Introduction 2-1
December 2003, M-10177-01
Chapter 2
Introduction
This chapter describes the features of the NETGEAR ProSafe Wireless 802.11g Firewall/Print
Server Model FWG114P.
Key Features of the FWG114P
The ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P with a 4-port switch
connects your LAN to the Internet through a broadband modem. With auto fail-over connectivity
through the serial port, the FWG114P provides highly reliable Internet access.
The FWG114P is a complete security solution that protects your network from attacks and
intrusions. Unlike simple Internet sharing routers that rely on Network Address Translation (NAT)
for security, the FWG114P uses Stateful Packet Inspection for Denial of Service attack (DoS)
attack protection and intrusion detection. The FWG114P allows Internet access for up to 253
users. The FWG114P Wireless Firewall/Print Server provides you with multiple Web content
filtering options, plus browsing activity reporting and instant alerts via e-mail. Parents and
network administrators can establish restricted access policies based on time-of-day, Web site
addresses and address keywords, and share high-speed cable/DSL Internet access for up to 253
personal computers. In addition to NAT, the built-in firewall protects you from hackers.
With minimum setup, you can install and use the router within minutes. The FWG114P Wireless
Firewall/Print Server provides the following features:
• 802.11g and 802.11b standards-based wireless networking.
• Easy, Web-based setup for installation and management.
• Content Filtering and Site Blocking Security.
• Built in 4-port 10/100 Mbps Switch.
• Ethernet connection to a WAN device, such as a cable modem or DSL modem.
• Extensive Protocol Support.
• Login capability.
• Front panel LEDs for easy monitoring of status and activity.
• Flash memory for firmware upgrade.

Reference Manual for the ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P
2-2 Introduction
December 2003, M-10177-01
Full Routing on Both the Broadband and Serial Ports
You can install, configure, and operate the FWG114P to take full advantage of a variety of routing
options on both the serial and broadband WAN ports, including:
• Internet access via either the serial or broadband port.
• Auto fail-over connectivity through an analog or ISDN modem connected to the serial port.
If the broadband Internet connection fails, after a waiting for an amount of time you specify,
the FWG114P can automatically establish a backup ISDN or dial-up Internet connection via
the serial port on the firewall.
• Remote Access Server (RAS) allows you to log in remotely through the serial port to access a
server on your LAN, other LAN resources, or the Internet based on a user name and password
you define.
• LAN-to-LAN access between two FWG114P wireless firewall/print servers through the serial
port with the option of enabling auto-failover Internet access across the serial LAN-to-LAN
connection.
802.11g and 802.11b Wireless Networking
The FWG114P Wireless Firewall/Print Server includes an 802.11g-compliant wireless access
point. The access point provides:
• 802.11b standards-based wireless networking at up to 11 Mbps.
• 802.11g wireless networking at up to 54 Mbps, which conforms to the 802.11g standard.
• WPA enterprise class strong security with RADIUS and certificate authentication as well as
dynamic encryption key generation.
• WPA-PSK pre-shared key authentication without the overhead of RADIUS servers but with
all of the strong security of WPA.
• 64-bit and 128-bit WEP encryption security.
• WEP keys can be generated manually or by passphrase.
• Wireless access can be restricted by MAC Address.
• Wireless network name broadcast can be turned off so that only devices that have the network
name (SSID) can connect.

Introduction 2-3
December 2003, M-10177-01
A Powerful, True Firewall with Content Filtering
Unlike simple Internet sharing NAT routers, the FWG114P is a true firewall, using stateful packet
inspection to defend against hacker attacks. Its firewall features include:
• DoS protection.
Automatically detects and thwarts 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.
• Logs security incidents.
The FWG114P will log security events such as blocked incoming traffic, port scans, attacks,
and administrator logins. You can configure the router to email the log to you at specified
intervals. You can also configure the router to send immediate alert messages to your email
address or email pager whenever a significant event occurs.
• With its content filtering feature, the FWG114P prevents objectionable content from reaching
your PCs. The router allows you to control access to Internet content by screening for
keywords within Web addresses. You can configure the router to log and report attempts to
access objectionable Internet sites.
Security
The FWG114P Wireless Firewall/Print Server is equipped with several features designed to
maintain security, as described in this section.
• 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 PCs on the LAN.
• Port Forwarding with NAT: Although NAT prevents Internet locations from directly accessing
the PCs on the LAN, the router allows you to direct incoming traffic to specific PCs based on
the service port number of the incoming request, or to one designated “DNS” host computer.
You can specify forwarding of single ports or ranges of ports.

2-4 Introduction
December 2003, M-10177-01
Autosensing Ethernet Connections with Auto Uplink
With its internal 8-port 10/100 switch, the FWG114P can connect to either a 10 Mbps standard
Ethernet network or a 100 Mbps Fast Ethernet network. Both the LAN and WAN interfaces are
autosensing and capable of full-duplex or half-duplex operation.
The router incorporates Auto UplinkTM technology. Each Ethernet port will automatically sense
whether the Ethernet cable plugged into the port should have a ‘normal’ connection such as to a
computer or an ‘uplink’ connection such as 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 cable to make the right connection.
Extensive Protocol Support
The FWG114P Wireless Firewall/Print Server supports the Transmission Control Protocol/Internet
Protocol (TCP/IP) and Routing Information Protocol (RIP). For further information about TCP/IP,
refer to Appendix B, “Network, Routing, and Firewall Basics.”
• The Ability to Enable or Disable IP Address Sharing by NAT. The FWG114P allows several
networked PCs to share an Internet account using only a single IP address, which may 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. This feature can also
be turned off completely for using the FWG114P in settings where you want to manage the IP
address scheme of your organization.
• Automatic Configuration of Attached PCs by DHCP: The FWG114P Wireless Firewall/Print
Server 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 router provides
its own address as a DNS server to the attached PCs. The router 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. This feature eliminates the need to
run a login program such as Entersys or WinPOET on your computer.
• PPTP login support for European ISPs, BigPond login for Telstra cable in Australia.
