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 Setup 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. Then you can apply them to your Internet Access or VPN
and Remote Access >> LAN-to-LAN settings.
To add a schedule, please click any index, say Index No. 1. The detailed settings of the call
schedule with index 1 are shown below.
