1.3 Good Habits for Managing the N4100
Do the following things regularly to make the N4100 more secure and to manage
the N4100 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
N4100 to its factory default settings. If you backed up an earlier configuration
file, you would not have to totally re-configure the N4100. You could simply
restore your last configuration.
1.4 Applications for the N4100
Here are some example uses for which the N4100 is well suited.
1.4.1 Internet Access
With a broadband modem or router (A), the N4100 allows the attached computers
to enjoy high speed Internet access. Computers can connect to the ZyXEL
Device's LAN ports (or wirelessly).
In public areas, such as a hotel or coffee shop, the N4100 provides high speed
Internet access to subscribers with account billing and authentication, which can
be done using a statement printer (B) and local subscriber database.
You can also configure filtering on the N4100 for secure Internet access. Use
filtering to block access to specific IP addresses or web sites. For example, you
could block subscriber access to pornographic or gambling web sites (2).
