You can subscribe to the 3Com Content Filter Service, which enables you
to block or allow the URL of a number of pre-defined categories.
The Router comes with a 14-day free trial of the 3Com Content Filter
Service. To activate the 14-day free trial of the service, you must first
register your Router at www.3com.com. To continue using the service
after the trial period, you must purchase the Full 3Com Content Filter
Service(3CS8CFS).
URL Filtering rules supersede content filtering rules. If the 3Com Content
Filter is blocking certain Web sites that you want to allow, you can add
these sites to URL Filter's allow list.

Time Zone
Time Zone Screen

zone setting is used by the system clock when displaying the correct time
in the log files.
If you use Daylight saving tick the
Enable Day Light savings
box, and then
click

The Router reads the correct time from NTP servers on the Internet and
sets its system clock accordingly. The Daylight Savings option merely
advances the system clock by one hour. It does not cause the system
clock to be updated for daylight savings time automatically.
