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.

screen.
If you entered the admin password, it is highly recommended you change the default admin
password! Enter a new password between 1 and 30 characters, retype it to confirm and click
Apply
; alternatively click
Ignore
to proceed to the main menu if you do not want to change the
password now.
Note: If you do not change the password at least once, the following screen appears
every time you log in with the admin password.

Change Password at Login
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.
