ZyXEL N4100 Guia Do Utilizador

Chapter 1 Introduction

N4100 User’s Guide

Do the following things regularly to make the N4100 more secure and to manage 
the N4100 more effectively.

• Change the password. Use a password that’s not easy to guess and that consists 

of different types of characters, such as numbers and letters.

• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). 

Restoring an earlier working configuration may be useful if the device becomes 

unstable or even crashes. If you forget your password, you will have to reset the 

N4100 to its factory default settings. If you backed up an earlier configuration 

file, you would not have to totally re-configure the N4100. You could simply 

restore your last configuration.

Here are some example uses for which the N4100 is well suited.

With a broadband modem or router (A), the N4100 allows the attached computers 
to enjoy high speed Internet access. Computers can connect to the ZyXEL 
Device's LAN ports (or wirelessly).

In public areas, such as a hotel or coffee shop, the N4100 provides high speed 
Internet access to subscribers with account billing and authentication, which can 
be done using a statement printer (B) and local subscriber database. 

You can also configure filtering on the N4100 for secure Internet access. Use 
filtering to block access to specific IP addresses or web sites. For example, you 
could block subscriber access to pornographic or gambling web sites (2).
