Reference Manual for the 108 Mbps Wireless Firewall Router WGT624

•IP Address Sharing by NAT

The WGT624 wireless router 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 NAT, allows the use of an inexpensive single-user ISP account.

•Automatic Configuration of Attached PCs by DHCP

The WGT624 wireless 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.

Easy Installation and Management

You can install, configure, and operate the 108 Mbps Wireless Firewall Router WGT624 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 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 WGT624 wireless router Smart Wizard automatically senses the type of Internet connection, asking you only for the information required for your type of ISP account.

•Firmware Auto-Update

The WGT624 wireless router automatically checks the Internet to see if a newer version of firmware is available. If so, it asks you if you want to install the upgrade. This lets you take advantage of product enhancements for your WGT624 as soon as they become available.
