  • Page 17: About The Modem Router

    This chapter describes the features of the NETGEAR 54 Mbps ADSL Modem Wireless Router Model DG834G. The ADSL Modem Wireless Router is a combination of a built-in ADSL modem, modem router, 4-port switch, and firewall which enables your entire network to safely share an Internet connection that otherwise would be used by a single computer.

  • Page 18: Key Features, A Powerful, True Firewall

    These features are discussed below. A Powerful, True Firewall Unlike simple Internet sharing NAT routers, the DG834G 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 Denial of Service (DoS) attacks such as Ping of Death, SYN Flood, LAND Attack and IP Spoofing.

  • Page 19: Standards-based Wireless Networking, Easy Installation And Management

    • Wireless access can be restricted by MAC address Easy Installation and Management You can install, configure, and operate the DG834G v3 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 modem router from almost any type of personal computer, such as Windows, Macintosh, or Linux.

  • Page 20: Protocol Support

    The Ability to Enable or Disable IP Address Sharing by NAT The DG834G v3 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).

  • Page 21: Virtual Private Networking (vpn), Auto Sensing And Auto Uplinkā„¢ Lan Ethernet Connections

    Auto Sensing and Auto Uplink™ LAN Ethernet Connections With its internal 4-port 10/100 switch, the DG834G v3 can connect to either a 10 Mbps standard Ethernet network or a 100 Mbps Fast Ethernet network. The local LAN ports are autosensing and capable of full-duplex or half-duplex operation.

  • Page 22: Content Filtering, Wi-fi Multimedia (wmm) Quality Of Service (qos), Wmm Power Save

    Content Filtering With its content filtering feature, the DG834G v3 prevents objectionable content from reaching your PCs.
