manual abstract
The MR814v2 router provides connection for multiple personal computers (PCs) to the Internet through an external broadband access device (such as a cable modem or DSL modem) that is normally intended for use by a single PC. Audience This reference manual assumes that the reader has basic to intermediate computer and Internet skills. However, basic computer network, Internet, firewall, and VPN technologies tutorial information is provided in the Appendices and on the Netgear website. Typographical Conventions This guide uses the following typographical conventions: Special Message Formats This guide uses the following formats to highlight special messages: Chapter 1 Introduction This chapter describes the features of the NETGEAR MR814v2 Cable/DSL Wireless Router. Key Features of the Router The MR814v2 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 MR814v2 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 MR814v2 router provides the following features: •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 wide area network (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 802.11b Standards-based Wireless Networking The MR814v2 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. •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 MR814v2 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 MR814v2 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 MR814v2 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 MR814v2 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 MR814v2 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...
