Setting a Schedule to Block or Allow Specific Traffic
If you enabled Content Filtering in the Security/Block Sites menu, or if you defined an outbound
rule to use a schedule, you can set up a schedule for when blocking occurs or when acc ess is
restricted. The firewall allows you to specify when blocking will be enforced by configuring the
Schedule 1, Schedule 2 or Schedule 3 screens.
The ProSafe DGFV338 uses the Network Time Protocol (NTP) to obtain the current time and date
from one of several Networ k Time Servers on the Internet.
To invo ke rules and block keywords or Interne t domains based on a sche dule:
1. Select Security from the main menu, and Schedule from the submenu. The Schedule 1 screen
will display.
2. Schedule which Days you want by selecting either the All Days radio button or the Specific
Days radio button. If you se lected Specific Days, specify which days.
3. Select the time of day radio box: either All Day if you want to limit access completely for the
selected days; or select a Specific Times to limit access during the selected days.
If you selected Specific Times, enter the Start Time and End Time for this schedule in the
appropriate fields.
4. Click Apply to save your settings.
