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.
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.
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.

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.
