I. Introduction

Enterprise Multi-WAN VPN QoS Router (referred as VPN Router hereby) is a business
level security router that efficiently integrates new generation multiple WAN-port devices. It
meets the needs of both medium and large-scale enterprises, internet cafés, and
communities, etc. Apart from its internet connectivity that suits the broadband market, VPN
Router has a built-in 10/100Mbps QoS and VLAN switching board which enables it to fulfill
most enterprise and internet cafe firewall needs.

VPN Router has 2-4 10/100 Base-T/TX Ethernets (RJ45) WAN ports. These WAN ports
can support auto load balance mode, exclusive mode (remaining WAN balance), and stategy
routing mode for high-efficiency network. They offer super flexibility for network set-up.
Moreover, these WAN ports also support DHCP, fixed IP, PPPoE, transparent bridge, VPN
connection, port binding, static routing, dynamic routing, NAT, one to one NAT, PAT, MAC
Clone, as well as DDNS. As for LAN ports including one DMZ, they support 10/100 Base-T/TX
Ethernet (RJ45) and provide the features of virtual route, Microsoft UPnP, VLAN, Multi Subnet,
and transparent bridge mode. Internet IP addresses can also be used in intranet.

To fulfill the requirement for a highly secure and integrated firewall, VPN Router has a
high-speed, high-efficiency four-core Intel IXP processor embedded. With high processing
speed, plusing high standard SDRAM and Flash, VPN Router brings users super networking
efficiency. Its processing speed and capacity are almost equal to those of expensive
enterprise-level VPN Routers. This is why the device is so popular with modern enterprises.

In addition to internet connectability, for the broadband market, VPN Router has the
function of VPN virtual network connection. It is equipped with a virtual private network
hardware acceleration mode which is widely used in modern enterprises, and offers full VPN
functionality.

Qno is a supporter of the IPSec Protocol. IPSec VPN provides DES, 3DES, AES-128
encryption, MD5, SH1 certification, IKE Pre-Share Key, or manual password interchange. VPN
Router also supports aggressive mode. When a connection is lost, VPN Router will
automatically re-connect. In addition, the device features NetBIOS transparency, and
supports IP grouping for connections between clients and host in the virtual private network.

VPN Router offers the function of a standard PPTP server, which is equipped with
connection setting status. Each WAN port can be set up with multiple DDNS at the same time.
It is also capable of establishing VPN connections with dynamic IP addresses.

VPN Router also has unique QVM VPN- SmartLink IPSec VPN. Just input VPN server IP,
user name, and password, and IPSec VPN will be automatically set up. Through VPN Router
exclusive QVM function, users can set up QVM to work as a server, and have it accept other
QVM series products from client ports. QVM offers easy VPN allocation for users; users can do
it even without a network administrator. VPN Router enables enterprises to benefit from VPN
without being troubled with technical and network management problems. The central
control function enables the host to log in remote client computers at any time. Security and
secrecy are guaranteed to meet the IPSec standard, so as to ensure the continuity of VPN
service.

The advanced built-in firewall function enables VPN Router to resist most attacks from
the Internet. It utilizes active detection technology SPI (Stateful Packet Inspection). The SPI
firewall functions mainly within the network by dynamically inspecting each link. The SPI
firewall also has a warning function for the application process; therefore, it can refuse links
to non-standard communication protocols. VPN Router supports network address translation
(NAT) function and routing modes. It makes the network environment more flexible and
easier to manage.

Through web- based UI, VPN Router enables enterprises to have their own network
access rules . To control web access, users can build and edit filter lists. It also enables users
to ban or monitor websites according to their needs. By the filter setting and complete OS
management, school and business internet management will be clearly improved. VPN
Router offers various on-line SysLog records. It supports on-line management setup tools; it
makes setting up networks easy to understand. It also reinforces the management of
network access rules, VPN, and all other network services.

VPN Router fully protects the safety of communication between all offices and branches
of an organization. It helps to free enterprises from increasing hacker intrusion. With an
exclusive independent operation platform, users are able to set up and use a firewall without
professional network knowledge. VPN Router setting up and management can be carried out
through web browsers, such as IE, Netscape, etc.

6.2 Multi- WAN Setting

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 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.

Enterprise Multi-WAN VPN QoS Router

36

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 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.

Enterprise Multi-WAN VPN QoS Router

37

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.

Enterprise Multi-WAN VPN QoS Router

38

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

Item:

To remove selected WANs from the WAN grouping.

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.

Enterprise Multi-WAN VPN QoS Router

39

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.

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.

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.

Enterprise Multi-WAN VPN QoS Router

40

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”.

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

Enterprise Multi-WAN VPN QoS Router

41

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.

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.)

Enterprise Multi-WAN VPN QoS Router

42

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

Bandwidth Configuration

When Auto Load Balance mode is selected, the device will select sessions or IP and the WAN

bandwidth will 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 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. The section refers to QoS configuration. Therefore, it should be set in

QoS page. Please refer to 8.1 QoS bandwidth configuration.

Enterprise Multi-WAN VPN QoS Router

43

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.

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

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.

Interface: Select the WAN for which users want to set up the binding rule.

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?

Enterprise Multi-WAN VPN QoS Router

47

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.

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.

Enterprise Multi-WAN VPN QoS Router

48

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

Enterprise Multi-WAN VPN QoS Router

49

Internet IP addresses). Select WAN1 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 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

Enterprise Multi-WAN VPN QoS Router

50

through WAN1?

As in the figure below, 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 ~ 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

Enterprise Multi-WAN VPN QoS Router

51

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 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.

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.

Enterprise Multi-WAN VPN QoS Router

53

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.

Enterprise Multi-WAN VPN QoS Router

54

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”.

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.

Enterprise Multi-WAN VPN QoS Router

55

7.2 Port Status

Summary：

There are Network Connection Type, Interface, Link Status (Up/Down), Port Activity (Port

Enabled), Priority Setting (High or Normal), Speed Status (10Mbps or 100Mbps), Duplex Status

(half duplex or full duplex), Auto Neg. (Enabled/Disabled), and VLAN.

7.3 IP/ DHCP

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.

Enterprise Multi-WAN VPN QoS Router

58

Dynamic IP：

Client lease Time：

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.

Range Start：

This is to set up a lease time for the IP address which is acquired

by a PC. The default is 1440 minutes (a day). Users can change it

according to their needs. The time unit is minute.

Range End：

This is an initial IP automatically leased by DHCP. It means DHCP

will start the lease from this IP. The default initial IP is

192.168.1.100.

DNS (Domain Name Service)：

This is for checking the DNS from which an IP address has been leased to a PC port.

Input the IP address of this server directly.

DNS (Required) 1：

Input the IP address of the DNS server.

DNS (Optional) 2：

Input the IP address of the DNS server.

WINS：

If there is a WIN server in the network, users can input the IP address of that server

directly.

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：

Enterprise Multi-WAN VPN QoS Router

62

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：

IP & MAC Binding

Enterprise Multi-WAN VPN QoS Router

63

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.

Enterprise Multi-WAN VPN QoS Router

64

Name：

For distinguishing clients, input the name or address of

the 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.

Select All：

Choose all items on the list for binding.

Refresh：

Refresh the list.

Close：

Close the list.

Enterprise Multi-WAN VPN QoS Router

65

7.6 IP Grouping

The function enables users to make the same configuration for a range of continuous IP

addresses in the network. For example, if an IP range (192.168.1.100~192.168.1.110) has been

assigned to a department of a company, we can bind all the IP addresses together and make an

accessing rule configuration for them all at the same time, instead of configuring each IP

respectively, which takes more time and is more prone to error.

IP Group：

Select a group to which the modification is to be made.

Add Group：

Click Add Group to crate a new IP group.

Delete Group：

Delete the chosen IP group.

Group Name：

Input or change the name for the group.

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.

Enterprise Multi-WAN VPN QoS Router

67

8.1 Bandwidth Management

8.1.1 The Maximum Bandwidth provided by ISP

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

Enterprise Multi-WAN VPN QoS Router

68

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.

Enterprise Multi-WAN VPN QoS Router

69

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.

Enterprise Multi-WAN VPN QoS Router

70

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：

(Kbit/Sec)

The minimum bandwidth: The rule is to guarantee minimum

available 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.

Enterprise Multi-WAN VPN QoS Router

71

Bandwidth
Assign Type：

Sharing total bandwidth with all IP addresses: If this option is

selected, all IP 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.

Enable：

Activate the rule.

Add to list：

Add this rule to the list.

Move up & Move

down：

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.

Session Control and Scheduling：

Disabled：

Disable Session Control function.

Single IP cannot

exceed __
session：

This option enables the restriction of maximum external sessions

to each Intranet PC. When the number of external sessions

reaches the limit, to allow new sessions to be built, some of the

existing sessions must be closed. For example, when BT or P2P is

being used to download information and the sessions exceed the

limit, the user will be unable to connect with other services until

either BT or P2P is closed.

Enterprise Multi-WAN VPN QoS Router

75

When single IP
exceed __：

If this function is selected, when the user’s port session reach

the limit, this user will not be able to make a new session for five

minutes. Even if the previous session has been closed, new

sessions 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

IX. Firewall

This chapter introduces firewall general policy, access rule, and content filter settings to

ensure network security.

9.1 General Policy

The firewall is enabled by default. If the firewall is set as disabled, features such as SPI,

DoS, and outbound packet responses will be turned off automatically. Meanwhile, the remote

management feature will be activated. The network access rules and content filter will be

turned off.

Firewall：

This feature allows users to turn on/off the firewall.

SPI (Stateful Packet
Inspection)：

This enables the packet automatic authentication detection

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
Attack：

This feature is designed to prevent the intranet from being

attacked by 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.

Advanced Setting

Packet Type: This device provides three types of data packet
transmission: TCP-SYN-Flood, UDP-Flood and ICMP-Flood.

WAN Threshold: When all packet values from external attack or
from single external IP attack reach the maximum amount (the
default is 15000 packets/Sec and 2000 packets/Sec
respectively), if these conditions above occurs, the IP will be
blocked for 5 minutes ( the default is 5 minutes OBJ 176 ). Users
can adjust the threshold value and the blocking duration to
effectively deal with external attack. The threshold value should
be adjusted from high to low.

LAN Threshold: When all packet values from internal attack or
from single internal IP attack reach the maximum amount (the
default is 15000 packets/Sec and 2000 packets/Sec
respectively), if these conditions above occurs, the IP will be
blocked for 5 minutes (the default is 5 minutes). Users can
adjust the threshold value and the blocking duration to
effectively deal with external attack. The threshold value should
be adjusted from high to low.

Exempted Source IP：

Input the exempted source IP.

Exempted Dest. IP：

9.3 Access Rule

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.

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)

In addition to the default rules, all the network access rules will be displayed as illustrated

above. Users may follow or self- define the priority of each network access rule. The device will

follow the rule priorities one by one, so please make sure the priority for all the rules can suit the

setting rules.
