3.5.2 Schedule
The Vigor router has a built-in real time clock which can update itself manually or
automatically by means of Network Time Protocols (NTP). As a result, you can not only
schedule the router to dialup to the Internet at a specified time, but also restrict Internet access
to certain hours so that users can connect to the Internet only during certain hours, say,
business hours. The schedule is also applicable to other functions.
You have to set your time before set schedule. In
System Maintenance>>
Time and Date
menu, press
Inquire Time
button to set the Vigor router’s clock to current time of your PC.
The clock will reset once if you power down or reset the router. There is another way to set up
time. You can inquiry an NTP server (a time server) on the Internet to synchronize the router’s
clock. This method can only be applied when the WAN connection has been built up.
You can set up to 15 schedules. To add a schedule profile, please click
Add
.

3.5.5 UPnP Configuration
The
UPnP
(Universal Plug and Play) protocol is supported to bring to network connected
devices the ease of installation and configuration which is already available for directly
connected PC peripherals with the existing Windows 'Plug and Play' system. For NAT routers,
the major feature of UPnP on the router is “NAT Traversal”. This enables applications inside
the firewall to automatically open the ports that they need to pass through a router. It is more
reliable than requiring a router to work out by itself which ports need to be opened. Further,
the user does not have to manually set up port mappings or a DMZ.
UPnP is available on
Windows XP
and the router provide the associated support for MSN Messenger to allow full
use of the voice, video and messaging features.
Enable UPNP
Enable UPnP function. You have to type the download and
upload speed.
After setting
Enable UPNP Service
setting, an icon of
IP Broadband Connection on Router
on Windows XP/Network Connections will appear. The connection status and control status
will be able to be activated. The NAT Traversal of UPnP enables the multimedia features of
your applications to operate. This has to manually set up port mappings or use other similar
methods. The screenshots below show examples of this facility.
The UPnP facility on the router enables UPnP aware applications such as MSN Messenger to
discover what are behind a NAT router. The application will also learn the external IP address
and configure port mappings on the router. Subsequently, such a facility forwards packets from
the external ports of the router to the internal ports used by the application.

The reminder as regards concern about Firewall and UPnP
Can't work with Firewall Software
Enabling firewall applications on your PC may cause the UPnP function not working
properly. This is because these applications will block the accessing ability of some network
ports.
Security Considerations
Activating the UPnP function on your network may incur some security threats. You should
consider carefully these risks before activating the UPnP function.
¾
Some Microsoft operating systems have found out the UPnP weaknesses and hence
you need to ensure that you have applied the latest service packs and patches.
¾
Non-privileged users can control some router functions, including removing and
adding port mappings.
The UPnP function dynamically adds port mappings on behalf of some UPnP-aware
applications. When the applications terminate abnormally, these mappings may not be
removed.
3.5.6 Wake On LAN
A PC client on LAN can be woken up by the router it connects. When a user wants to wake up
a specified PC through the router, he/she must type correct MAC address of the specified PC
on this web page of
Wake On LAN
of this router.
In addition, such PC must have installed a network card supporting WOL function. By the
way, WOL function must be set as “Enable” on the BIOS setting.
