ZyXEL Device’s Internet Access Application

You can also configure the firewall 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 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 
email high priority, and/or limit bandwidth devoted to the boss’s excessive file downloading.

By default, the wireless LAN (WLAN) is enabled on the ZyXEL Device. IEEE 802.11b/g/n compliant 
clients can wirelessly connect to the ZyXEL Device to access network resources. You can set up a 
wireless network with WPS (WiFi Protected Setup) or manually add a client to your wireless 
network.

Wireless Connection Application 

Use the built-in USB 2.0 port to share files via a USB memory stick or a USB hard drive (A). 
Alternatively, you can add a USB printer (B) and make it available on your local area network.
