• 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 DG834GV will log security events such as blocked incoming traffic, port scans, attacks, and administrator logins. You can configure the modem router to email the log to you at specified intervals. You can also configure the modem router to send immediate alert messages to your email address or email pager whenever a significant event occurs. 2-2 Introduction v1.0, September 2006 Reference Manual for the Integrated ADSL Modem and Wireless Router with Voice, Model 802.11 Standards-based Wireless Networking The Integrated ADSL Modem Wireless Router with Voice includes an 802.11g-compliant wireless access point, providing continuous, high-speed 10/100 Mbps access between your wireless and Ethernet devices. The access point provides: • 802.11g Standards-based wireless networking at up to 54 Mbps • Works with both 802.11g and 802.11b wireless devices • 64-bit and 128-bit WEP encryption security • WEP keys can be entered manually or generated by passphrase • Support for Wi-Fi Protected Access Pre-Shared Key (WPA-PSK) encryption and 802.1x authentication • Wireless access can be restricted by MAC address Easy Installation and Management You can install, configure, and operate the DG834GV 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. A user-friendly Setup Wizard is provided and online help documentation is built into the browser-based Web Management Interface. • Smart Wizard The firmware in the modem router automatically senses the type of Internet connection, asking you only for the information required for your type of ISP account. • Remote management The modem router allows you to log in to the Web management interface from a remote location via the Internet. For security, you can limit remote management access to a specified remote IP address or range of addresses, or you can choose a nonstandard port number. • Diagnostic functions The modem router incorporates built-in diagnostic functions such as Ping, DNS lookup, and remote reboot. These functions allow you to test Internet connectivity and reboot the modem router. You can use these diagnostic functions directly from the DG834GV when you are connected on the LAN or when you are connected over the Internet via the remote management function. Introduction 2-3 v1.0, September 2006 Reference Manual for the Integrated ADSL Modem and Wireless Router with Voice, Model • Visual monitoring The modem router’s front panel LEDs provide an easy way to monitor its status and activity. • Flash erasable programmable read-only memory (EPROM) for firmware upgrades. Protocol Support The DG834GV supports Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing Information Protocol (RIP). “Internet Networking and TCP/IP Addressing” in Appendix B provides further information on TCP/IP. • The Ability to Enable or Disable IP Address Sharing by NAT The DG834GV 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. This feature can also be turned off completely while using the DG834GV if you want to manage the IP address scheme yourself. • Automatic Configuration of Attached PCs by DHCP The DG834GV dynamically assigns network configuration information, including IP, modem router, 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 modem router provides its own address as a DNS server to the attached PCs. The modem router obtains actual DNS addresses from the ISP during connection setup and forwards DNS requests from the LAN. • Classical IP (RFC 1577) Some Internet service providers, in Europe for example, use Classical IP in their ADSL services. In such cases, the modem router is able to use the Classical IP address from the ISP. • PPP over Ethernet (PPPoE) PPP over Ethernet is a protocol for connecting remote hosts to the Internet over an ADSL connection by simulating a dial-up connection. This feature eliminates the need to run a login program such as EnterNet or WinPOET on your computer. • PPP over ATM (PPPoA) PPP over ATM is a protocol for connecting remote hosts to the Internet over an ADSL connection by simulating an ATM connection. 2-4 Introduction v1.0, September 2006 Reference Manu...
