Getting to Know Your ZyXEL

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

1.1 Overview

This ZyXEL Device is a secure router with a 4-port switch and print server.

Typical uses for the ZyXEL Device are as a print server or as a print server and router
combined. When you use it as a print server, you don’t have to make any configuration
changes to your existing network. When you use it as a print server and router combined, you
can take advantage of a host of features such as firewall, content filtering and bandwidth
management.

P-335 Plus User’s Guide

CHAPTER 1

Device

See Appendix A on page 177 for a complete list of features you can configure on your ZyXEL
Device.

1.1.1 Print Server

The ZyXEL Device’s print server allows your network’s computers to share a printer. Simply
connect a USB printer to the USB port on the ZyXEL Device. To disable routing functions,
put the PR switch to the P position.

P-335 Plus User’s Guide

1.1.2 Print Server and Router Combined

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. See the Quick Start Guide for instructions on
hardware connections.

Figure 2 ZyXEL Device as a Print Server and Router Combined

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 Good Habits for Managing Your ZyXEL Device

Here are some things you should do regularly.

• Change your password.

• Back up your configuration (and make sure you know how to reload it).

• Check www.zyxel.com for firmware upgrades.
