4.3.4.6 URL Filter

URL (Uniform Resource Locator – e.g. an address in the form of

http://www.yahoo.com

or

http://www.example.com

) filter rules allow you to prevent users on your network from

accessing particular websites from their URL. There are no pre-defined URL filter rules; you

can add filter rules to meet your requirements.

Active:

Select

Yes

from the drop down list box to enable or disable the URL Filter feature.

Always Block:

Select to always check URL filter rules (i.e. at all hours of the day).

Block from:

Specify the time period to check URL filter rules (e.g. during work hours).

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 is checked to see if any keywords are present in

URLs accessed to determine if the connection attempt should be blocked. Note that the URL

filter blocks web browser (HTTP) connection attempts using port 80 only.

For example, the URL

http://www.abc.com/abcde.html

would be dropped since the keyword

“abcde” occurs in the URL.

Domains Filtering:

Checks the domain name in URLs accessed against your list of

domains to block or allow. If it matches, the URL request is sent (Trusted) or dropped

(Forbidden). The checking procedure is:

1. Check the domain in the URL to determine if it is in the trusted list. If yes, the connection

attempt is sent to the remote web server.

2. If not, it is checked with the forbidden list. If present, the connection attempt is dropped.

3. If the packet matches neither of the above, it is sent to the remote web server.

4. Please note that only the domain is specified, not the full URL. For example to block

traffic to

www.sex.com

, enter “sex” or “sex.com” instead of “www.sex.com”. In the

example below, the URL request for

www.abc.com

is sent to the remote web server

because it is listed in the trusted list, while the URL request for

www.sex

or

www.sex.com

is dropped because sex.com is in the forbidden list.

4.3.5 QoS (Quality of Service)

Quality of Service Introduction

If you’ve ever found your ‘net’ speed has slowed to a crawl because another family

member is using a P2P file sharing program, you’ll understand why the Quality of

Service features in routers is such a breakthrough for home users and office users

.

QOS: Keeping Your Net Connection Fast and Responsive

Configurable by source IP address, destination IP address, protocol, and port, the Quality of

Service (QOS) gives you full control over which types of outgoing data traffic should be given

priority by the router, ensuring bandwidth-consumption data like gaming packets,

latency-sensitive application like voice, or even mission critical files, move through the router

at lightning speed, even under heavy load. You can throttle the speed at which different

types of outgoing data pass through the router. In addition, you can simply change the

priority of different types of upload data and let the router sort out the actual speeds.

QOS Setup

Please choose the

QOS

in the

Configuration

item of the left window as depicted below.

After clicking the QOS item, you can Add/Edit/Delete a QOS policy.

This page will show the

brief information for policies you have added or edited.

This page will also display the total

available (Non-assigned) bandwidth, in percentage, can be assigned.

Application

: A name that identifies an existing policy.

Time Schedule

: Scheduling your QOS policy to be applied.

Direction

: The traffic flow direction to be controlled by the QOS policy.

There are two settings to be provided in the Router:

~

LAN to WAN:

You want to control the traffic flow from the local network to the outside

world.

E.g., you have a FTP server inside the local network and you want to have a limited

traffic rate controlled by the QOS policy. So, you need to add a policy with LAN to WAN

direction setting.

~

LAN to WAN

: Control Traffic flow from the WAN to LAN.

The connection maybe either

issued from LAN to WAN or WAN to LAN.)

Assigned Bandwidth Ratio

: This field shows the assigned bandwidth ratio in

percentage for a QOS policy.

If WAN connection to internet is established, the estimated

transfer rate will be shown in kbps.

You may specify a fixed transfer rate or Minimum

Guaranteed Rate with priority for non-used bandwidth.

Non-Assigned Bandwidth Ratio

: This field shows the available bandwidth ratio, for LAN to

WAN and WAN to LAN, that has not yet assigned.

: Press this button to add a new QOS policy.

: Before using these buttons to edit or delete a policy, please select one policy

you want to edit/delete from the radio option

.

: After you have configured the policies, you can press this button to apply the

Rate
