rules

you
to
prevent
users
on
your

from
accessing
particular
websites
by

meet
your

these
are
user-defined

filter
rules

Keywords
Filtering:
Allows
blocking
by
specific
keywords
within
a
particular
URL
rather
than
having
to
specify
a
complete
URL
(e.g.
to
block
any
image
called
“advertisement.gif”).
When
enabled,
your
specified
keywords
list
will
be
checked
to
see
if
any
keywords
are
present
in
URLs
accessed
to
determine
if
the
connection
attempt
should
be
blocked.
Please
note
that
the
URL
filter
blocks
web
browser
(HTTP)
connection
attempts
using
port
80
only.
For
example
,
if
the
URL
is
http://www.abc.com/abcde.html,
it
will
be
dropped
if
the
keyword
“abcde”
occurs
in
the
URL.
Domains
Filtering:
This
function
checks
the
whole
URL
(not
the
IP
address)
in
URLs
accessed
against
your
list
of
domains
to
block
or
allow.
If
it
is
matched,
the
URL
request
will
be
sent
(Trusted)
or
dropped
(Forbidden). For
this
function
to
be
activated,
both
check-boxes
must
be
checked. Here
is
the
checking
procedure:
1.
The
router
checks
the
domain
in
the
URL
to
determine
if
it
is
in
the
trusted
list.
If
it
is,
the
connection
attempt
is
sent
to
correct
the
remote
web
server.
2.
If
not,
the
router
checks
if
the
domain
is
listed
in
the
forbidden
list.
If
it
is,
then
the connection
attempt
will
be
dropped.
