatly lowering
costs for equipment, administration and maintenance.
The FortiGate-60 model is ideally suited
for small businesses, remote offices, retail
stores, and broadband telecommuter
sites. The FortiGate-60 Antivirus Firewall
features dual WAN link support for
redundant internet connections, and an integrated 4-port switch that eliminates the
need for an external hub or switch. Networked devices connect directly to the
FortiGate-60 unit.
The FortiGate-60R is limited to a maximum of 12 users.
Antivirus protection
FortiGate ICSA-certified antivirus protection virus scans web (HTTP), file transfer
(FTP), and email (SMTP, POP3, and IMAP) content as it passes through the
FortiGate. If a virus is found, antivirus protection removes the file containing the virus
from the content stream and forwards an replacement message to the intended
recipient.
FortiGate-60R Installation and Configuration Guide 13
Web content filtering Introduction
For extra protection, you also configure antivirus protection to block files of specified
file types from passing through the FortiGate unit. You can use the feature to stop files
that may contain new viruses.
If the FortiGate unit contains a hard disk, infected or blocked files can be quarantined.
The FortiGate administrator can download quarantined files, so that they can be virus
scanned, cleaned, and forwarded to the intended recipient. You can also configure the
FortiGate unit to automatically delete quarantined files after a specified time period.
The FortiGate unit can send email alerts to system administrators when it detects and
removes a virus from a content stream. The web and email content can be in normal
network traffic or in encrypted IPSec VPN traffic.
ICSA Labs has certified that FortiGate Antivirus Firewalls:
• detect 100% of the viruses listed in the current In The Wild List (www.wildlist.org),
• detect viruses in compressed files using the PKZip format,
• detect viruses in e-mail that has been encoded using uuencode format,
• detect viruses in e-mail that has been encoded using MIME encoding,
• log all actions taken while scanning.
Web content filtering
FortiGate web content filtering can be configured to scan all HTTP content protocol
streams for URLs or for web page content. If a match is found between a URL on the
URL block list, or if a web page is found to contain a word or phrase in the content
block list, the FortiGate blocks the web page. The blocked web page is replaced with a
message that you can edit using the FortiGate web-based manager.
You can configure URL blocking to block all or just some of the pages on a web site.
Using this feature you can deny access to parts of a web site without denying access
to it completely.
To prevent unintentional blocking of legitimate web pages, you can add URLs to an
Exempt List that overrides the URL blocking and content blocking lists.
Web content filtering also includes a script filter feature that can be configured to block
unsecure web content such as Java Applets, Cookies, and ActiveX.
You can also use the Cerberian URL blocking to block unwanted URLs.
Email filtering
FortiGate Email filtering can be configured to scan all IMAP and POP3 email content
for unwanted senders or for unwanted content. If a match is found between a sender
address pattern on the Email block list, or if an email is found to contain a word or
phrase in the banned word list, the FortiGate adds a Email tag to subject line of the
email. Receivers can then use their mail client software to filter messages based on
the Email tag.
14 Fortinet Inc.
Introduction Firewall
You can configure Email blocking to tag email from all or some senders within
organizations that are known to send spam email. To prevent unintentional tagging of
email from legitimate senders, you can add sender address patterns to an exempt list
that overrides the email block and banned word lists.
Firewall
The FortiGate ICSA-certified firewall protects your computer networks from the hostile
environment of the Internet. ICSA has granted FortiGate firewalls version 4.0 firewall
certification, providing assurance that FortiGate firewalls successfully screen for and
secure corporate networks against a wide range of threats from public or other
untrusted networks.
After basic installation of the FortiGate unit, the firewall allows users on the protected
network to access the Internet while blocking Internet access to internal networks. You
can modify this firewall configuration to place controls on access to the Internet from
the protected networks and to allow controlled access to internal networks.
FortiGate policies include a complete range of options that:
• control all incoming and outgoing network traffic,
• control encrypted VPN traffic,
• apply antivirus protection and web content filtering,
• block or allow access for all policy options,
• control when individual policies are in effect,
• accept or deny traffic to and from individual addresses,
• control standard and user defined network services individually or in groups,
• require users to authenticate before gaining access,
• include traffic shaping to set access priorities and guarantee or limit bandwidth for
each policy,
• include logging to track connections for individual policies,
• include Network address translation (NAT) mode and Route mode policies,
• include Mixed NAT and Route mode policies.
The FortiGate firewall can operate in NAT/Route mode or Transparent mode.
NAT/Route mode
In NAT/Route mode, you can create NAT mode policies and Route mode policies.
• NAT mode policies use network address translation to hide the addresses in a
more secure network from users in a less secure network.
• Route mode policies accept or deny connections between networks without
performing address translation.
FortiGate-60R Installation and Configuration Guide 15
Network intrusion detection Introduction
Transparent mode
Transparent mode provides the same basic firewall protection as NAT mode. Packets
received by the FortiGate unit are intelligently forwarded or blocked according to
firewall policies. The FortiGate unit can be inserted in your network at any point
without the need to make changes to your network or any of its components.
However, VPN and some advanced firewall features are only available in NAT/Route
mode.
Network intrusion detection
The FortiGate Network Intrusion Detection System (NIDS) is a real-time network
intrusion detection sensor that detects and prevents a wide variety of suspicious
network activity. NIDS detection uses attack signatures to identify over 1000 attacks.
You can enable and disable the attacks that the NIDS detects. You can also write your
own user-defined detection attack signatures.
NIDS prevention detects and prevents many common denial of service and packetbased attacks. You can enable and disable prevention attack signatures and
customize attack signature thresholds and other parameters.
To notify system administrators of the attack, the NIDS records the attack and any
suspicious traffic to the attack log and can be configured to send alert emails.
VPN
Fortinet updates NIDS attack definitions periodically. You can download and install
updated attack definitions manually, or you can configure the FortiGate to
automatically check for and download attack definition updates.
Using FortiGate virtual private networking (VPN), you can provide a secure
connection between widely separated office networks or securely link telecommuters
or travellers to an office network.

• PPTP for easy connectivity with the VPN standard supported by the most popular
operating systems.
• L2TP for easy connectivity with a more secure VPN standard also supported by
many popular operating systems.
• Firewall policy based control of IPSec VPN traffic.
• IPSec NAT traversal so that remote IPSec VPN gateways or clients behind a NAT
can connect to an IPSec VPN tunnel.
• VPN hub and spoke using a VPN concentrator to allow VPN traffic to pass from
one tunnel to another tunnel through the FortiGate unit.
• IPSec Redundancy to create a redundant AutoIKE key IPSec VPN connection to a
remote network.
Secure installation, configuration, and management
Installation is quick and simple. The first time you turn on the FortiGate unit, it is
already configured with default IP addresses and security policies. Connect to the
web-based manager, set the operating mode, and use the setup wizard to customize
FortiGate IP addresses for your network, and the FortiGate unit is set to protect your
network. You can then use the web-based manager to customize advanced FortiGate
features to meet your needs.
You can also create a basic configuration using the FortiGate command line interface
(CLI).
Web-based manager
Using HTTP or a secure HTTPS connection from any computer running Internet
Explorer, you can configure and manage the FortiGate unit. The web-based manager
supports multiple languages. You can configure the FortiGate unit for HTTP and
HTTPs administration from any FortiGate interface.
You can use the web-based manager for most FortiGate configuration settings. You
can also use the web-based manager to monitor the status of the FortiGate unit.
Configuration changes made with the web-based manager are effective immediately
without the need to reset the firewall or interrupt service. Once a satisfactory
configuration has been established, it can be downloaded and saved. The saved
configuration can be restored at any time.
