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 firewall and filtering feature 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 the filtering feature to block access to specific web sites or Internet applications such as MSN or
Yahoo Messenger. You can also configure IP/MAC filtering rules for incoming or outgoing traffic.
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.
1.5 Wireless Access
The ZyXEL Device is a wireless Access Point (AP) for wireless clients, such as notebook computers
or PDAs and iPads. It allows them to connect to the Internet without having to rely on inconvenient
Ethernet cables.
