Reference Manual for the MR814 v3 Cable/DSL Wireless Router

Introduction

802.11b Standards-based Wireless Networking
The MR814 v3 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.
•
WPA-PSK support. Support for Wi-Fi Protected Access (WPA) data encryption which
provides strong data encryption and authentication based on a pre-shared key.
•
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 MR814 v3 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 MR814 v3 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 MR814 v3 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 MR814 v3 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 MR814 v3 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 Uplink
TM
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 MR814 v3 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 MR814 v3 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.

•
Automatic Configuration of Attached PCs by DHCP
The MR814 v3 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 MR814 v3 Cable/DSL Wireless Router within minutes
after connecting it to the network. The following features simplify installation and management
tasks:
•
Smart Wizard Configuration Assistant
A user-friendly Smart Wizard configuration assistant that automatically connects you to the
router, detects the type of Internet connection you have, and guides you through enabling your
wireless network.
•
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 Wizard
The MR814 v3 router automatically senses the type of Internet connection, asking you only
for the information required for your type of ISP account.
•
Visual monitoring
The MR814 v3 router’s front panel LEDs provide an easy way to monitor its status and
activity.
