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 or DSL modems. Dual wide area network (WAN) ports
allow you to increase effective throughput 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.
The UTM provides advanced IPsec and SSL VPN technologies for secure and simple remote
connections. The use of Gigabit Ethernet LAN and WAN ports ensures extremely high data
transfer speeds.
The UTM is a plug-and-play device that can be installed and configured within minutes.

ProSecure Unified Threat Management (UTM) Appliance Reference Manual
Dual-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 mutuallyexclusive basis to:
• Provide backup and rollover if one line is inoperable, ensuring you are never disconnected.
• Load balance, or use both Internet lines simultaneously for outgoing traffic. A UTM with dualWAN ports balances users between the two lines for maximum bandwidth efficiency.
See “Network Planning for Dual WAN Ports (Dual-WAN Port Models Only)” on page B-1 for the
planning factors to consider when implementing the following capabilities with dual WAN port
gateways:
• Single or multiple exposed hosts.
• V irtual private networks.
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 1-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 pre-installed 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.
– Browser based, platform-independent, remote access through a number of popular
browsers, such as Microsoft Internet Explorer, Mozilla Firefox, or Apple Safari.
– Provides granular access to corporate resources based upon user type or group
membership.

A Powerful, True Firewall
Unlike simple Internet sharing 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.
This multithreaded approach, in which the receiving, scanning, and delivering processes occur
concurrently, ensures tha t network performance remains unimpeded. The result is 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 e-mail security, covering six major
network protocols: HTTP, HTTPS, FTP, SMTP, POP3, and IMAP. The UTM uses enterpriseclass scan engines employing both signature-based and Distributed Spam Analysis to stop
both known and unknown threats. The malware database cont ains hundreds of thousands of
signatures of spyware, viruses, and other malware.

v1.0, January 2010
ProSecure Unified Threat Management (UTM) Appliance Reference Manual
• 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,
W eb 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 normally 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 De-Militarized
Zone (DMZ) port to forward the traffic to one PC on your network.
Autosensing Ethernet Connections with Auto Uplink
With its internal 4-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 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 Uplink
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 to the
correct configuration. This feature eliminates the need 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
Requirements” on page B-3. 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 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.
(RIP). For further information about TCP/IP, see “Internet Configuration
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
your firewall from almost any type of personal computer, 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.
• Auto detection 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 to easily
configure IPsec VPN tunnels according to the recommendations of the Virtual Private
Network Consortium (VPNC) to ensure 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 to easily configure
SSL connections over VPN according to the recommendations of the VPNC to ensure 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 UTMl incorporates built-in diagnostic functions such as Ping,
Trace Route, DNS lookup, and remote reboot.
• Remote management. The UTM allows you to login 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.
