Setting a Schedule for Firewall Rules
If you defined an outbound or inbound rule to use a schedule, you can set up a schedule for when
blocking occurs or when access is restricted. The firewall allows you to specify when blocking
will be enforced by configuring one of the Schedules—Schedule 1, Schedule 2 or Schedule 3.
The ProSafe DGFV338 uses the Network Time Protocol (NTP) to obtain the current time and date
from one of several Network Time Servers on the Internet.
To invoke rules and block keywords or Internet domains based on a schedule:
1.
Select
Security
from the main menu, and
Schedule
from the submenu. The Schedule 1 screen
will display.
2.
Schedule days by selecting either the
All Days
radio button or the
Specific Days
radio button.
If you selected
Specific Days,
specify which days.
