ProSecure Unified Threat Management (UTM) Appliance
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 624. The UTM provides the following protocol support:
• IP address sharing by NAT. The UTM allows many networked computers 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 computers by DHCP. The UTM dynamically
assigns network configuration information, including IP, gateway, and Domain Name
Server (DNS) addresses, to attached computers on the LAN using the Dynamic Host
Configuration Protocol (DHCP). This feature greatly simplifies configuration of computers
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 computers. 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.
