1.2.1 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.

1.3 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 port 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 feaure to block access to specific web sites or Internet
applications such as MSN or Yahoo Messanger. You can also configure IP/MAC
filtering rules for incoming or outgoing traffic.
