Chapter 2
Introduction
This chapter describes the features of the NETGEAR ProSafe Wireless 802.11g Firewall/Print
Server Model FWG114P v2.
Key Features of the FWG114P v2
The ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P v2, 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 v2 provides highly reliable Internet access.
The FWG114P v2 is a complete security solution that protects your network from attacks and
intrusions and enables secure communications using Virtual Private Networks (VPNs). Unlike
simple Internet sharing routers that rely on Network Address Translation (NAT) for security, the
FWG114P v2 uses Stateful Packet Inspection for Denial of Service attack (DoS) attack protection
and intrusion detection. The FWG114P v2 allows Internet access for up to 253 users. It provides
multiple Web content filtering options, plus browsing activity reporting and instant alerts via
e-mail. Parents or 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.
With minimum setup, you can install and use the router within minutes. The FWG114P v2
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.
• Supports two VPN tunnels, Content Filtering, and Site Blocking Security.
• Wireless Multimedia (WMM) support.
• Built-in 4-port 10/100 Mbps Switch and USB 2.0 Printer Port.
• Ethernet and Serial ports for connection to a WAN device, such as a broadband modem.
• Extensive Protocol Support.
• Login capability.
• Front panel LEDs for easy monitoring of status and activity.

• Wireless network name broadcast can be turned off so that only devices that have the network
name (SSID) can connect.
Virtual Private Networking
The FWG114P v2 W ireless Firewall/Print Server p rovides a secure encrypted connectio n between
your local network and remote networks or clients. Its VPN features include:
• Support for up to 2 simultaneous VPN connections.
• Support for industry standard VPN protocols.
The ProSafe Wireless 802.11g Firewall/Print Server Model FWG114P v2 supports standard
keying methods (Manual or IKE), standard authentication methods (MD5 and SHA-1), and
standard encryption methods (DES, 3DES). It is compatible with many other VPN products.
• Support for up to 168 bit encryption (3DES) for maximum security.
• Support for VPN Main Mode, Aggressive mode, or Manual Keying.
• Support for Fully Qualified Domain Name (FQDN) configuration when the Dynamic DNS
feature is enabled with one of the supported service providers.
Wireless Multimedia (WMM) Support
WMM is a subset of the 802.11e standard. WMM allows wireless traffic to have a range of
priorities, depending on the kind of data. Time-dependent information such as video or audio will
have a higher priority than normal traffic. For WMM to function correctly, wireless clients must
also support WMM.
A Powerful, True Firewall with Content Filtering
Unlike simple Internet sharing NAT routers, the FWG114P v2 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 v2 will log security events, such as blocked incoming traffic, port scans,
attacks, and administrator logins. You can configure the router to e-mail the log to you at
specified intervals. You can also configure the router to send immediate alert messages to your
e-mail address or e-mail pager whenever a significant event occurs.
• With its content filtering feature, the FWG114P v2 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 v2 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.
Autosensing Ethernet Connections with Auto Uplink
With its internal 8-port 10/100 switch, the FWG11 4P v2 can conn ect to eith er 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.
TM
The router incorporates Auto Uplink
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 v2 Wireless Firewall/Print Server supports the Transmission Control Protocol/
Internet Protocol (TCP/IP) and Routing Information Protocol (RIP).
• The ability to enable or disable IP address sharing by NAT.
The FWG114P v2 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 v2 in
settings where you want to manage the IP address scheme of your organization.
• Automatic configuration of attached PCs by DHCP.
The FWG114P v2 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.
• Classical IP (RFC 1577).
Some Internet service providers, in Europe for example, use Classical IP in their ADSL
services. In such cases, the firewall is able to use the Classical IP address from the ISP.
