Introduction 1-1
Chapter 1
Introduction
This chapter describes the features of the NETGEAR Model MR814 Wireless Router.
About the Router
The Model MR814 Wireless Router provides continuous, high-speed 11 Mbps access between
your wireless and Ethernet devices. Also, the Model MR814 router enables your entire network to
share an Internet connection through a cable modem or DSL modem that otherwise is used by a
single PC. With minimum setup, you can install and use the router within minutes.
The Model MR814 router provides multiple Web content filtering options, plus e-mail browsing
activity reporting and instant alerts. 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. Network Address
Translation (NAT) protects you from hackers.
Key Features
The Model MR814 router provides the following features:
• 802.11b Standards-based wireless networking
• Easy, web-based setup for installation and management
•Security
• Ethernet connection to a wide area network (WAN) device, such as a cable modem or DSL
modem
• Extensive Internet Protocol Support

Reference Manual for the Model MR814 Wireless Router
1-2 Introduction
These features are discussed below
802.11b Standards-based Wireless Networking
The Model MR814 router includes an 802.11b-compliant wireless access point, providing
continuous, high-speed 11 Mbps access between your wireless and Ethernet devices. The access
point provides:
• 802.11b Standards-based wireless networking at up to 11 Mbps
• 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.
Content Filtering
With its content filtering features, the Model MR814 router prevents objectionable content from
reaching your PCs. Its content filtering features include:
• Content filtering by domain or keyword
The Model MR814 router uses content filtering to enforce your network’s Internet access
policies. The router allows you to control access to Internet content by screening for keywords
within Website names or newsgroup names.
• Logging of inappropriate use
You can configure the Model MR814 router to log access to Web sites and to e-mail the log to
you. You can also configure the router to send an immediate alert e-mail message to you
whenever a local user attempts to access a blocked Web site.
Security
The Model MR814 router is equipped with several features designed to maintain security, as
described in this section.
• PCs Hidden by NAT
Network address translation (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.

Reference Manual for the Model MR814 Wireless Router
Introduction 1-3
• 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.
• Encryption of the Wireless Link
For security against eavesdropping of the wirelesssignal, the router supports Wired Equivalent
Privacy (WEP) data encryption with Shared Key authentication. You can also restrict access to
the wireless network by MAC address.
• Additional security features include the following:
– Parental control of web browsing and newsgroup access using Web Address (URL)
keyword blocking
– Auditing and e-mail reporting of web browsing activities
– Blocking can be scheduled by day and time
– Network Address Translation (NAT) hides local PCs from the Internet
– Incoming port forwarding and DMZ for hosting specific Internet services without
sacrificing unauthorized access to your private network.
Autosensing 10/100 Ethernet
With its internal, 4-port 10/100 switch, the Model MR814 router can connect to either a 10 Mbps
standard Ethernet network or a 100 Mbps Fast Ethernet network. The local LAN interface is
autosensing and is capable of full-duplex or half-duplex operation.
Also, there is a built in 4-port 10/100 Mbps Switch which provides the following features:
• Allows LAN connections at 10 megabits per second (Mbps) or 100 Mbps
• Autosensing for Ethernet (10BASE-T) or Fast Ethernet (100BASE-Tx) transmissions
• Half-duplex or full-duplex operation

Reference Manual for the Model MR814 Wireless Router
1-4 Introduction
Extensive Internet Protocol Support
The Model MR814 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 and Routing Basics.”
• IP Address Sharing by NAT
The Model MR814 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 Network Address Translation (NAT), allows
the use of an inexpensive single-user ISP account.
• Automatic Configuration of Attached PCs by DHCP
The Model MR814 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)
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.
–IProuting
– Network Address Translation (NAT) for operation with a single static or dynamic IP
address
– Dynamic Host Configuration Protocol (DHCP) server for dynamically assigning
network configuration information to PCs on the LAN
– DHCP client for dynamically obtaining configuration information from the Internet
Service Provider (ISP)
– DNS Proxy for simplified configuration
– PPP over Ethernet (PPPoE) support
