The DG632 modem router is a combination of a built-in ADSL modem, router, and firewall which enables your network to safely share an Internet connection that otherwise is used by a single computer. Note: If you are unfamiliar with networking and routing, refer to Appendix B, "Network and Routing Basics" to become more familiar with the terms and procedures used in this manual. About the Modem The DG632 ADSL Modem Router provides continuous, high-speed 10/100 Ethernet access between your Ethernet devices. The DG632 modem router enables your network to share an Internet connection through the built-in ADSL modem that otherwise is used by a single computer. With minimum setup, you can install and use the modem within minutes. The included firewall and Network Address Translation (NAT) features protect you from hackers. Key Features The DG632 modem router provides the following features: · · · · · · · A powerful, true firewall Auto Sensing and Auto UplinkTM LAN Ethernet connections Extensive Internet protocol support Easy, Web-based setup for installation and management Direct connection to the Internet using the built-in ADSL modem USB connection to your computer eliminates the need for installing an Ethernet card Modem or Router Device Mode 2-1 Introduction Reference Manual for the Model DG632 ADSL Modem Router ­ ­ Modem Device Mode supports configuration of your Internet connection on your computer, and running software on your computer to log in to your ISP, if needed. Router Device Mode supports configuration of your Internet connection on your DG632 modem router, and can be configured to automatically log in to your ISP, if needed. These features are discussed below. Modem or Router Device Mode The DG632 modem router can be set to operate in either Modem Device Mode or Router Device Mode. Modem Device Mode When set to operate in Modem Device Mode, your computer must be configured for whatever settings your ISP requires. Also, if your ISP uses software to establish your Internet connection, the DHCP spoofing feature will eliminate the need to run that software. When DHCP spoofing is enabled, the modem obtains the actual Internet WAN IP address from the ISP during connection setup and forwards it to the attached computer. Router Device Mode In Router Device Mode, the DG632 supports configuration of the Transmission Control Protocol/ Internet Protocol (TCP/IP) parameters and login functions on the modem. The DG632 supports Transmission Control Protocol/Internet Protocol (TCP/IP) and Routing Information Protocol (RIP). Appendix B, "Network and Routing Basics" provides further information on TCP/IP. · Automatic Configuration of Attached PCs by DHCP The DG632 dynamically assigns network configuration information, including IP, modem, 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 provides its own address as a DNS server to the attached PCs. The modem obtains actual DNS addresses from the ISP during connection setup and forwards DNS requests from the LAN. Introduction · 2-2 Reference Manual for the Model DG632 ADSL Modem Router · Classical IP (RFC 1577) Some Internet service providers, in Europe for example, use Classical IP in their ADSL services. In such cases, the modem 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. · · A Powerful, True Firewall Unlike simple Internet sharing NAT routers, the DG632 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. 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 DG632 will log security events such as blocked incoming traffic, port scans, attacks, and administrator logins. · · · Auto Sensing and Auto UplinkTM LAN Ethernet Connections The DG632 can connect to either a 10 Mbps standard Ethernet network or a 100 Mbps Fast Ethernet network. The local LAN port is autosensing and capable of full-duplex or half-duplex operation. The modem incorporates Auto UplinkTM technology. The local Ethernet port will automatically sense whether the Ethernet cable plugged into the port should have a `normal' connection such as to a computer 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. Introduction 2-3 Reference Manual for the Model DG632 ADSL Modem Router Easy Installation and Management You can install, configure, and operate the DG632 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 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 modem automatically senses the type of Internet connection, asking you only for the information required for your type of ISP account. Diagnostic functions The modem incorporates built-in diagnostic functions such as Ping, and DNS lookup. These functions allow you to test Internet connectivity. Visual monitoring The modem's front panel LEDs provide an easy way to monitor its status and activity. Flash erasable programmable read-only memory (EPROM) for firmware upgrade · · · · 2-4 Introduction Reference Manual for the Model DG632 ADSL Modem Router What's In The Box?
