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 feaure to block access to specific web sites or Internet 
applications such as MSN or Yahoo Messanger. 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’ excessive file downloading.
1.4.2  Using the WPS/WLAN Button
By default, the wireless network is turned off on the ZyXEL Device. To turn it on, 
simply press the WPS/WLAN button on top of the device for 1 second. Once the 
WPS/WLAN LED turns green, the wireless network is active.
You can also use the WPS/WLAN button to quickly set up a secure wireless 
connection between the ZyXEL Device and a WPS-compatible client by adding one 
device at a time.
To activate WPS:
1
Make sure the POWER LED is on and not blinking.
2
Press the WPS/WLAN button for five to ten seconds and release it.
3
Press the WPS button on another WPS-enabled device within range of the ZyXEL 
Device. The WPS/WLAN LED should flash while the ZyXEL Device sets up a WPS 
connection with the other wireless device. 
4
Once the connection is successfully made, the WPS/WLAN LED shines green.
