Chapter 1 
Introduction
This chapter describes the features of the NETGEAR Model WGR614 Cable/DSL Wireless 
Router.
Key Features of the Router
The Model WGR614 Cable/DSL Wireless Router with 4-port switch connects your local area 
network (
LAN) to the Internet through an external access device such as a cable modem or DSL 
modem.
The WGR614 router provides you with multiple Web content filtering options, plus browsing 
activity reporting and instant alerts -- both via e-mail. Parents and network administrators can 
establish restricted access policies based on time-of-day, Website addresses and address keywords, 
and share high-speed cable/DSL Internet access for up to 253 personal computers. In addition to 
the Network Address Translation (
NAT) feature, the built-in firewall protects you from hackers.
With minimum setup, you can install and use the router within minutes.
The WGR614 router provides the following features:
•802.11g wireless networking, with the ability to operate in 802.11g-only or 802.11b+g modes.
• 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 wide area network (WA N) 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.

802.11g Wireless Networking
The WGR614 router includes an 802.11g wireless access point, providing continuous, high-speed 
54 Mbps access between your wireless and Ethernet devices. The access point provides:
• 802.11g wireless networking at up to 54 Mbps.
• 802.11g wireless networking, with the ability to operate in 802.11g-only or 802.11b+g modes, 
providing backwards compatibility with 802.11b devices or dedicating the wireless network to 
the higher bandwidth 802.11g 54Mbps devices.
• 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.
A Powerful, True Firewall with Content Filtering
Unlike simple Internet sharing NAT routers, the WGR614 is a true firewall, using stateful packet 
inspection to defend against hacker attacks. Its firewall features include:
•Denial of Service (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 WGR614 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 WGR614 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 WGR614 router 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 “DMZ” 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 WGR614 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 
PC 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 WGR614 router 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, Firewall, and Basics.”
• IP Address Sharing by NAT 
The WGR614 router 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.

1-4Introduction
 
• Automatic Configuration of Attached PCs by DHCP 
The WGR614 router 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 PC.
Easy Installation and Management
You can install, configure, and operate the Model WGR614 Cable/DSL Wireless Router 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 router 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 WizardTM 
The WGR614 router Smart Wizard automatically senses the type of Internet connection, 
asking you only for the information required for your type of ISP account.
• Visual monitoring 
The WGR614 router’s front panel LEDs provide an easy way to monitor its status and activity.
Maintenance and Support
NETGEAR offers the following features to help you maximize your use of the WGR614 router:
• Flash memory for firmware upgrade
• Free technical support seven days a week, twenty-four hours a day
