What Is the ProSecure Unified Threat Management (UTM)
Appliance?
The ProSecure Unified Threat Management (UTM) Appliance, hereafter referred to as the
UTM, connects your local area network (LAN) to the Internet through one or two external
broadband access devices such as cable modems, DSL modems, satellite dishes, or
wireless ISP radio antennas, or a combination of those. Dual wide area network (WAN) ports
allow you to increase the effective data rate to the Internet by utilizing both WAN ports to
carry session traffic, or to maintain a backup connection in case of failure of your primary
Internet connection.
As a complete security solution, the UTM combines a powerful, flexible firewall with a content
scan engine that uses NETGEAR Stream Scanning technology to protect your network from
denial of service (DoS) attacks, unwanted traffic, traffic with objectionable content, spam,
phishing, and web-borne threats such as spyware, viruses, and other malware threats.

ProSecure Unified Threat Management (UTM) Appliance
Multiple WAN Port Models for Increased Reliability or
Outbound Load Balancing
The UTM product line offers models with two broadband WAN ports. The second WAN port
allows you to connect a second broadband Internet line that can be configured on a mutually
exclusive basis to:
• Provide backup and rollover if one line is inoperable, ensuring that you are never
disconnected.
• Load balance, or use both Internet lines simultaneously for outgoing traffic. A UTM with
dual WAN ports balances users between the two lines for maximum bandwidth efficiency.
See Appendix C, Network Planning for Dual WAN Ports (Multiple WAN Port Models Only) for
the planning factors to consider when implementing the following capabilities with dual WAN
port gateways:
• Single or multiple exposed hosts
• Virtual private networks
Wireless Features
Wireless client connections are supported on the UTM9S with a UTM9SWLSN wireless
module installed. The UTM9S supports the following wireless features:
• 2.4-GHz radio and 5-GHz radio. Either 2.4-GHz band support with 802.11b/g/n/ wireless
modes or 5-GHz band support with 802.11a/n wireless modes.
• WMM QoS priority. Wi-Fi Multimedia (WMM) Quality of Service (QoS) priority settings to
map one of four queues to each Differentiated Services Code Point (DSCP) value.
• Wireless Distribution System (WDS). WDS enables expansion of a wireless network
through two or more access points that are interconnected.
• Access control. The Media Access Control (MAC) address filtering feature can ensure

Advanced VPN Support for Both IPSec and SSL
The UTM supports IPSec and SSL virtual private network (VPN) connections.
• IPSec VPN delivers full network access between a central office and branch offices, or
between a central office and telecommuters. Remote access by telecommuters requires
the installation of VPN client software on the remote computer.
-IPSec VPN with broad protocol support for secure connection to other IPSec
gateways and clients.
-Depending on the model, bundled with a one-user license of the NETGEAR ProSafe
VPN Client software (VPN01L).
• SSL VPN provides remote access for mobile users to selected corporate resources
without requiring a preinstalled VPN client on their computers.
-Uses the familiar Secure Sockets Layer (SSL) protocol, commonly used for
e-commerce transactions, to provide client-free access with customizable user portals
and support for a wide variety of user repositories.
-Allows browser-based, platform-independent remote access through a number of
popular browsers, such as Microsoft Internet Explorer, Mozilla Firefox, and Apple
Safari.
-Provides granular access to corporate resources based on user type or group
membership.
A Powerful, True Firewall
Unlike simple NAT routers, the UTM is a true firewall, using Stateful Packet Inspection (SPI)
to defend against hacker attacks. Its firewall features have the following capabilities:
• DoS protection. Automatically detects and thwarts denial of service (DoS) attacks such
as Ping of Death and SYN flood.
• Secure firewall. Blocks unwanted traffic from the Internet to your LAN.
• Schedule policies. Permits scheduling of firewall policies by day and time.
• Logs security incidents. Logs security events such as blocked incoming traffic, port
scans, attacks, and administrator logins. You can configure the firewall to email the log to
you at specified intervals. You can also configure the firewall to send immediate alert
messages to your email address or email pager whenever a significant event occurs.
Stream Scanning for Content Filtering
Stream Scanning is based on the simple observation that network traffic travels in streams.
The UTM scan engine starts receiving and analyzing traffic as the stream enters the network.
As soon as a number of bytes are available, scanning starts. The scan engine continues to
scan more bytes as they become available, while at the same time another thread starts to
deliver the bytes that have been scanned.
Introduction
17
ProSecure Unified Threat Management (UTM) Appliance
This multithreaded approach, in which the receiving, scanning, and delivering processes
occur concurrently, ensures that network performance remains unimpeded. The result is that
file scanning is up to five times faster than with traditional antivirus solutions—a performance
advantage that you will notice.
Stream Scanning also enables organizations to withstand massive spikes in traffic, as in the
event of a malware outbreak. The scan engine has the following capabilities:
• Real-time protection. The patent-pending Stream Scanning technology enables
scanning of previously undefended real-time protocols, such as HTTP. Network activities
susceptible to latency (for example, web browsing) are no longer brought to a standstill.
• Comprehensive protection. Provides both web and email security, covering six major
network protocols: HTTP, HTTPS, FTP, SMTP, POP3, and IMAP. The UTM uses
enterprise-class scan engines employing both signature-based and distributed spam
analysis to stop both known and unknown threats. The malware database contains
hundreds of thousands of signatures of spyware, viruses, and other malware.
• Objectionable traffic protection. The UTM prevents objectionable content from
reaching your computers. You can control access to the Internet content by screening for
web services, web addresses, and keywords within web addresses. You can log and
report attempts to access objectionable Internet sites.
• Automatic signature updates. Malware signatures are updated as frequently as every
hour, and the UTM can check automatically for new signatures as frequently as every 15
minutes.
Security Features
The UTM is equipped with several features designed to maintain security:
• PCs hidden by NAT. NAT opens a temporary path to the Internet for requests originating
from the local network. Requests originating from outside the LAN are discarded,
preventing users outside the LAN from finding and directly accessing the computers on
the LAN.
• Port forwarding with NAT. Although NAT prevents Internet locations from directly
accessing the PCs on the LAN, the UTM allows you to direct incoming traffic to specific
PCs based on the service port number of the incoming request. You can specify
forwarding of single ports or ranges of ports.
• DMZ port. Incoming traffic from the Internet is usually discarded by the UTM unless the
traffic is a response to one of your local computers or a service for which you have
configured an inbound rule. Instead of discarding this traffic, you can use the dedicated
demilitarized zone (DMZ) port to forward the traffic to one PC on your network.
Autosensing Ethernet Connections with Auto Uplink
With its internal four- or six-port 10/100/1000 Mbps switch and single or dual
(model-dependant) 10/100/1000 WAN ports, the UTM can connect to either a 10 Mbps
standard Ethernet network, a 100 Mbps Fast Ethernet network, or a 1000 Mbps Gigabit
Introduction
18
ProSecure Unified Threat Management (UTM) Appliance
Ethernet network. The four LAN and one or two WAN interfaces are autosensing and capable
of full-duplex or half-duplex operation.
The UTM incorporates Auto UplinkTM technology. Each Ethernet port automatically senses
whether the Ethernet cable plugged into the port should have a normal connection such as to
a PC or an uplink connection such as to a switch or hub. That port then configures itself
correctly. This feature eliminates the need for you to think about crossover cables, as Auto
Uplink accommodates either type of cable to make the right connection.
Extensive Protocol Support
The UTM supports the Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing
Information Protocol (RIP). For further information about TCP/IP, see Internet Configuration
Requirements on page 558. The UTM provides the following protocol support:
• IP address sharing by NAT. The UTM allows many networked PCs to share an Internet
account using only a single IP address, which might be statically or dynamically assigned
by your Internet service provider (ISP). This technique, known as Network Address
Translation (NAT), allows the use of an inexpensive single-user ISP account.
• Automatic configuration of attached PCs by DHCP. The UTM dynamically assigns
network configuration information, including IP, gateway, and Domain Name Server
(DNS) addresses, to attached PCs on the LAN using the Dynamic Host Configuration
Protocol (DHCP). This feature greatly simplifies configuration of PCs on your local
network.
• DNS proxy. When DHCP is enabled and no DNS addresses are specified, the firewall
provides its own address as a DNS server to the attached PCs. The firewall obtains
actual DNS addresses from the ISP during connection setup and forwards DNS requests
from the LAN.
• PPP over Ethernet (PPPoE). PPPoE is a protocol for connecting remote hosts to the
Internet over a DSL connection by simulating a dial-up connection.
• Quality of Service (QoS). The UTM supports QoS, including traffic prioritization and
traffic classification with Type of Service (ToS) and Differentiated Services Code Point
(DSCP) marking.
Easy Installation and Management
You can install, configure, and operate the UTM within minutes after connecting it to the
network. The following features simplify installation and management tasks:
• Browser-based management. Browser-based configuration allows you to easily
configure the UTM from almost any type of operating system, such as Windows,
Macintosh, or Linux. A user-friendly Setup Wizard is provided, and online help
documentation is built into the browser-based web management interface.
• Autodetection of ISP. The UTM automatically senses the type of Internet connection,
asking you only for the information required for your type of ISP account.

• IPSec VPN Wizard. The UTM includes the NETGEAR IPSec VPN Wizard so you can
easily configure IPSec VPN tunnels according to the recommendations of the Virtual
Private Network Consortium (VPNC). This ensures that the IPSec VPN tunnels are
interoperable with other VPNC-compliant VPN routers and clients.
• SSL VPN Wizard. The UTM includes the NETGEAR SSL VPN Wizard so you can easily
configure SSL connections over VPN according to the recommendations of the VPNC.
This ensures that the SSL connections are interoperable with other VPNC-compliant
VPN routers and clients.
• SNMP. The UTM supports the Simple Network Management Protocol (SNMP) to let you
monitor and manage log resources from an SNMP-compliant system manager. The
SNMP system configuration lets you change the system variables for MIB2.
• Diagnostic functions. The UTM incorporates built-in diagnostic functions such as ping,
traceroute, DNS lookup, and remote reboot.
• Remote management. The UTM allows you to log in to the web management interface
from a remote location on the Internet. For security, you can limit remote management
access to a specified remote IP address or range of addresses.
