Getting to Know Your ZyXEL

This chapter introduces the main features and applications of the ZyXEL Device.

1.1 Overview

The ZyXEL Device is a wireless secure router with a 4-port switch and 56K modem.

The ZyXEL Device is always used as a wireless broadband router with a WAN dial-up
connection. You can also deploy the ZyXEL Device as an access point (AP) or a WiFi WAN
router. When you use the ZyXEL Device as a WiFi WAN router, you access the Internet via a
wireless WAN connection and still take advantage of a host of features such as NAT, firewall,
content filtering and bandwidth management.

P-334WHD User’s Guide

CHAPTER 1

Device

See Appendix A on page 217 for a complete list of features.

1.2 Applications for the ZyXEL Device

Here are some examples of what you can do with your ZyXEL Device.

The ZyXEL Device supports three operating modes: Router, Access Point and WiFi WAN
Router.

1.2.1 Router Mode

The ZyXEL Device is in Router mode by default and functions as a normal (wireless) router.

1.2.1.1 Internet Access via a Broadband Connection

For Internet access, connect the WAN Ethernet port to your existing Internet access gateway
(company network, or your cable or DSL modem for example). Connect computers or servers
to the LAN ports for shared Internet access.

Wireless clients can move freely anywhere in the coverage area and use resources on the wired
network.

See the Quick Start Guide for instructions on hardware connections.

Chapter 1 Getting to Know Your ZyXEL Device 29

P-334WHD User’s Guide

Figure 1 Router Mode: Internet Access via a Broadband Connection

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 for
example.

Use content filtering to block access to web sites 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 bandwidth management 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 voice over Internet calls get enough bandwidth in your network, and/or limit bandwidth
devoted to the boss’s excessive file downloading.

1.2.1.2 Internet Access via a Dial-up Connection

Alternatively, the computers connected to the ZyXEL Device can share Internet access via the
built-in 56K modem. If both the broadband and dial-up WAN connections are set up, the
ZyXEL Device uses the dial-up connection (via the modem) as a backup. When the primary
broadband WAN connection is down, the ZyXEL Device changes to use the dial-up WAN
connection automatically.
