• 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 IP filtering on the ZyXEL Device for secure Internet access. When the
IP filter is on, all incoming traffic from the Internet to your network is blocked by default
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.
