PPPoE (RFC2516)

PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up connection. It allows your ISP to

use their existing network configuration with newer broadband technologies such as ADSL. The

PPPoE driver on the ZyXEL Device is transparent to the computers on the LAN, which see only

Ethernet and are not aware of PPPoE thus saving you from having to manage PPPoE clients on

individual computers. The ZyXEL Device also includes PPPoE idle time-out (the PPPoE connection

terminates after a period of no traffic that you configure) and PPPoE Dial-on-Demand (the PPPoE

connection is brought up only when an Internet access request is made).

Network Address Translation (NAT)

Network Address Translation (NAT) allows the translation of an Internet protocol address used

within one network (for example a private IP address used in a local network) to a different IP

address known within another network (for example a public IP address used on the Internet).

Dynamic DNS Support

With Dynamic DNS support, you can have a static hostname alias for a dynamic IP address,

allowing the host to be more easily accessible from various locations on the Internet. You must

register for this service with a Dynamic DNS service provider.

DHCP

DHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to obtain the

TCP/IP configuration at start-up from a centralized DHCP server. The ZyXEL Device has built-in

DHCP server capability enabled by default. It can assign IP addresses, an IP default gateway and

DNS servers to DHCP clients. The ZyXEL Device can now also act as a surrogate DHCP server

(DHCP Relay) where it relays IP address assignment from the actual real DHCP server to the clients.

IP Alias

IP Alias allows you to partition a physical network into logical networks over the same Ethernet

interface. The ZyXEL Device supports three logical LAN interfaces via its single physical Ethernet

interface with the ZyXEL Device itself as the gateway for each LAN network.

Housing

Your ZyXEL Device's compact and ventilated housing minimizes space requirements making it easy

to position anywhere in your busy office.

Introducing the Web Configurator

This chapter describes how to access and navigate the web configurator.

2.1

Web Configurator Overview

The web configurator is an HTML-based management interface that allows easy ZyXEL Device setup

and management via Internet browser. Use Internet Explorer 6.0 and later or Netscape Navigator

7.0 and later versions. The recommended screen resolution is 1024 by 768 pixels.

In order to use the web configurator you need to allow:

•

Web browser pop-up windows from your device. Web pop-up blocking is enabled by default in

Windows XP SP (Service Pack) 2.

•

JavaScripts (enabled by default).

•

Java permissions (enabled by default).

See the chapter on troubleshooting if you need to make sure these functions are allowed in Internet

Explorer.

2.2

Accessing the Web Configurator

1

Make sure your ZyXEL Device hardware is properly connected (refer to the Quick Start Guide).

2

Prepare your computer/computer network to connect to the ZyXEL Device (refer to the Quick Start

Guide).

3

Launch your web browser.

4

Type "192.168.1.1" as the URL.

Note: The management session automatically times out when the time period set in the

Administrator Inactivity Timer

field expires (default five minutes). Simply log

back into the ZyXEL Device if this happens to you.
