Description
Date/Time
From the drop-down list, select the local time zone in which the VPN firewall
operates. The correct time zone is required in order for scheduling to work
correctly. The VPN firewall includes a real-time clock (RTC), which it uses for
scheduling.
Automatically Adjust for
Daylight Savings Time
If daylight savings time is supported in your region, select the Automatically
Adjust for Daylight Savings Time check box.
Select NTP Mode
In all three NTP modes, the VPN firewall functions both as a client and a server.
The VPN firewall synchronizes its clock with the specified NTP server or servers
and provides time service to clients. From the drop-down list, select the NTP
mode:
• Authorative Mode. The VPN firewall synchronizes its clock with the specified
NTP server or servers on the Internet. If external servers are unreachable, the
VPN firewall’s RTC provides time service to clients. In authorative mode, you
can enter a stratum value and set the date and time manually.
• Sync to NTP Servers on Internet. The VPN firewall synchronizes its clock
with the specified NTP server or servers on the Internet. If external servers are
unreachable, the VPN firewall does not use it’s RTC.
• Sync to NTP Servers on VPN. The VPN firewall synchronizes its clock with
the specified NTP server on the VPN. If the server is unreachable, the VPN
firewall does not use it’s RTC. You need to select a VPN policy that enables
the VPN firewall to contact the NTP server on the VPN.
Select Stratum
In authorative mode, enter a stratum value, which indicates
the distance from a reference clock. The default value is 10,
which specifies an unsynchronized local clock and causes
NTP to use the VPN firewall’s RTC when the specified NTP
server is not available.
Set date and time
manually
This is an optional setting that is available in authorative
mode. Select the check box to unmask the time (hour,
minute, second), Day, Month, and Year fields. Enter the
date and time.
Select VPN Policy
When the VPN firewall is configured to synchronize to an
NTP server on the VPN, select the VPN policy from the
drop-down list. For information about configuring VPN
policies, see Configure VPN Policies on page 165.
