1.3 Good 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.

1.4 Applications for the ZyXEL Device

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

1.4.1 Internet Access

Your ZyXEL Device provides shared Internet access by connecting the DSL port to the DSL or
MODEM jack on a splitter or your telephone jack. Computers can connect to the ZyXEL Device's
LAN ports (or wirelessly).

You can also configure firewall and filtering feature on the ZyXEL Device for secure Internet access.
When the firewall is on, all incoming traffic from the Internet to your network is blocked unless it is
initiated from your network. This means that probes from the outside to your network are not
allowed, but you can safely browse the Internet and download files.
Use the filtering feature to block access to specific web sites or Internet applications such as MSN or
Yahoo Messenger. You can also configure IP/MAC filtering rules for incoming or outgoing traffic.
