it’s enough to go to Internet after making basic setting without doing any changes. However, to
connect Internet still needs some ISPs to provide advanced detail information. Therefore, please
refer to the following explaination of the detail setting.
3.3.1 Configure
2WAN 3LAN VPN QoS Security Router
10
Host Name and Domain Name
Device name and domain name can be input in the two boxes. Though this configuration
is not necessary in most environments, some ISPs in some countries may require it.
LAN Setting
This is configuration information for the device current LAN IP address. The default
configuration is 192.168.1.1 and the default Subnet Mask is 255.255.255.0. Now it can
support to the IP Class C network and also it can be changed according to the actual network
structure.
Dual-WAN / DMZ Setting
It provides a configurable WAN 2 or DMZ port. First, choose this port as the second WAN
port or define it as DMZ mode, and then keep doing the following setting.
DMZ Setting
For some network environments, an independent DMZ port may be required to set up
externally connected servers such as WEB and Mail servers. Therefore, the device supports
a set of independent DMZ ports for users to set up connections for servers with real IPs. The
2WAN 3LAN VPN QoS Security Router
11
DMZ ports act as bridges between the Internet and LANs.
Subnet：
The DMZ and WAN located in different Subnets
For example: If the ISP issued 16 real IP addresses: 220.243.230.1-16 with Mask
255.255.255.240, users have to separate the 16 IP addresses into two groups: 220.243.230.1-8
with Mask 255.255.255.248, and 220.243.230.9-16 with Mask 255.255.255.248 and then set the
device and the gateway in the same group with the other group in the DMZ.
Range：
DMZ and WAN within same Subnet
IP Range for DMZ port: Put IP range in DMZ port.
After the changes are completed, click “Apply” to save the configuration, or click “Cancel"
to leave without making any changes.
2WAN 3LAN VPN QoS Security Router
12
WAN Connection Type
Obtain an IP automatically
This mode is often used in the connection mode to obtain an automatic DHCP IP. This is the
device system default connection mode. It is a connection mode in which DHCP clients obtain an
IP address automatically, which is often applied in Cable Modem or DHCP Client connection mode,
etc. If having a different connection mode, please refer to the following introduction for selection
of appropriate configurations. Users can also set up their own DNS IP address (Use the Following
DNS Server Address). Check the options and input the user-defined DNS IP addresses.
Static IP
If ISP issue a static IP (such as one IP or eight IPs, etc.), please select this connection mode
and follow the steps below to input the IP numbers issued by ISP into the relevant boxes.
Attention: Even if ISP offers a static IP address, it might be an automatic mode to
obtain a DHCP IP or to obtain a PPPoE dial-up IP. Although the IP address obtained will be
the same each time, users still must select the correct connecting mode!
2WAN 3LAN VPN QoS Security Router
13
Specify WAN
IP address:
Input the available static IP address issued by ISP.
Subnet Mask: Input the subnet
mask of the static IP address issued by ISP, such
as:
Issued eight static IP addresses: 255.255.255.248
Issued 16 static IP addresses: 255.255.255.240
Default
Gateway
Address:
Input the default gateway issued by ISP. For ADSL users, it is
usually an ATU-
R IP address. As for optical fiber users, please input
the optical fiber switching IP.
Domain Name
Server (DNS)：：：：
Input the DNS IP address issued by ISP. At least one IP group
should be input. The maximum acceptable is two IP groups.
Point-to-Point Protocol over Ethernet
This option is for an ADSL virtual dial-up connection (suitable for ADSL PPPoE). Input the user
connection name and password issued by ISP. Then use the PPP Over-Ethernet software built into
the device to connect with the Internet. If the PC has been installed with the PPPoE dialing
software provided by ISP, remove it. This software will no longer be used for network connection.
2WAN 3LAN VPN QoS Security Router
14
User Name: Input the user name issued by ISP.
Password Input the password issued by ISP.
Connect on
Demand:
This function enables the auto-
dialing function to be used in a
PPPoE dial connection. When the client port attempts to
connect with the Internet, the device will automatically make a
dial connection. If the line has been idle for a period of time,
the system will break the connection automatically. (The
default time for automatic break-
off resulting from no packet
transmissions is five minutes).
Keep Alive: This function enables the PPPoE dial connection to keep
connected, and to automatically redial if the line is
interrupted. It also enables a user to set up a time for
redialing. The default is 30 seconds.
After the changes are completed, click “Apply” to save the configuration, or click
“Cancel" to leave without making any change.
3.3.2 Dual WAN
If you have chosen the second WAN, then you can employment this setting.
Network Service Detection
2WAN 3LAN VPN QoS Security Router
15
Network Service Detection System:
This is a detection system for network external services. If this option is selected,
information such “Retry Count” or “Retry Timeout” will be displayed. If two WANs
are used for external connection, be sure to activate the NSD system, so as to avoid
any unwanted break caused by the device misjudgment of the overload traffic for the
WAN.
Retry Count: This selects the retry times for network service detection. The
default is five times. If there is no feedback from the Internet in
the configured “Retry Times", it will be judged as “External
Connection Interrupted”.
Retry Timeout: Delay time for external connection detection latency. The default
is 30 seconds. After the retry timeout, external service detection
will restart.
When Fail: (1) Generate the Error Condition in the System Log: If an ISP
connection failure is detected, an error message will be
recorded in the System Log. This line will not be removed;
therefore, the some of the users on this line will not have
normal connections.
This option is suitable under the condition that one of the WAN
2WAN 3LAN VPN QoS Security Router
16
connections has failed; the traffic going through this WAN to
the destination IP cannot shift to another WAN to reach the
destination. For example, if users want the traffic to 10.0.0.1
~ 10.254.254.254 to go only through WAN1, while WAN2 is
not to support these destinations, users should select this
option. When the WAN1 connection is interrupted, packets for
10.0.0.1~10.254.254.254 cannot be transmitted through
WAN 2, and there is no need to remove the connection when
WAN 1 is interrupted.
(2) Remove the Connection: If an ISP connection failure is
detected, no error message will be recorded in the System
Log. The packet transmitted through this WAN will be shifted
to the other WAN automatically, and be shifted back again
when the connection for the original WAN is repaired and
reconnected.
This option is suitable when one of the WAN connections fails
and the traffic going through this WAN to the destination IP
should go through the other WAN to reach the destination. In
this way, when any of the WAN connections is broken, other
WANs can serve as a backup; traffic can be shifted to a WAN
that is still connected.
Detecting Feedback Servers:
Default
Gateway:
The local default communication gateway location, such as the
IP address of an ADSL router, will be input automatically by the
device. Therefore, users just need to check the option if this
function is needed. Attention! Some gateways of an ADSL
network will not affect packet detection. If users have an optical
fiber box, or the IP issued by ISP is a public IP and the gateway
is located at the port of the net café rather than at the IP
provider’s port, do not activate this option.
ISP Server: This is the detected location for the ISP port, such as the DNS IP
address of ISP. When configuring an IP address for this function,
make sure this IP is capable of receiving feedback stably and
speedily. (Please input the DNS IP of the ISP port)
2WAN 3LAN VPN QoS Security Router
17
Remote Server: This is the detected location for the remote Network Segment.
This Remote Host IP should better be capable of receiving
feedback stably and speedily. (Please input the DNS IP of the ISP
port).
Use DNS server
for Domain
Name Service:
This is the detect location for DNS. (Only a web address such as
www.hinet.net is acceptable here. Do not input an IP address.)
In addition, do not input the same web address in this box for
two different WANs.
Apply: After the changes are completed, click “Apply” to save the
network configuration modification.
Cancel: Click “Cancel" to leave without making any change, but only it
works before you click apply button.
Bandwidth
Automatic load balance ratio will be made according to the upstream bandwidth users input for
the two WAN ports. For instance, if the upstream bandwidth for both WANs is 512Kbit/sec, the
automatic balance ratio will be 1:1. If one WAN upstream bandwidth is 1024Kbit/sec while the
other is 512Kbit/sec, the automatic balance ratio will be 2:1. Therefore, to ensure the load can
be really balanced, please input the actual upstream and downstream bandwidth. In addition,
the data users input will also affect the QoS configuration. Please refer to QoS Configuration.
Protocol Binding
Users can define specific IP addresses or specific application service ports to go through a
user-assigned WAN for external connections. For any other unassigned IP addresses and
services, WAN load balancing will still be carried out.
2WAN 3LAN VPN QoS Security Router
18
Service: This is to select the Binding Service Port to be activated. The
default (such as ALL-TCP&UDP 0~65535, WWW 80~80, FTP 21 to
21, etc.) can be selected from the pull-down option list. The default
Service is All 0~65535.
Option List for Service Management: Click the button to enter the
Service Port configuration page to add or remove default Service
Ports on the option list.
Source IP: Users can assign packets of specific Intranet virtual IP to go
through a specific WAN port for external connection. In the boxes
here, input the Intranet virtual IP address range; for example, if
192.168.1.100~150 is input, the binding range will be 100~150. If
only specific Service Ports need to be designated, while specific IP
designation is not necessary, input “0” in the IP boxes.
Destination
IP:
In the boxes, input an external static IP address. For example, if
connections to destination IP address 210.11.1.1 are to be
2WAN 3LAN VPN QoS Security Router
19
restricted to WAN1, the external static IP address 210.1.1.1 ~
210.1.1.1 should be input. If a range of destinations is to be
assigned, input the range such as 210.11.1.1 ~ 210.11.255.254.

3.3.3 QoS
QoS is an abbreviation for Quality of Service. The main function is to restrict bandwidth
usage for some services and IPs to save bandwidth or provide priority to specific
applications or services, and also to enable other users to share bandwidth, as well as to
ensure stable and reliable network transmission. To maximize the bandwidth efficiency,
network administrators should take account of the practical requirements of a company, a
community, a building, or a café etc, and modify bandwidth management according to the
network environment, application processes or services.
QoS Setting
In the boxes for WAN1 and WAN2 bandwidth, input the upstream and downstream
bandwidth which users applied for from bandwidth supplier. The bandwidth QoS will make
calculations according to the data users input. In other words, it will guarantee a minimum
rate of upstream and downstream for each IP and Service Port based on the total actual
bandwidth of WAN1 and WAN2. For example, if the upstream bandwidths of both WAN1 and
WAN2 are 512Kbit/Sec, the total upstream bandwidth will be: WAN1 + WAN2 =
1024Kbit/Sec. Therefore, if there are 50 IPs in the Intranet, the minimum guaranteed
upstream bandwidth for each IP would be 1024Kbit/50=20Kbit/Sec. Thus, 20Kbit/Sec can
be input for “Mini. Rate” Downstream bandwidth can be calculated in the same way.
Session Control
Session management controls the acceptable maximum simultaneous connections of
Intranet PCs. This function is very useful for managing connection quantity when P2P
software such as BT, Thunder, or emule is used in the Intranet causing large numbers of
connections. Setting up proper limitations on connections can effectively control the
connections created by P2P software. It will also have a limiting effect on bandwidth usage.

In addition, if any Intranet PC is attacked by a virus like Worm.Blaster and sends a huge
number of connection requests, session control will restrict that as well.

Disable: To disable Session Control function.
Single IP cannot
exceed ___ Session
This option enables the restriction of
maximum external
connections to each Intranet PC. When the number of
external connections reaches the limit, to allow new
connections to be built, some of the existing connections
must be closed. For example, when BT or P2P is being
used to download information and the connections
exceed the limit, the user will be unable to connect with
other services until either BT or P2P is closed.
Network Service
Detection:
(When single IP
exceed limit)
If this function is selected, when the user’s port
connection reach the limit, this user will not be able to
make a new connection for five minutes. Even if the
previous connection has been closed, new connections
cannot be made until the setting time ends.
If this function is selected, when the user’s port
connections reach the limit, all the lines that this user is
connected with will be removed, and the user will not be
able to connect with the Internet for five minutes. New
connections cannot be made until the delay time ends.
Scheduling If “Always
” is selected, the rule will be executed around
the clock. If “From…” is selected, the rule will be
executed according to the configured time range. For
example, if the time control is from Monday to Friday,
8:00am to 6:00pm, users can refer to the following
figure to set up the rule.
Days Management: If “Everyday” is selected, the rule will be activated for
the control time range every day. Users can choose to
activate the rule during certain days of the week.

Service Management: To add or remove a Service Port.
Source IP/Group: To add IP addresses/Groups that are free from
restriction.
Enable: To activate the added rule.
Add To List: To add the rule into the list.
Apply: Click the “Apply” button to save the modification.
Cancel: Click the “Cancel” button to cancel the modification.
This only works before “Apply” is clicked.
QoS Configuration
There are two options for bandwidth management: one is Rate Control, the other is
Priority Control. The two kinds of management cannot be used at the same time. Network
administrators must choose one or the other based on the Intranet needs.
Rate Control：
The network administrator can set up bandwidth or usage limitations for each IP or IP
range according to the actual bandwidth. The network administrator can also set bandwidth
control for certain Service Ports. A guarantee bandwidth control for external connections
can also be configured if there is an internal server.

Interface: To select on which WAN the QoS rule should be executed. It can be
a single selection or multiple selections.
Service: To select what bandwidth control is to be configured in the QoS
rule. If the bandwidth for all services of each IP is to be controlled,
select “All (TCP&UDP) 1~65535”. If only FTP uploads or downloads
need to be controlled, select “FTP Port 21~21”. Refer to the Default
Service Port Number List.
IP: This is to select which user is to be controlled. If only a single IP is
to be restricted, input this IP address, such as “192.168.1.100 to
100”. The rule will control only the IP 192.168.1.100. If an IP range
is to be controlled, input the range, such as “192.168.1.100 ~
150”. The rule will control IPs from 192.168.1.100 to 150. If all
