Introduction

•

Automatic Configuration of Attached PCs by DHCP

The WGR614 router dynamically assigns network configuration information, including

IP, gateway, 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 router provides its own

address as a DNS server to the attached PCs. The router obtains actual DNS addresses from

the ISP during connection setup and forwards DNS requests from the LAN.

•

PPP over Ethernet (PPPoE)

PPPoE is a protocol for connecting remote hosts to the Internet over a DSL connection by

simulating a dial-up connection. This feature eliminates the need to run a login program such

as Entersys or WinPOET on your PC.

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 WGR614 router Smart Wizard automatically senses the type of Internet connection,

asking you only for the information required for your type of ISP account.
