Setting a Schedule to Block or Allow Traffic
If you defined an outbound or inbound rule to use a schedule, you can set up a schedule for when

To invoke rules and block keywords or Internet domains based on a schedule:
1.
Select
Security
from the main menu and
Schedule
from the sub-menu. The
Schedule 1
screen
will display.
2.
Check the radio button for All Days or Specific Days. If you chose Specific Days, check the
radio button for each day you want the schedule to be in effect.
3.
Check the radio button to schedule the time of day: All Day, or Specific Times. If you chose
Specific Times, enter the Start Time and End Time fields (Hour, Minute, AM/PM), which will
limit access during certain times for the selected days.

Click
