Chapter 1 Introducing the ZyXEL Device

Use content filtering to block access to specific web sites, with URL’s containing keywords that you specify. You can define time periods and days during which content filtering is enabled and include or exclude particular computers on your network from content filtering. For example, you could block access to certain web sites for the kids.

Use bandwidth management to efficiently manage traffic on your network by giving priority to certain types of traffic and/or to particular computers. For example, you could make sure that the ZyXEL Device gives voice over Internet calls high priority, and/or limit bandwidth devoted to the boss’s excessive file downloading.

1.2 Ways to Manage the ZyXEL Device

Use any of the following methods to manage the ZyXEL Device.

Web Configurator. This is recommended for everyday management of the ZyXEL Device using a web browser.

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

FTP for firmware upgrades and configuration backup/restore (Chapter 18 on page 211)

SNMP. The device can be monitored by an SNMP manager. See the SNMP chapter in this User’s Guide.

SPTGEN. SPTGEN is a text configuration file that allows you to configure the device by uploading an SPTGEN file. This is especially convenient if you need to configure many devices of the same type.

1.3Good Habits for Managing the ZyXEL Device

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