Setting the Inactivity
Timeout
The Administrator Inactivity Timeout Setting allows you to extend or
reduce the period of time before the administrator is automatically
logged out of the Web interface. The Firewall is pre-configured to logout
the administrator after 5 minutes of inactivity.
Setting the Time
From the General screen, select Set Tim e. A window similar to that in
Figure 23 displays.
Figure 23 Set Time Window
Time Zone
Select your time zone from the drop-down list box at the top of the
screen. If you cannot find your time zone in the list, you should set this to
the one with the same offset from GMT as is used at your location.
Use NTP (Network Time Protocol) to set time automatically
Check this box to allow the Firewall to synchronize its time using an
Network Time Protocol (NTP) server every hour. For example, if you
started the Firewall at 2:30, the clock will synchronize every hour at the
half hour—3:30, 4:30 etc.
To set the time automatically you need a connection to the Internet.
3Com recommends that initially you set the time manually even if you
have selected this option.
See
Manual Time Set below to set the time manually.
