About This Manual xv
Chapter 1
Introduction
This chapter describes the features of the NETGEAR FR328S Cable/DSL ProSafe Firewall with
Dial Back-Up.
About the FR328S
The FR328S is a c omplete securit y solut ion that protec ts your network f rom at tacks a nd intru sions.
Unlike simple Internet sharing routers that rely on Network Address Translation (NAT) for
security, the FR328S uses S ta teful Pack et I nspect ion for Den ial of Ser vice (Do S) atta ck pro tection
and intrusion detectio n. The 8-port FR328S with aut o fail-over conn ectiv ity through the serial port
provides highly reliable Internet access for up to 253 users.
Key Features
The FR328S o ffers the followin g features.
A Powerful, True Firewall
Unlike simple Internet sharing NAT routers, the FR328S is a true firew all, using stateful packet
inspection to defend against hacker attacks. Its firewall features include:
• Denial of Service (DoS) protection
Automatically detects and thwarts Denial of Service (DoS) attacks such as Ping of Death,
SYN Flood, LAND Attack and IP Spoofing.
• Blocks unwanted traffic from the Internet to your LAN.
• Blocks access from your LAN to Internet locations or services that you specify as off-limits.
Introduction 1-1
FR328S Cable/DSL ProSafe Firewall with Dial Back-Up
• Logs security incidents
The FR328S will log security events suc h as blocke d inco ming traffic, port scans, attack s, 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.
Content Filtering
With its content filtering feature, the FR328S prevents objectionable content from reaching your
PCs. The firewall allows you to control access to Internet content by screening for keywords
within Web addresses. You can configure the firewall to log and report attempts to access
objectionable Internet sites.
Configurable Auto Uplink™ Ethernet Connection
With its internal 8-port 10/100 switch, the FR328S can connect to either a 10 Mbps standard
Ethernet network or a 10 0 Mbps Fast Etherne t net work . Both the l ocal LAN and the I ntern et WAN
interfaces are autosensing and capable of full-duplex or half-duplex operation.
The firewall incorporates Auto UplinkTM technology. Each LOCAL Ethernet port will
automatically sense whether the Ethernet cable plugged into the port should have a ‘normal’
connection such as to a PC or an ‘uplin k’ connecti on such as to a switch or hub. Th at port wil l then
configure itself to the correct configuration. This feature also eliminates the need to worry about
crossover cables, as Auto Uplink will accommodate either type of cable to make the right
connection.
Protocol Support
The FR328S supports the Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing
Information Protocol (RIP).
further information on TCP/IP.
• IP Address Sharing by NAT
The FR328S allows severa l ne tworked PCs to share an Inte rne t ac count using only a single IP
address, which may 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.
1-2 Introduction
Appendix B, “Networks, Routing, and Firewall Basics” provides
FR328S Cable/DSL ProSafe Firewall with Dial Back-Up
• Automatic Configuration of Attached PCs by DHCP
The FR328S dynamically assigns network configuration information, including IP, gateway,
and domain name server (DNS) addre sses, 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)
PPP over Ethernet is a protocol for connecting remote hosts to the Internet over a DSL
connection by simulating a dial-up connection. This feature eliminates the need to run a login
program such as EnterNet or WinPOET on your PC.
• PPTP login support for European ISPs, BigPond login for Telstra cable in Australia.
•Dynamic DNS
Dynamic DNS services allow remote users to find your network using a domain name when
your IP address is not pe rman ent ly assigned. The firewall contai ns a client that can connect to
many popular Dynamic DNS services to register your dynamic IP address.
Easy Installation and Management
You can install, configure, and operate the FR328S 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.
• Smart Wizard
The firewall automatically senses the type of Internet connection, asking you only for the
information required for your type of ISP account.
• Auto fail-over connectivity through an analog or ISDN modem connected to the serial port
If the cable or DSL modem I ntern et c onnect ion f ails , aft er a wait ing f or a n amount o f time you
specify, the FR328S c an aut omatic ally e stabl ish a backup ISDN or di al-u p Inte rnet connect ion
via the serial port on the firewall.
Introduction 1-3
FR328S Cable/DSL ProSafe Firewall with Dial Back-Up
• Remote management
The firewall allows you to logi n t o the W eb Management Interface from a re mo te loc ati on vi a
the Internet. For security, you can limi t remote management access to a specified remote IP
address or range of addresses, and you can choose a nonstandard port number.
• Remote Access Server connectivity vial the serial port
• Diagnostic functions
The firewall incorporates built-in diagnostic functions such as Ping, DNS lookup, and remote
reboot. These functi ons allow you to test Inter net conne ctivity and reboot the fi rewall. You can
use these diagnostic f unctions di rectly from the FR328S when your are conne ct on the LAN or
when you are connected over the Internet via the remote management function.
• Visual monitoring
The firewall’s front panel LEDs provide an easy way to monitor its status and activity.
• Flash EPROM for firmware upgrade
• Regional support, including ISPs like Telstra DSL and BigPond or Deutsche Telekom.

Note: The FR328S Firewall incorporates Auto UplinkTM technology. Each LOCAL Ethernet
port will automatically sense whether the cable plugged into the port should have a 'normal'
connection (e.g. connecting to a PC) or an 'uplink' connection (e.g. connecting to a switch or
hub). That port will then configure itself to the correct configuration. This feature also
eliminates the need to worry about crossover cables, as Auto Uplink will accommodate either
type of cab le to make the right connec tion.
e. Turn on the Cable or DSL modem and wait about 30 seconds for the lights to stop
blinking.
2. Log in to the Firewall

Connecting the FR328S Firewall to the Internet
The firewall is now properly attached to your network. You are now ready to configure your
firewall to connect to the Internet. There are two ways you can configure your firewall to connect
to the Internet:
• Let the FR328S auto-detect the type of Internet connection you have and configure it.
• Manually choose which type of Internet connection you have and configure it.
These options are described below. In either case, unless your ISP automatically assigns your
configuration automatically via DHCP, you will need the configuration parameters from your ISP
you recorded in “Record Your Internet Connection Information” on page 2-3.
