ZyXEL Communications 5 Series User Manual

Chapter 1 Getting to Know Your ZyWALL

ZyWALL 5/35/70 Series User’s Guide

Use any of the following methods to manage the ZyWALL.

• Web Configurator. This is recommended for everyday management of the ZyWALL 

using a (supported) web browser.

• Command Line Interface. Line commands are mostly used for troubleshooting by service 

engineers. See the Command Reference Guide for more information about the CLI.

• SMT. System Management Terminal is a text-based configuration menu that you can use 

to configure your device.

• FTP for firmware upgrades and configuration backup/restore.

• SNMP. The device can be monitored by an SNMP manager. See the SNMP chapter in this 

User’s Guide.

• Vantage CNM (Centralized Network Management). The device can be remotely managed 

using a Vantage CNM server.

Do the following things regularly to make the ZyWALL more secure and to manage the 
ZyWALL 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 ZyWALL to its factory 
default settings. If you backed up an earlier configuration file, you would not have to 
totally re-configure the ZyWALL. You could simply restore your last configuration.
