Problems with Date and Time
The E-Mail menu in the Content Filtering section displays the current date and time of day. The
ProSafe DGFV338 uses the Network Time Protocol (NTP) to obtain the current time from one of
several Network Time Servers on the Internet. Each entry in the log is stamped with the date and
time of day. Problems with the date and time function can include:
•
Date shown is January 1, 2000. Cause: The firewall has not yet successfully reached a
Network Time Server. Check that your Internet access settings are configured correctly. If you
have just completed configuring the firewall, wait at least five minutes and check the date and
time again.
•
Time is off by one hour. Cause: The firewall does not automatically sense Daylight Savings
Time. In the E-Mail menu, check or uncheck the box marked “Adjust for Daylight Savings
Time”.
Using the Diagnostics Utilities
You can perform diagnostics such as pinging an IP address, perform a DNS lookup, display the
routing table, reboot the firewall, and capture packets.
Note:
For normal operation, diagnostics are not required
