Introducing the ZyXEL Device
This chapter introduces the main applications and features of the ZyXEL Device. It also
introduces the ways you can manage the ZyXEL Device.
1.1
Overview
The P-660HN-FxZ series are ADSL2+ routers. By integrating DSL and NAT, you are
provided with ease of installation and high-speed, shared Internet access. The P-660HN-FxZ
is also a complete security solution with a robust firewall and content filtering.
Please refer to the following description of the product name format.
“H” denotes an integrated 4-port hub (switch).
“N” denotes 802.11n draft 2.0. The “N” models support 802.11n wireless connection
mode.
Models ending in “1”, for example P-660HN-F1, denote a device that works over the
analog telephone system, POTS (Plain Old Telephone Service). Models ending in “3”
denote a device that works over ISDN (Integrated Services Digital Network) or T-ISDN
(UR-2).

Command Line Interface. Line commands are mostly used for troubleshooting by service
engineers.
FTP for firmware upgrades and configuration backup/restore.
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.
TR-069. This is an auto-configuration server used to remotely configure your device.
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).

ZyXEL Device’s Router Features
You can also configure firewall and content filtering 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 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 QoS 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.
