TimeSlot1

~

these

are

user-defined

time

periods. You

may

specify

the

time

period

during

which

the

URL

filter

rules

apply,

i.e.

during

working

and

refer

to

Time

Schedule

section.

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.

3.

If

the

packet

does

not

match

either

of

the

above

two

items,

it

is

sent

to

the

remote

web

server.

4.

Please

note

that

the

completed

URL,

“www”

+

domain

name

should

be

specified.

For

example

to

block

traffic

to

www.google.com.au

,

enter

“

www.google

”

or

“

www.google.com

”

In

the

example

below,

the

URL

request

for

www.abc.com

will

be

sent

to

the

remote

web

server

because

it is

listed

in

the

trusted

list,

whilst

the

URL

request

for

www.google

or

www.google.com

will

be

dropped,

because

www.google

is

in

the

forbidden

list.

Example:

Andy

wishes

to

disable

all

WEB

traffic

except

for

ones

listed

in

the

trusted

domain,

which

would

prevent

Bobby

from

accessing

other

web

sites. Andy

selects

both

check

boxes

in

Domain

Filtering

and

thinks

that

this

will

stop

Bobby.

But

Bobby

knows

this

function,

Domain

Filtering

,

ONLY

disables

all

WEB

traffic

except

for

Trusted

Domain,

BUT

not

connections

using

IP

addresses.

In

this

situation,

the

Block

surfing

by

IP

address

function

can

be

handy

and

helpful

to

Andy.

Now,

Andy

can prevent

Bobby

from

accessing

sites,

both

by

IP

and

by

domain

name.

Restrict

URL

Features:

This

function

enhances

your

URL

rules.

²

Block

Java

Applet:

This

function

can

block

Web

content

that

includes

a

Java

Applet.

This

is

to

prevent

someone

who

wants

to

damage

your

system

via

standard

HTTP

protocol.

²

Block

surfing

by

IP

address:

This

prevents

someone

who

uses

the

IP

address

as

URL

from

skipping

the

Domains

Filtering

function.

This

is

only

Activate

if

Domain

Filtering

is

enabled.

P2P

Blocking

IM,

short

for

Instant

is

required

to

use

client

program

software

that

allows

users

to

communicate,

exchanging

text

message,

with

other

IM

users,

in

real

time,

over

the

Internet.

A

P2P

application,

known

as

Peer-to-Peer,

is

a

group

of

computer

users

who

share

files

to

specific

groups

of

people

across

the

Internet.

Both

Instant

Messaging

and

Peer-to-Peer

applications

make

communication

faster

and

easier,

but

your

network

can

become

increasingly

insecure

at

the

same

time.

This

router’s

IM

helps
