The Router filters all traffic from domains that have been blocked using
the URL filter. If you need to access an external mail server, FTP server or
other named device outside your network, you must list it in one of the
allow fields.
You can filter up to 30 keywords and URLs.
Computers that should not be subject to URL filtering can be excluded by
ticking the Bypass URL Filter checkbox in the PC Privileges setup screen.
See
“PC Privileges” on page 77 .
Content Filter You can subscribe to the 3Com Content Filter Service, which enables you
to block or allow the URLs 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
(3CSBCFS).
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. Refer to
“Allow List” on page 81 for
more information.
