Parental Control Provider

Parental Control Provider provides Web content filtering offering safer and more reliable web surfing

for users. Please get an account and configure at the selected Provider “www.opendns.com” in

advance. To use parental control (DNS), user needs to configure to use parental control (DNS

provided by parental control provider) to access internet at WAN configuration or DNS page(See

DNS

).

Host Name, Username and Password:

Enter your registered domain name and your username

and password at the provider website

QoS - Quality of Service

Quality of Service

QoS helps you to control the data upload traffic of each application from LAN (Ethernet) to WAN

(Internet). This feature allows you to control the quality and speed of throughput for each application

when the system is running with full upstream load.

Note:

ADSL line speed is based on the ADSL sync rate. But there is no QoS on 3G/LTE as the

3G/LTE line speed is various and can not be known exactly.

EWAN Line Speed

Upstream / Downstream:

Specify the upstream and downstream rate of the EWAN interface.

Click

Apply

to save the EWAN rate settings.

Click

Add

to enter QoS rules.

IP Version:

Select either IPv4 or IPv6 base on need.

Application:

Assign a name that identifies the new QoS application rule. Select from the list box for

quick setup.

Direction:

Shows the direction mode of the QoS application.



LAN to WAN:

You want to control the traffic from local network to the outside (Upstream).

You can assign the priority for the application or you can limit the rate of the application.

Eg:

you have a FTP server inside the local network, and you want to have a limited control by

the QoS policy and so you need to add a policy with LAN to WAN direction setting.



WAN to LAN:

Control traffic from WAN to LAN (Downstream).

Protocol:

Select the supported protocol from the drop down list.

DSCP Marking:

Differentiated Services Code Point (DSCP), it is the first 6 bits in the ToS byte.

DSCP Marking allows users to classify the traffic of the application to be executed according to the

DSCP value.

DSCP offers three levels of service, Class Selector (CS), Assured Forwarding (AF) and Expedited

Forwarding (EF). AF1, AF2, AF3 and AF4 are four levels of assured forwarding services. Each AF

has three different packet loss priorities from high, medium, to low. Also, CS1-CS7 indicates the IP

precedence.

Rate Type:

You can choose

Limited

,

Prioritization

or

Set DSCP Marking

.



Limited (Maximum):

Specify a limited data rate for this policy. It also is the maximum rate

for this policy. When you choose

Limited

, type the

Ratio

proportion. As above FTP server

example, you may want to “throttle” the outgoing FTP speed to 20% of 256K and limit to it,

you may use this type.



Prioritization:

Specify the rate type control for the rule to be used. If you choose

Prioritization

for the rule, you parameter

Priority

would be available, you can set the priority

for this rule.



Set DSCP Marking:

When select

Set DSCP Marking

, the packets matching the rule will be

forwarded according to the pre-set DSCP marking.

Ratio:

The rate percent of each application/policy compared to total traffic on the interface with

limited rate type.

For example, we want to only allow 20% of the total data for the LAN-to-WAN

direction to be used for FTP server. Then we can specify here with data ratio = 20. If you have ADSL

LINE with 256K/bps.rate, the estimated data rate, in kbps, for this rule is 20%*256*0.9 = 46kbps.

(For 0.9 is an estimated factor for the effective data transfer rate for an ADSL LINE from LAN to

WAN. For WAN-to-LAN, it is 0.85 to 0.8)

Priority:

Set

the priority given to each policy/application.

Specify the priority for the use of bandwidth.

You can specify which application can have higher priority to acquire the bandwidth.

Its default

setting is set to Normal. You may adjust this setting to fit your policy / application.

Internal IP Address:

The IP address values for Local LAN devices you want to give control.

Internal Port:

The Port number on the LAN side, it is used to identify an application.

External IP Address:

The IP address on remote / WAN side.

External Port:

The Port number on the remote / WAN side.

Time Schedule:

Select or set exactly when the rule works. When set to “Always On”, the rule will

work all time; and also you can set the precise time when the rule works, like 01:00- 19:00 from

Monday to Friday. Or you can select the already set timeslot in “

Time Schedule

” during which the

rule works. And when set to “Disable”, the rule is disabled or inactive and there will be an icon”

” indicating the rule is inactive. See

Time Schedule

.

Examples:

Common usage

1. Give outgoing VoIP traffic more priority.

The default queue priority is normal, so if you have VoIP users in your local network, you can set a

higher priority to the outgoing VoIP traffic.

2. Give regular web http access a limited rate
