Multi-WAN Router
I. Introduction
Multi-WAN Router (referred as Router hereby) is a business level firewall router that efficiently
integrates new generation multiple WAN-port firewall devices. It meets the needs of both medium and
large-scale enterprises, internet cafes, and communities, etc. The Router focuses on multiple ISP
environment and user bandwidth management requirement to integrate the gigabit backbone networking, it
can support hardware port mirror, smart QoS, Multi-WAN load balance, gateway redundancy, and Intelligent
Firewall.
Router uses a high-level processor and maximum 2Gbps-two way forwarding rate that can support
several hundred thousand session connections, built-in high- capacity RAM allows the stability and reliability
for long-time operation.
It provides 3~4 Gigabit WAN ports and high-efficiency load balance mode for out-bound load balance.
WAN side outbound connection performance can fulfill most of the standards for broadband market. In
addition, configurable DMZ port can connect to the public server by public IP address. It has a built-in 1~2
Gigabit backbone LAN port to appropriate for 10/100/1000Mbps Ethernet switch and each port can connect
with other switches for more network devices that can build up a Gigabit backbone conveniently to accelerate
the network availability and scalable bandwidth enterprise. In addition, there is an USB interface that can
support other device connections, enlarge storage capacity, and other future functions.
Individual QoS bandwidth management with powerful and easy-to-setup functions allows manager to
arrange the limited network resource rational and efficiently. It is not needed to extend the bandwidth to
unlimited settings which would increase spending cost; it can also avoid the complaint of few people to force
whole bandwidth. Simple user configuration can be the best efficiency application; it allows the optimization of
bandwidth utilization based on the whole utility rate without setting rules step-by-step and only to limit the
users who occupy the bandwidth for resource savings. Moreover, intelligence bandwidth management is
provided, through the simple deployment to complete LAN side bandwidth management for efficiency utility
rate, simple management and improvement performance.
The Router exclusively provides hardware optimization, which can run broad bandwidth management,
traffic priorities and distributions directly through hardware. Not only can it ensure intranet important services
won’t have disconnection, but also decrease the depletion of CPU and the whole system resources. Thus, the
Router can endure enormous sessions and PCs, and provide stable network environment.
Load balancing function supports Auto Load Balance mode, Specify WAN Binding mode and Strategy
Routing mode to allow deployment of flexible network connection required to control traffic flow to guarantee
3
Multi-WAN Router
that whole connections are unobstructed. Strategy Routing mode is simply to configure the network without
the input of IP address. It can automatically detect outbound packets and filter telecom connection to ensure
quick response and packet pass through without obstruction, and it can aggregate the same ISP bandwidth
for load balancing control and increase flexibility of network resource.
Built-in Firewall system can fulfill market requirement in defense of internet attacks for most enterprise.
Initiative packet inspection via the network layer dynamic detection denies or blocks non-standard protocol
connections. It can easily employ complete protection functions to ensure network security, as required for
any kind of hack attacks, worm & Virus and ARP attacks by one-way control. Firewall system has not only
NAT function but also DoS attack. Complete Functions of Access Rules can allow managers to select the
network service levels to deny or allow accesses, and it can also limit or deny LAN users to use the network
and to avoid the network resource being occupied or threatened due to improper uses.
NAT function can provide the translation between private IP and public IP, which can allow multi-user to
connect the internet with one public IP at the same time. LAN IP supports four Class C connections, and
DHCP server is also supported, as well as an easy configuration of IP-MAC binding function allowing network
structure to be flexible and easy to deployed and managed.
In addition, the Router also supports virtual routing function. One-WAN branch can be upgraded to
dual-WAN transmit ion easily, Enterprise with one-WAN can connect to dual-WAN center by easy
configuration and traffic will pass through other WAN lines from the center network. This can also accelerate
the connections among different areas to solve the connection bottleneck problem.

6.2.1 Load Balance Mode
Auto Load Balance Mode
When Auto Load Balance mode is selected, the device will use sessions or IP and the WAN bandwidth
automatically allocate connections to achieve load balancing for external connections. The network bandwidth
is set by what users input for it. For example, if the upload bandwidth of both WANs is 512Kbit/sec, the
39
Multi-WAN Router
automatic load ratio will be 1:1; if one of the upload bandwidths is 1024Kbit/sec while the other is 512Kbit/sec,
the automatic load ratio will be 2:1. Therefore, to ensure that the device can balance the actual network load,
please input real upload and download bandwidths.
Session Balance: If “By Session” is selected, the WAN bandwidth will automatically
allocate connections based on session number to achieve network load balance.
IP Session Balance: If “By IP” is selected, the WAN bandwidth will automatically allocate
connections based on IP amount to achieve network load balance.
Note!
For either session balancing or IP connection balancing, collocation with Protocol Binding will
provide a more flexible application for bandwidth. Users can assign a specific Intranet IP to go
through a specific service provider for connection, or assign an IP for a specific destination to go
through the WAN users assign to connect with the Internet.
For example, if users want to assign IP 192.168.1.100 to go through WAN 1 when connecting
with the Internet, or assign all Intranet IP to go through WAN 2 when connecting with servers with
port 80, or assign all Intranet IP to go through WAN 1 when connecting with IP 211.1.1.1, users
can do that by configuring “Protocol Binding”.
Attention! When the Auto Load Balance mode is collocated with Protocol Binding, only IP
addresses or servers that are configured in the connection rule will follow the rule for external
connections; those which are not configured in the rule will still follow the device Auto Load
Balance system.
Please refer to the explanations in 6.2.3 Configuring Protocol Binding for setting up
Protocol Binding and for examples of collocating router modes with Protocol Binding.
Exclusive Mode
This mode enables users to assign specific intranet IP addresses, destination application service ports or
destination IP addresses to go through an assigned WAN for external connection. After being assigned, the
specific WAN will only support those assigned Intranet IP addresses, specific destination application service
ports, or specific destination IP addresses. Intranet IP, specific destination application service ports and
specific destination IP that is not configured under the rules will go through other WANs for external
connection. For unassigned WANs, users can select Load Balance mode and select session or IP for load
balancing.
●
Session Balance: If “By Session” is selected, the WAN bandwidth will automatically
40
Multi-WAN Router
allocate connections based on session number to achieve network load balance.
●
IP Balance: If “By IP” is selected, the WAN bandwidth will automatically allocate
connections based on the number of IP addresses to achieve network load balance.
Note!
Only when a device assignment is collocated with Protocol Binding can the balancing function
be brought into full play. For example, an assignment requiring all Intranet IP addresses to go
through WAN 1 when connecting with service port 80, or go through WAN 1 when connecting with
IP 211.1.1.1, must be set up in the Protocol Binding Configuration.
Attention: When assigning mode is selected, as in the above example, the IP(s) or service
provider(s) configured in the connection rule will follow the rule for external connections, but those
which are not configured in the rule will still follow the device Load Balance system to go through
other WAN ports to connect with the Internet.
Please refer to the explanations in 6.2.3 Configuring Protocol Binding for setting up
Protocol Binding and for examples of collocating router mode with Protocol Binding.
Strategy Routing Mode
If strategy Routing is selected, the device will automatically allocate external connections based on
routing policy (Division of traffic between Telecom and Netcom is to be used in China) embedded in the device.
All you have to do is to select the WAN (or WAN group) which is connected with Netcom; the device will then
automatically dispatch the traffic for Netcom through that WAN to connect with the Internet and dispatch traffic
for Telecom to go through the WAN connected with Telecom to the Internet accordingly. In this way, the traffic
for Netcom and Telecom can be divided.
Set WAN Grouping:
If more than one WAN is connected with Netcom, to apply a similar division of traffic policy to these
WANs, a combination for the WANs must be made. Click “Set WAN Grouping”; an interactive window as
shown in the figure below will be displayed.
41
Multi-WAN Router
Name:
To define a name for the WAN grouping in the box, such as
“Education” etc. The name is for recognizing different WAN groups.
Interface:
Check the boxes for the WANs to be added into this combination.
Add To List:
To add a WAN group to the grouping list.
Delete selected
To remove selected WANs from the WAN grouping.
Item:
Apply:
Click “Apply” to save the modification.
Close:
Click “Cancel” to cancel the modification. This only works before
“Apply” is clicked.
After the configuration is completed, in the China Netcom Policy window users can select WANs in
combination to connect with Netcom.
Import Strategy:
A division of traffic policy can be defined by users too. In the “Import Strategy” window, select the WAN or
WAN group (ex. WAN 1) to be assigned and click the “Import IP Range” button; the dialogue box for document
importation will be displayed accordingly. A policy document is an editable text document. It may contain a
destination IP users designated. After the path for document importation has been selected, click “Import”,
and then at the bottom of the configuration window click “Apply”. The device will then dispatch the traffic to the
assigned destination IP through the WAN (ex. WAN 1) or WAN grouping users designated to the Internet.
42
Multi-WAN Router
To build a policy document users can use a text-based editor, such as Notepad, which is included with
Windows system. Follow the text format in the figure below to key in the destination IP addresses users want
to assign. For example, if the destination IP address range users want to designate is 140.115.1.1 ~
140.115.1.255, key in 140.115.1.1 ~ 140.115.1.255 in Notepad. The next destination IP address range should
be keyed in the next line. Attention! Even if only one destination IP address is to be assigned, it should follow
the same format. For example, if the destination IP address is 210.66.161.54, it should be keyed in as
210.66.161.54~210.66.161.54. After the document has been saved (the extension file name is .txt), users can
import the IP range of self-defined strategy.
43
Multi-WAN Router
Note!
China Netcom strategy and self-defined strategy can coexist. However, if a destination IP
is assigned by both China Netcom strategy and self-defined strategy, China Netcom strategy
will take priority. In other words, traffic to that destination IP will be transmitted through the
WAN (or WAN group) under China Netcom strategy.
Session Balance Advanced Function
In general, session balance is to equally and randomly distribute the session connections of each
intranet IP. For some special connections, for example, web banking encrypted connection (Https or
TCP443), is required to connect from the same WAN IP. If one intranet IP visits web banking website and the
connection is distributed into different WAN IP addresses, there will be disconnection or failure.
Session
balance advanced function targets at solving this issue.
Session balance advanced function can set the same intranet IP keeps having sessions from the same
WAN IP for some specific service protocols. Other service protocols can still adopt the original balance
mechanism to distribute the sessions equally and randomly. With the original session balance efficiency,
advanced function can ensure the connection running without error for some special service protocols.
Click “Advanced Function” to enter the setting window:
44
Multi-WAN Router
Destination Auto Binding
Indicates that the session will be connected with the same WAN IP
when the destination IP is in the same Class B range.
For example, there are WAN1-1 200.10.10.1 and WAN2- 200.10.10.2, and two intranet IP addresses. When
192.168.1.100 visits Internet 61.222.81.100 for the first time, the connection is through WAN1- 200.10.10.1.
If the next destination is to 61.222.81.101 (in the same Class B range), the connection will also be through
WAN1- 200.10.10.1. If the destination is to other IP not in the same Class B range as 61.222.81.100, the
session will be distributed in the orginal session balance mechanism.
When the other intranet IP 192.168.1.101 visits 61.222.81.101 for the first time, the connection is through
WAN2- 200.10.10.2. If the next destination is to 61.222.81.100 (in the same Class B range), the connection
will also be through WAN2 200.10.10.2. If the destination is to other IP not in the same Class B range as
61.222.81.100), the session will be distributed in the orginal session balance mechanism.
Note!
Not all intranet IP will visit the same Class B range with the same WAN IP.

It depends on which WAN
If the destination IP is in the same Class B range, the connection will go

User Define Dis. Or Port Auto
Indicates that the intranet IP will connect through the same WAN IP
Binding
when the service ports are self- defined.
You can self- define the service ports and destination IP. (If the
destination IP is set as 0.0.0.0 to 0, this represents that the destination
is to any IP range.)
Note!
You can only choose either Destimation Auto Binding or User Define
Dis. Or Port Auto Binding.
Take default rules for example:
When any intranet IP connects with TCP443 port or any destination (0.0.0.0 to 0 represents any destination),
46
Multi-WAN Router
it will go through the same WAN IP. As for which WAN will be selected, this follows the first- chosen WAN IP
distributed by the original session balance mechanism. For example, there are two intranet IP192.168.100.1 and 192.168.100.2. When these intranet IPs first connects with TCP443 port, 192.168.100.1
will go through WAN1, and 192.168,100.2 will go through WAN2.
Afterwards, 192.168.100.1 will go through
WAN1 when there are TCP443 port connections. 192.168.100.2 will go through WAN2 when there are
TCP443 port connections.
This rule is by default.
You can delete or add rules to meet your connection requirement.
6.2.2 Network Detection Service
This is a detection system for network external services. If this option is selected, information such
“Retry” 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.
Interface:
Select the WAN Port that enables Network Service Detection.
Retry:
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 Disconnected”.
47
Multi-WAN Router
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
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 disconnected, 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 disconnected.
(2) Keep System Log and 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.
48
Multi-WAN Router
ISP Host:
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)
Remote Host:
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).
DNS Lookup Host:
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.
Note!
!
In the load balance mode for Assigned Routing, the first WAN port (WAN1) will be saved for the
traffic of the IP addresses or the application service ports that are not assigned to other WANs (WAN2,
WAN3, and WAN4). Therefore, in this mode, we recommend assigning one of the connections to the
first WAN. When other WANs (WAN2, WAN3, or WAN4) are broken and connection error remove
(Remove the Connection) has been selected for the connection detection system, traffic will be shifted
to the first WAN (WAN1). In addition, if the first WAN (WAN1) is broken, the traffic will be shifted to other
WANs in turn. For example, the traffic will be shifted to WAN2 first; if WAN2 is broken too, the traffic will
be shifted to WAN3, and so on.
6.2.3 Protocol Binding
WAN Setting:
49
Multi-WAN Router
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.
Note!
!
In the load balance mode of Assigned Routing, the first WAN (WAN1) cannot be assigned. It is to
be saved for the IP addresses and the application Service Ports that are not assigned to other WANs
(WAN2, WAN3, and WAN4) for external connections. In other words, the first WAN (WAN1) cannot be
configured with the Protocol Binding rule. This is to avoid a condition where all WANs are assigned to
specific Intranet IP or Service Ports and destination IP, no more WAN ports will be available for other IP
addresses and Service Ports.
50

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,
51
Multi-WAN Router
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 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. This means the Class B Network
Segment of 210.11.x.x will be restricted to a specific WAN. If only
specific Service Ports need to be designated, while a specific IP
destination assignment is not required, input “0” into the IP boxes.

Auto Load Balancing mode when enabled:
The collocation of the Auto Load Balance Mode and the Auto Load Mode will enable more flexible
use of bandwidth. Users can assign specific Intranet IP addresses to specific destination application
service ports or assign specific destination IP addresses to a WAN users choose for external
connections.
Example 1:How do I set up Auto Load Balance Mode to assign the Intranet IP 192.168.1.100 to WAN2 for
the Internet?
As in the figure below, select “All Traffic” from the pull-down option list “Service”, and then in the
boxes of “Source IP” input the source IP address “192.168.1.100” to “100”. Retain the original numbers
“0.0.0.0” in the boxes of “Destination IP” (which means to include all Internet IP addresses). Select
WAN2 from the pull-down option list “Interface”, and then click “Enable”. Finally, click “Add New” and
the rule will be added to the mode.
54
Multi-WAN Router
Example 2:How do I set up Auto Load Balance Mode to keep Intranet IP 192.168.1.150 ~ 200 from going
through WAN2 when the destination port is Port 80?
As in the figure below, select “HTTP [TCP/80~80]” from the pull-down option list “Service”, and
then in the boxes for “Source IP” input “192.168.1.150” to “200”. Retain the original numbers “0.0.0.0”
in the boxes of “Destination IP” (which means to include all Internet IP addresses). Select WAN2 from
the pull-down option list “Interface”, and then click “Enable”. Finally, click “Add New” and the rule will be
added to the mode.
55
Multi-WAN Router
Example 3:How do I set up Auto Load Balance Mode to keep all Intranet IP addresses from going
through WAN2 when the destination port is Port 80 and keep all other services from going through
WAN1?
As in the figure below, there are two rules to be configured. The first rule: select “HTTP
[TCP/80~80]” from the pull-down option list “Service”, and then in the boxes of Source IP input
“192.168.1.0” to “0” (which means to include all Intranet IP addresses). Retain the original numbers
“0.0.0.0” in the boxes of “Destination IP” (Which means to include all Internet IP addresses). Select
WAN2 from the pull-down option list “Interface”, and then click “Enable”. Finally, click “Add New” and
the rule will be added to the mode. The device will transmit packets to Port 80 through WAN2. However,
with only the above rule, packets that do not go to Port 80 may be transmitted through WAN2; therefore,
a second rule is necessary. The second rule: Select “All Ports [TCP&UDP/1~65535]” from the
pull-down option list “Service”, and then input “192.168.1.2 ~ 254” in the boxes of “Source IP”. Retain
the original numbers “0.0.0.0” in the boxes of “Destination IP” (which means to include all Internet IP
addresses). Select WAN1 from the pull-down option list “Interface”, and then click “Enable”. Finally,
56
Multi-WAN Router
click “Add New” and the rule will be added to the mode. The device will transmit packets that are not
going to Port 80 to the Internet through WAN1.
Configuring “Assigned Routing Mode” for load Balance:
IP Group: This function allows users to assign packets from specific Intranet IP addresses or to
specific destination Service Ports and to specific destination IP addresses through an assigned WAN to
the Internet. After being assigned, the specific WAN will only support those assigned Intranet IP
addresses, destination Service Ports, or destination IP addresses. Those which are not configured will
go through other WANs for external connection. Only when this mode is collocated with “Assigned
Routing” can it bring the function into full play.
Example 1:How do I set up the Assigned Routing Mode to keep all Intranet IP addresses from going
through WAN2 when the destination is Port 80, and keep all other services from going through WAN1?
As in the figure below, select “HTTP[TCP/80~80]” from the pull-down option list “Service”, and
57
Multi-WAN Router
then in the boxes of “Source IP” input “192.168.1.0 ~ 0” (which means to include all Intranet IP
addresses). Retain the original numbers “0.0.0.0” in the boxes of “Destination IP” (Which means to
include all Internet IP addresses). Select WAN2 from the pull-down option list “Interface”, and then click
“Enable”. Finally, click “Add New” and the rule will be added to the mode. After the rule is set up, only
packets that go to Port 80 will be transmitted through WAN2, while other traffics will be transmitted
through WAN1.
Example 2:How do I configure Protocol Binding to keep traffic from all Intranet IP addresses from going
through WAN2 when the destinations are IP 211.1.1.1 ~ 211.254.254.254 as well as the whole Class A
group of 60.1.1.1 ~ 60.254.254.254, while traffic to other destinations goes through WAN1?
As in the following figure, there are two rules to be configured. The first rule: Select “All Port
[TCP&UDP/1~65535]” from the pull-down option list “Service”, and then in the boxes of “Source IP”
input “192.168.1.0 ~ 0” (which means to include all Intranet IP addresses). In the boxes for “Destination
IP” input “211.1.1.1 ~ 211.254.254.254”. Select WAN2 from the pull-down option list “Interface”, and
58
Multi-WAN Router
then click “Enable”. Finally, click “Add New” and the rule will be added to the mode. The second rule:
Select “All Port [TCP&UDP/1~65535]” from the pull-down option list “Service”, and then in the boxes of
“Source IP” input “192.168.1.0 ~ 0” (which means to include all Intranet IP addresses). In the boxes of
“Destination IP” input “211.1.1.1 ~ 60,254,254,254”. Select WAN2 from the pull-down option list
“Interface”, and then click “Enable”. Finally, click “Add New”, and the rule will be added to the mode.
After the rule has been set up, all traffic that is not going to the assigned destinations will only be
transmitted through WAN1.

To build a self-defined IP, users can use a text-based editor, such as Notepad, which is included with
Windows system. Follow the text format in the figure below to key in the destination IPs users want to assign.
For example, if the destination IP address range users want to designate is 140.115.1.1 ~ 140.115.1.255, key
in 140.115.1.1 ~ 140.115.1.255 in Notepad. The next destination IP address range should be keyed in the
next line. Attention! Even if only one destination IP address is to be assigned, it should follow the same format.
For
example,
if
the
destination
IP
address
is
210.66.161.54,
it
should
be
keyed
in
as

VII. Port Management
This chapter introduces how to configure ports and understand how to configure intranet IP addresses.
7.1 Setup
Through the device, users can easily manage the setup for WAN ports, LAN ports and the DMZ port by
choosing the number of ports, speed, priority, duplex and enable/disable the auto-negotiation feature for
connection setting of each port.
Mirror Port:Users can configure LAN 1 as mirror port by choosing “Enable Port 1 as Mirror Port”. All the
traffic from LAN to WAN will be copied to mirror port. Administrator can control or filter the traffic through
mirror port. Once this function is enabled, LAN 1 will be shown as Mirror Port in Physical Port Status, Home
page.
Disabled:
This feature allows users turn on/off the Ethernet port. If selected, the
Ethernet port will be shut down immediately and no connection can be
made. The default value is "on".
Priority:
This feature allows users to set the high/low priority of the packet delivery
for the Ethernet port. If it is set as High, the port has the first priority to
deliver the packet. The default value is “Normal”.
62
Multi-WAN Router
Speed:
This feature allows users to select the network hardware connection speed
for the Ethernet port. The options are 10Mbps and 100Mbps.
Duplex Status:
This feature allows users to select the network hardware connection speed
working mode for the Ethernet. The options are full duplex and half duplex.
Auto Neg.:
The Auto-Negotiation mode can enable each port to automatically adjust
and gather the connection speed and duplex mode. Therefore, if Enabled
Auto-Neg. selected, the ports setup will be done without any manual setting
by administrators.
VLAN:
This feature allows administrators to set the LAN port to be one or more
disconnected network sessions. All of them will be able to log on to the
Internet through the device.
Members in the same network session (within the same VLAN) can see and
communicate with each other. Members in different VLAN will not know the
existence of other members.
VLAN All:
Set VLAN All port to be the public area of VLAN so that it can be connected
to other VLAN networks. A server should be constructed for the intranet so
that all VLAN group can visit this server. Set one of the network ports as
VLAN All. Connect the server to VLAN All so that computers of different
VLAN groups can be connected to this server. Moreover, the port where the
administrator locates must be set as VLAN All so that it can be connected to
the entire network to facilitate network management.
7.2 Port Status
63
Multi-WAN Router
Summary:
There are Network Connection Type, Interface, Link Status (Up/Down), Port Activity (Port Enabled),
Priority Setting (High or Normal), Speed Status (10Mbps, 100Mbps or 1000Mbps), Duplex Status (half duplex
or full duplex), Auto Neg. (Enabled/Disabled), and VLAN.
Statistics:
The packet data of this specific port will be displayed. Data include receive/ transmit packet count,
receive/ transmit packet Byte count and error packet count. Users may press the refresh button to update all
real-time messages.
7.3 IP/ DHCP
64
Multi-WAN Router
With an embedded DHCP server, it supports automatic IP assignation for LAN computers. (This function
is similar to the DHCP service in NT servers.) It benefits users by freeing them from the inconvenience of
recording and configuring IP addresses for each PC respectively. When a computer is turned on, it will acquire
an IP address from the device automatically. This function is to make management easier.
Dynamic IP:
Enable DHCP Server
Check the option to activate the DHCP server automatic IP lease
function. If the function is activated, all PCs will be able to acquire IP
automatically. Otherwise, users should configure static virtual IP for each
PC individually.
65
Multi-WAN Router
This is to set up a lease time for the IP address which is acquired by a
Client lease Time:
PC. The default is 1440 minutes (a day). Users can change it according
to their needs. The time unit is minute.
This is an initial IP automatically leased by DHCP. It means DHCP will

shown in the following figure.
68
For example, LAN is 10.10.10.1, as
Multi-WAN Router
Therefore, DCHP DNS IP address must be 10.10.10.1 to make DNS local database in effect.
(3) After enabling DNS local database, if there is no host domain names in the list, the router will still use ISP
DNS server or internal DNS server for lookup.
Test if DNS local database is effective:
Assumed tw.yahoo.com IP address is 10.10.10.199, as the following figure.
(1) System Tool => Diagnostic => DNS Name Lookup
69

7.5 IP & MAC Binding
Administrators can apply IP & MAC Binding function to make sure that users can not add extra PCs for
Internet access or change private IP addresses.
There are two methods for setting up this function:
Block MAC address not on the list
This method only allows MAC addresses on the list to receive IP addresses from DHCP and have
Internet access. When this method is applied, please fill out Static IP with 0.0.0.0, as the figure below:
71
Multi-WAN Router
72
Multi-WAN Router
IP & MAC Binding
Static IP:
There are two ways to input static IP:
1.
If users want to set up a MAC address to acquire IP from
DHCP, but the IP need not be a specific assigned IP,
input 0.0.0.0 in the boxes. The boxes cannot be left
empty.
2.
If users want DHCP to assign a static IP for a PC every
single time, users should input the IP address users want
to assign to this computer in the boxes. The server or PC
which is to be bound will then acquire a static virtual IP
whenever it restarts.
MAC Address:
Input the static real MAC (the address on the network card) for
the server or PC which is to be bound.
73
Multi-WAN Router
For distinguishing clients, input the name or address of the
Name:
client that is to be bound. The maximum acceptable characters
are 12.
Enabled:
Activate this configuration.
Add to list:
Add the configuration or modification to the list.
Delete selected item:
Remove the selected binding from the list.
Add:
Add new binding.
Block MAC address on the list with wrong IP address: When this option is activated, MAC addresses
which are not included in the list will not be able to connect with the Internet.
Show New IP user:
This function can reduce administrator’s effort on checking MAC addresses one by one for the binding.
Furthermore, it is easy to make mistakes to fill out MAC addresses on the list manually. By checking this list,
administrator can see all MAC addresses which have traffic and are not bound yet. Also, if administrators find
that one specific bound MAC address is shown on the list, it means that the user changes the private IP
address.
Name:
Input the name or address of the client that is to be bound. The maximum
acceptable characters are 12.
Enabled:
Choose the item to be bound.
Apply:
Activate the configuration.

7.6 IP Grouping
IP Group function can combine several IP addresses or IP address ranges into several groups. When you
manage user internet access privileges by IP address, you can set up every management functions for users
who have same internet access privileges in the same IP group in order to decrease the effort of setting rules
for each IP address. For example, you can choose to set up QoS or Access Rule by IP grouping. Thus, you
will simplify setting rules.
IP Grouping consists of Local IP Group and Remote IP Group. Local IP Group refers to LAN IP groups,
and remote IP Group refers to WAN IP groups. Local IP Group list will automatically learn IP addresses having
packets that pass through firewall. Moreover, if user changes the IP address, the IP in the list will change
accordingly well. For IP information which is in group list, it won't update automatically along with IP list of the
left side. Administrators need to modify it manually.
User Edit IP
The IP list will show the list which learns the IP addresses automatically on the left
under side. You can also modify IP addresses manually.
Name
Input the name of IP address (or range) showed below.
IP Address
Input IP address (or range). For example, 192.168.1.200 ~ 250.
Add to IP List
After setting name and IP address, push this button to add the information into the
IP list below. If this IP (or range) is already in the list, you can not add it again.

Remote IP Group Management:
Basically, Remote IP Group setups are exactly the same as Local IP Group setups. However, remote IP
group does not have automatically learning functions. Instead, you need to define addresses, ranges and
groups manually. For example, 220.130.188.1 to 200 (range).
It is the same setting methods. You should set the IP address or the range of remote IP from the left side
76
Multi-WAN Router
first, and choose to add IP address information from the left side into the remote group.
77

VIII. QoS (Quality of Service)
QoS is an abbreviation for Quality of Service. The main function is to restrict bandwidth usage for some
services and IP addresses 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.
80
Multi-WAN Router
8.1 Bandwidth Management
8.1.1 The Maximum Bandwidth provided by ISP
81
Multi-WAN Router
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 IP addresses 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.
Attention!
The unit of calculation in this example is Kbit. Some software indicates the downstream/upstream
speed with the unit KB. 1KB = 8Kbit.
8.1.2 QoS
To satisfy the bandwidth requirements of certain users, the device enables users to set up QoS: Rate
Control and Priority Control. Users can select only one of the above QoS choices.
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.
82
Multi-WAN Router
Interface:
Select on which WAN the QoS rule should be executed. It can be a single
selection or multiple selections.
Service Port:
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.
83
Multi-WAN Router
IP Address:
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 IP addresses from
192.168.1.100 to 150. If all Intranet users that connect with the device are to
be controlled, input “0” in the boxes of IP address. This means all Intranet IP
addresses will be restricted. QoS can also control the range of Class B.
Direction:
Upstream: Means the upload bandwidth for Intranet IP.
Downstream: Means the download bandwidth for Intranet IP.
Server in LAN, Upstream: If a Server for external connection has been built in
the device, this option is to control the bandwidth for the traffic coming from
outside to this Server.
Server in LAN, Downstream: If there are web sites built in the Intranet, this
option is to control the upload bandwidth for the connections from outside to
this Server. For example, game servers have been built in many Internet
cafés. This rule can be used to control the bandwidth for connections from
outside to the game server of a café to update data. In this way, game players
inside the café will not be affected.
Min. & Max. Rate:
The minimum bandwidth: The rule is to guarantee minimum available
(Kbit/Sec)
bandwidth.
The maximum bandwidth: This rule is to restrict maximum available
bandwidth. The maximum bandwidth will not exceed the limit set up under
this rule.
Attention! The unit of calculation used in this rule is Kbit. Some software
indicates download/upload speed by the unit KB. 1KB = 8Kbit.
84
Multi-WAN Router
Bandwidth
Sharing total bandwidth with all IP addresses: If this option is selected, all IP
Assign Type:
addresses or Service Ports will share the bandwidth range (from minimum to
maximum bandwidth).
Assign bandwidth for each IP address: If this option is selected, every IP or
Service Port in this range can have this bandwidth (minimum to maximum.).
For example, If the rule is set for the IP of each PC, the IP of each PC will have
the same bandwidth.
Attention: If “Share-Bandwidth” is selected, be aware of the actual usage
conditions and avoid an improper configuration that might cause a malfunction
of the network when the bandwidth is too small. For example, if users do not
want an FTP to occupy too much bandwidth, users can select the
“Share-Bandwidth Mode”, so that no matter how much users use FTPs to
download information, the total occupied bandwidth is fixed.

QoS rules will be executed from the bottom of the list to the top of the list. In
other words, the lower down the list, the higher the priority of execution. Users
can arrange the sequence according to their priorities. Usually the service
ports which need to be restricted, such as BT, e-mule, etc., will be moved to
the bottom of the list. The rules for certain IP addresses would then be moved
upward.

Priority Control:
The Router will distribute the bandwidth as 60% (the highest) and 10% (the lowest). If you set the service
port 80 as “High” priority, the router will give 60% bandwidth to the port 80. In the other hand, if you give the
port 21 as “Low” priority, the device will only give it 10% bandwidth. The remained 30% bandwidth will be
shared by the other service.

8.2 Session control
Session management controls the acceptable maximum simultaneous sessions 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 sessions. Setting up proper limitations on sessions can
effectively control the sessions 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
session requests, session control will restrict that as well.

8.3 Hardware Optimization (Future Feature)
This GIGABIT flagship router not only provides high processing performance but also launches
“hardware optimization’ function for bandwidth control and traffic prioritization.
The main purpose is to
process the bandwidth functions through hardware design, which can accerlate and prioritize the traffic
distribution and usage without wasting CPU and system resources. Hardware optimization will speed up the
router processing, carry huge connection sessions and PCs, and provide stable and excellent network
environment.
Service Optimization:
Service ports that online games and video softwares will be the highest priority. Router can process these
games or videos traffic in first priority. In this way, users can play games or watch videos fluently without
disconnection even when the traffic is full.

technology. The Firewall operates mainly at the network layer. By
executing the dynamic authentication for each connection, it will also
perform an alarming function for application procedure. Meanwhile, the
packet authentication firewall may decline the connections which use
non-standard communication protocol.
DoS (Denial of Service):
This averts DoS attacks such as SYN Flooding, Smurf, LAND, Ping of
Death, IP Spoofing and so on.
Block WAN request:
If set as Enabled, then it will shut down outbound ICMP and abnormal
packet responses in connection. If users try to ping the WAN IP from
the external, this will not work because the default value is set as
activated in order to decline the outbound responses.
Remote Management:
To enter the device web- based UI by connecting to the remote
Internet, this feature must be activated. In the field of remote browser
IP, a valid external IP address (WAN IP) for the device should be filled
in and the modifiable default control port should be adjusted (the
default is set to 80, modifiable).
Multicast Pass Through:
There are many audio and visual streaming media on the network.
Broadcasting may allow the client end to receive this type of packet
message format. This feature is off by default.
Prevent ARP Virus
This feature is designed to prevent the intranet from being attacked by
Attack:
ARP spoofing, causing the connection failure of the PC. This ARP
virus cheat mostly occurs in Internet cafes. When attacked, all the
online computers disconnect immediately or some computers fail to go
online. Activating this feature may prevent the attack by this type of
virus.

Users may turn on/off the setting to permit or forbid any packet to access internet. Users may select to set
different network access rules: from internal to external or from external to internal. Users may set different
packets for IP address and communication port numbers to filter Internet access rules.
Network access rule follows IP address, destination IP address, and IP communications protocol status
to manage the network packet traffic and make sure whether their access is allowed by the firewall.
9.2.1 Default Rule
The device has a user-friendly network access regulatory tool. Users may define network access rules.
They can select to enable/ disable the network so as to protect all internet access. The following describes the
internet access rules:
All traffic from the LAN to the WAN is allowed - by default.
All traffic from the WAN to the LAN is denied - by default.
All traffic from the LAN to the DMZ is allowed - by default.
All traffic from the DMZ to the LAN is denied - by default.
All traffic from the WAN to the DMZ is allowed - by default.
All traffic from the DMZ to the WAN is allowed - by default.
Users may define access rules and do more than the default rules. However, the following four extra
service items are always on and are not affected by other user-defined settings.
* HTTP Service (from LAN to Device) is on by default (for management)
* DHCP Service (from LAN to Device) is set to on by default (for the automatic IP retrieval)
* DNS Service (from LAN to Device) is on by default (for DNS service analysis)
* Ping Service (from LAN to Device) is on by default (for connection and test)

10.1 DMZ Host/ Port Range Forwarding
11.1.1 DMZ Host
When the NAT mode is activated, sometimes users may need to use applications that do not support
virtual IP addresses such as network games. We recommend that users map the device actual WAN IP
addresses directly to the Intranet virtual IP addresses, as follows:
If the “DMZ Host” function is selected, to cancel this function, users must input "0” in the following “DMZ
Private IP”. This function will then be closed.

11.1.2 Port Range Forwarding
Setting up a Port Forwarding Virtual Host: If the server function (which means the server for an
110
Multi-WAN Router
external service such as WWW, FTP, Mail, etc) is contained in the network, we recommend that users use
the firewall function to set up the host as a virtual host, and then convert the actual IP addresses (the
Internet IP addresses) with Port 80 (the service port of WWW is Port 80) to access the internal server
directly. In the configuration page, if a web server address such as 192.168.1.50 and the Port 80 has been
set up in the configuration, this web page will be accessible from the Internet by keying in the device actual
IP address such as, http://211.243.220.43.
At this moment, the device actual IP will be converted into “192.168.1.50” by Port 80 to access the web
page.

10.3 Routing
In this chapter we introduce the Dynamic Routing Information Protocol and Static Routing Information
Protocol.
115
Multi-WAN Router
10.3.1 Dynamic Routing
The abbreviation of Routing Information Protocol is RIP. There are two kinds of RIP in the IP
environment – RIP I and RIP II. Since there is usually only one router in a network, ordinarily just Static
Routing will be used. RIP is used when there is more than one router in a network, and if an administrator
doesn’t want to assign a path list one by one to all of the routers, RIP can help refresh the paths.
RIP is a very simple routing protocol, in which Distance Vector is used. Distance Vector determines
transmission distance in accordance with the number of routers, rather than based on actual session speed.
Therefore, sometimes it will select a path through the least number of routers, rather than through the fastest
routers.
Working Mode:
Select the working mode of the device: NAT mode or Router
mode.
RIP:
Click “Enabled” to open the RIP function.
Receive RIP versions:
Use Up/Down button to select one of “None,
, RIPv1,
, RIPv2,
,
Both RIPv1 and v2” as the “TX” function for transmitting dynamic
RIP.
Transmit RIP versions:
Use Up/Down button to select one of “None,
,RIPv1,
,
RIPv2-Broadcast,
,RIPv2-Multicast” as the “RX” function for
receiving dynamic RIP.

10.4 One to One NAT
As both the device and ATU-R need only one actual IP, if ISP issued more than one actual IP (such as
eight ADSL static IP addresses or more), users can map the remaining real IP addresses to the intranet PC
virtual IP addresses. These PCs use private IP addresses in the Intranet, but after having One to One NAT
mapping, these PCs will have their own public IP addresses.
For example, if there are more than 2 web servers requiring public IP addresses, administrators can map
several public IP addresses directly to internal private IP addresses.
Example:Users have five available IP addresses - 210.11.1.1~5, one of which, 210.11.1.1, has been
configured as a real IP for WAN, and is used in NAT. Users can respectively configure the other four real IP
addresses for Multi-DMZ, as follows:
210.11.1.2
192.168.1.3
210.11.1.3
192.168.1.4
210.11.1.4
192.168.1.5

11.6 High Availability
High Availability is adopted in the network that requires fault tolerance and backup mechanism. Two
similar devices are used to be the backup for each other. One of these devices is employed for major network
transmitting, and the other redundant device will take over when the master device fails to assure that network
transmitting and services never break down. Therefore, administrators will have more opportunity and time to
deal with the master device problems.
Besides general HA, Qno also provides advanced HA function that enables two devices to operate
simultaneously. It brings full cost efficiency without making another device idle. It does not have to be the
same model. All of Qno devices which support HA can achieve the function.
High Availability
Enable: Activate HA function.
Disable: Disable HA function.
Mode
(1) Hardware Backup Mode
It is the general backup mode. The master device takes responsibility of network
transmitting and the other one is set as idle. When the master device fails
transmitting, it will send out the message to the idle device for taking over network
transmitting immediately.
143
Multi-WAN Router
(2) Two devices are operating simultaneously
Two devices operate outbound linking simultaneously, but they are still separated as
Master device and Backup device. In normal situation, Master device is major DHCP
IP issuer, and Backup device will disable DHCP issuing automatically. When Master
device fails transmitting, the Backup device will take over all outbound links and
enable DHCP server to provide IP addresses.
Following is the description of the two different modes.
Hardware Backup
※ Operation-Master Mode
Status
Status of the backup device
Indicates the master device will operate for all outbound links. When
the master device fails transmitting, the backup device will take over.
“Status- Normal” indicates the device operates well.
Indicates status of backup device. If the status is normal,
administrators can login the device remotely to manage. (Remote
Management should be enabled).
“Status- Abnormal” indicates the backup device can not be detected or
does exist, and need to inspect the backup device actual status.
144
Multi-WAN Router
Operation-Backup Mode
Indicates the backup device will take over when the master fails
transmitting. WAN and LAN IP setting in backup device should be the
same as those of master device. The backup device should not be in
charge of network transmitting and DHCP server.
※
If the original LAN IP addresses are issued by Master
device, DHCP server setting of Backup device should be the
same as Master device. The Backup device can keep DHCP
functioning and there will be no LAN disconnection.
LAN IP of the backup device
Input LAN IP of Master mode, which is backed up.
MAC Address of the backup
Input Master device MAC address, which is backed up.
device:
Status
“Status- Normal” indicates the status is idle. Master device operates
normally.
“Status- Backup” indicates the device takes over all the network
transmitting. The status will return to “Normal” when Master device
boots normally and send a message to the backup device. Then, the
status will return to Normal, which the backup device remains idle.
Two devices are operating simultaneously:
145
Multi-WAN Router
Operation-Master Mode
Besides operating network with another device, Master device is also
the DHCP server to issue LAN IP addresses. Although Slave device
also supports outbound linking, its DHCP server is disabled.
WAN Backup
(The Checked WANs are not
The checked WANs will works in the other device. For an example, if
WAN1 and WAN2 work in this device, and WAN3 and WAN4 work in
working in this device.)
the other device, WAN3 and WAN4 should be checked.
LAN Gateway Backup
Input LAN IP of Slave device. The IP should be different from LAN IP
of Master device.
MAC Address of the backup device
Input LAN MAC of Slave device. It should be different from LAN MAC
of Master device.
Status
“Status-Normal” means both two devices operate normally.
“Status-Backup” indicates Slave mode has problems, and the device
enables backup to take over WAN
146
Multi-WAN Router
Operation-Slave Mode
Although working with master device, Backup device’s DHCP server
is disabled. LAN users need to transmit traffic through the WAN on
Slave device. You should add LAN IP of Slave device into Master
device DHCP server default gateway, which is DHCP server IP
address.
For example, if the DHCP server’s IP of Master device is
192.168.1.1, and the subnet mask is 255.255.255.0, Salve device
should be in the same subnet, ex. 192.168.1.2.
WAN Backup
The checked WANs will works in another device. For an example, if
(The Checked WANs are not
WAN1 and WAN2 work in this device, and WAN3 and WAN4 work in
working in this device.)
another, WAN3 and WAN4 should be checked.
LAN Gateway Backup
Input the LAN IP of Master device. It should be different from Slave
device’s IP. (Must be in the same subnet.)
MAC Address of the backup device
Input the LAN MAC of Master device. It should be different from Salve
device’s LAN MAC.
Status
“Status-Normal” indicates both devices work normally;
“Status-Backup” indicates the Backup device is enabled for backing
up Master device to take over WAN connection and DHCP issuing
function.

12.5 IP/ Port Statistic
The device allows administrators to inquire a specific IP (or from a specific port) about the addresses
that this IP had visited, or the users (source IP) who used this service port. This facilitates the identification
of websites that needs authentication but allows a single WAN port rather than Multi-WANs. Administrators
may find out the destination IP for protocol binding to solve this login problem. For example, when certain
port software is denied, inquiring about the IP address of this specific software server port may apply this
feature. Moreover, to find out BT or P2P software, users may select this feature to inquire users from the
port.
Specific IP Status:
Enter the IP address that users want to inquire, and then the entire destination IP connected to remote
devices as well as the number of ports will be displayed.
Specific Port Status:
Enter the service port number in the field and IP that are currently used by this port will be displayed.

Appendix II: Troubleshooting
(1) Shock Wave and Worm Virus Prevention
Since many users have been attacked by Shock Wave and Worm viruses recently, the internet
transmission speed was brought down and the Session bulky increase result in the massive processing
load of the device. The following guides users to block this virus' corresponding port for prevention.
a. Add this TCP135-139, UDP135-139 and TCP445 Port.
b. Use the "Access Rule" in the firewall and set to block these three ports.
173
Multi-WAN Router
Use the same method to add UDP [UDP135~139] and TCP [445~445] Ports.
c. Enhance the priority level of these three to the highest.

(2) Block QQLive Video Broadcast Setting
QQLive Video broadcast software is a stream media broadcast software. Many clients are bothered by
the same problem: When several users apply QQLive Video broadcast software, a greater share of the
bandwidth is occupied, thus overloading the device. Therefore, the device responds more slowly or is
paralyzed. If the login onto the QQLive Server is blocked, the issue can be resolved. The following relates to
Qno products and provides users with solutions by introducing users how to set up the device.
a). Log into the device web- based UI, and enter “Firewall -> Access Rule”.
b). Click "Add New Rule" under "Access Rule" page. Select "Deny" in "Action" under the "Service”
rule setting, followed by the selection of "All Traffic [TCP&UDP/1~65535]" from
"the service" and select
"Any" for Interface, "Any" for source IP address (users with relevant needs may select either "Single" or
"Range" to block any QQLive login by using one single IP or IP range), followed by the selection of
"Single" of the "Dest. IP and enter the IP address as 121.14.75.155" for the QQLive Server (note that
there are more than one IP address for QQLive server. Repeated addition may be needed). Lastly, select
"Always" under the Scheduling setting so that the QQLive Login Time can be set. (If necessary, specific
time setting may be undertaken). Click "Apply" to move to the next step.
c). Input the following IP address in Dest. IP repeatedly.

(3) ARP Virus Attack Prevention
1.
ARP Issue and Information
Recently, many cyber cafes in China experienced disconnection (partially or totally) for a short period of
time, but connection is resumed quickly. This is caused by the clash with MAC address. When virus-contained
MAC mirrors to such NAT equipments as host devices, there is complete disconnection within the network. If
it mirrors to other devices of the network, only devices of this affected network have problems. This happens
mostly to legendary games especially those with private servers. Evidently, the network is attacked by ARP,
which aims to crack the encryption method. By doing so, they hackers may intercept the packet data and user
information through the analysis of the game's communication protocol. Through the spread of this virus, the
detailed information of the game players within the local network can be obtained. Their account and
information are stolen. The following describes how to prevent such virus attack.
First, let us get down to the definition of ARP (Address Resolution Protocol). In LAN, what is actually
transmitted is "frame", in which there is MAC address of the destination host device. So-called “Address
Analysis” refers to the transferring process of the target IP address into the target MAC address before the
host sends out the frame. The basic function of ARP protocol aims to inquire the MAC address of the target
equipment via the IP address of the target equipment so as to facilitate the communications.
The Working Principle of ARP Protocol: Computers with TCP/IP protocol have an ARP cache, in which
the IP address corresponds to the MAC address (as illustrated).
IP
MAC
192.168.1.1
00-0f-3d-83-74-28
192.168.1.2
00-aa-00-62-c5-03
192.168.1.3
03-aa-01-75-c3-06
……
……
For example, host A (192.168.1.5) transmits data to Host B (192.168.1.1) .Transmitting data, Host A
searches for the destination IP address from the ARP Cache. If it is located, MAC address is known. Simply fill
in the MAC address for transmission. If no corresponding IP address is found in ARP cache, Host A will send
a broadcast. The MAC address is “FF.FF.FF.FF.FF.FF,” which is to inquire all the host devices in the same
network session about “What is the MAC address of “192.168.1.1"? Other host devices do not respond to the
ARP inquiry except host device B, which responds to host device A when receiving this frame: “The MAC
address of 192.168.1.1 is 00-aa-00-62-c6-09”. So Host A knows the MAC address of Host B, and it can send
177
Multi-WAN Router
data to Host B. Meanwhile, it will update its ARP cache.
Moreover, ARP virus attack can be briefly described as an internal attack to the PC, which causes trouble
to the ARP table of the PC. In LAN, IP address was transferred into the second physical address (MAC
address) through ARP protocol. ARP protocol is critical to network security. ARP cheating is caused by fake IP
addresses and MAC addresses, and the massive ARP communications traffic will block the network. The
MAC address from the fake source sends ARP response, attacking the high-speed cache mechanism of ARP.
This usually happens to the cyber cafe users. Some or all devices in the shop experience temporal
disconnection or failure of going online. It can be resolved by restarting the device; however, the problem
repeats shortly after. Cafe Administrators can use arp –a command to check the ARP table. If the device IP
and MAC are changed, it is the typical symptom of ARP virus attack.
Such virus program as PWSteal. lemir or its transformation is worm virus of the Trojan programs affecting
Windows 95/ 98/ Me/ NT/ 2000/ XP/ 2003. There are two attack methods affecting the network connection
speed: cheat on the ARP table in the device or LAN PC. The former intercepts the gateway data and send
ceaselessly a series of wrong MAC messages to the device, which sends out wrong MAC address. The PC
thus cannot receive the messages. The later is ARP attack by fake gateways. A fake gateway is established.
The PC which is cheated sends data to this gateway and doesn't go online through the normal device. From
the PC end, the situation is "disconnection“.
For these two situations, the device and client setup must be done to prevent ARP virus attack, which is
to guarantee the complete resolution of the issue. The device selection is advised to take into consideration
the one with anti-ARP virus attack. Qno products come squarely with such a feature, which is very
user-friendly compared to other products.
2.
ARP Diagnostic
If one or more computers are affected by the ARP virus, we must learn how to diagnose and take
appropriate measures. The following is experience shared by Qno technical engineers with regard to the ARP
prevention.
Through the ARP working principle, it is known that if the ARP cache is changed and the device is
constantly notified with the series of error IP or if there is cheat by fake gateway, then the issue of
disconnection will affect a great number of devices. This is the typical ARP attack. It is very easy to judge if
there is ARP attack. Once users find the PC point where there is problem, users may enter the DOS system to
conduct operation, pining the LAN IP to see the packet loss. Enter the ping 192.168.1.1 (Gateway IP address)
as illustrated.
178
Multi-WAN Router
If there are cases of packet loss of the ping LAN IP and lf later there is connection, it is possible that the
system is attacked by ARP. To verify the situation, we may judge by checking ARP table. Enter the ARP -a
command as illustrated below.
It is found that the IP of 192.168.1.1 and 192.168.252 points to the same MAC address as
00-0f-3d-83-74-28. Evidently, this is a cheat by ARP.
3.
ARP Solution
Now we understand ARP, ARP cheat and attack, as well as how to identify this type of attack. What
comes next is to find out effective prevention measures to stop the network from being attacked. The general
solution provided by Qno can be divided into the following three options:
a) Enable “Prevent ARP Virus Attack”:
Enter the device IP address to log in the management webpage of the device. Enter ”Firewall-> General”
and find the option "Prevent ARP Virus Attack" to the right of the page. Click on the option to activate it and
click "Apply" at the bottom of the page (see illustrated).
179
Multi-WAN Router
b) Bind the Gateway IP and MAC address for each PC
This prevents the ARP from cheating IP and its MAC address. First, find out the gateway IP and MAC
address on the device end.
On every PC, start or operate cmd to enter the dos operation. Enter arp –s 192.168.1.1 0a-0f-d4-9e-fb-0b
so as to finish the binding of pc01 as illustrated.
For other host devices within the network, follow the same way to enter the IP and MAC address of the
corresponding device to complete the binding work. However, if this act restarts the computer, the setting will
be cancelled. Therefore, this command can be regarded as a batch of processing documents placed in the
activation of the operation system. The batch processing documents can be put in this way:
@echo off
arp -d
180
Multi-WAN Router
arp -s Router LAN IP
Router LAN MAC
For those internal network attacked by Arp, the source must be identified. Method: If the PC fails to go
online or there is packet loss of ping, in the DOS screen, input arp –a command to check if the MAC address
of the gateway is the same with the device MAC address. If not, the PC corresponding to the MAC address is
the source of attack.
Solutions for other device users are to make a two-way binding of the IP address and MAC address from
both of the PC and device ends in order to carry out the prevention work. However, this is more complicated
because the search for the IP and address and MAC increases the workload. Moreover, there is greater
possibility of making errors during the operation.
c) Bind the IP/MAC Address from Device End:
Enter “Setup” under DHCP page. On the down right corner of the screen, there is “IP and MAC Binding,”
where users may create IP and MAC binding. On “Enabled,” click on “√” and select “Add to List.” Repeat
these steps to add other IP addresses and MAC binding, followed by clicking “Apply” at the bottom of the
page.
181
Multi-WAN Router
After an item is added to the list, the corresponding message will be displayed in the white block on the
bottom. However, such method is not recommended because the inquiry of IP/MAC addresses of all hosts
creates heavy workload. Another method to bind IP and MAC is more recommended because of easy
operation, reducing workload and time efficiency. It is described in the following.
Enter “Setup” under the DHCP page and look for IP and MAC binding. On the right, there is an option of
"Show new IP user" and click to enter.
182
Multi-WAN Router
Click to display IP and MAC binding list dialog box. In this box, the unbinding IP and MAC address
corresponding to the PC are displayed. Enter the "Name" of the computer and click on "Enabled" with the
display of the “√” icon and push the option on the top right corner of the screen to confirm.
Now the bound options will display on the IP and MAC binding list (as illustrated in Figure 5) and click
"Apply” to finish binding.
183
Multi-WAN Router
Though these basic operations can help solve the problem but Qno's technical engineers suggest that
further measures should be taken to prevent the ARP attack.
1.
Deal with virus source as well as the source device affected by virus through virus killing and the
system re-installation. This operation is more important because it solves the source PC which is attacked by
ARP. This can better shelter the network from being attacked.
2. Cyber café administrators should check the LAN virus, install anti-virus software (Ginshan Virus/Reixin
must update the virus codes) and conduct virus scanning for the device.
3. Install the patch program for the system. Through Windows Update, the system patch program (critical
update, security update and Service Pack)
4. Provide system administrators with a sophisticated and strong password for different accounts. It
would be best if the password consists of a combination of more than 12 letters, digits, and symbols. Forbid
184
Multi-WAN Router
and delete some redundant accounts.
5. Frequently update anti-virus software (virus data base), and set the daily upgrade that allows regular
and automatic update. Install and use the network firewall software. Network firewall is important for the
process of anti-virus. It can effectively avert the attack from the network and invasion of the virus. Some users
of the pirate version of Windows cannot install patches successfully. Users are advised to use network firewall
and other measures for protection.
6. Close some unnecessary services and some unnecessary sharing (if the condition is applicable),
which includes such management sharing as C$ and D$. Single device user can directly close Server service.
7. Do not open QQ or the link messages sent by MSN online chatting tools in a causal manner. Do not
open or execute any strange, suspicious documents, and procedures such as the unknown attachment
enclosed in E-mail and plug-in.
4.
Summary
ARP attack prevention is a serious and long-term undertaking. The above methods can basically resolve
the network problems caused by ARP virus attack. Moreover, clients who adopted similar methods witness
good results. However, it is important that network administrators pay special attention to this problem rather
than overlooking the issue. It is suggested that the above measures can be adopted to prevent ARP attack,
reduce the damage, enhance the work efficiency, and minimize economic loss.
