Reference Manual for the Model DG824M Wireless ADSL Modem Gateway
1-4 Introduction
• DNS Proxy
When DHCP is enabled and no DNS addresses are specified, the gateway provides its own
address as a DNS server to the attached PCs. The gateway obtains actual DNS addresses from
the ISP during connection setup and forwards DNS requests from the LAN.
• 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 PC.
• PPP over ATM (PPPoA)
PPP over ATM is a protocol for connecting remote hosts to the Internet over an ADSL
connection by simulating a ATM connection.
•Dynamic DNS
Dynamic DNS services allow remote users to find your network using a domain name when
your IP address is not permanently assigned. The gateway contains a client that can connect to
many popular Dynamic DNS services to register your dynamic IP address.
Easy Installation and Management
You can install, configure, and operate the DG824M 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 gateway 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 gateway automatically senses the type of Internet connection, asking you only for the
information required for your type of ISP account.
• Remote management
The gateway allows you to login 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, and you can choose a nonstandard port number.
