I. Introduction

Security QoS Router (referred as Security QoS Router hereby) is a business level security router that efficiently integrates new generation multiple WAN-port devices. It meets the needs of medium enterprises, internet cafés, campus, dorm and communities, etc. Apart from its internet connectivity that suits the broadband market, Security QoS Router has a built-in QoS and VLAN switching board which enables it to fulfill most enterprises and internet cafes firewall needs.

Security QoS Router has 2 10/100 Base-T/TX Ethernets (RJ45) WAN ports. These WAN ports can support auto load balance mode, exclusive mode (remaining WAN balance), and strategy 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, port binding, static routing, dynamic routing, NAT, one to one NAT, PAT, MAC Clone, as well as DDNS. As for WAN ports including one DMZ, they support 2 10/100 Base-T/TX Ethernet (RJ45) ports and provide the features of Microsoft UPnP, VLAN, Multi Subnet, and transparent bridge. Internet IP addresses can also be used in intranet.

To fulfill the requirement of a highly secure and integrated firewall, Security QoS Router has a 64-bit embedded hardware acceleration, high-speed, high-efficiency processor. With high processing speed, plusing high standard SDRAM and Flash, Security QoS Router brings users super networking efficiency. Its processing speed and capacity are almost equal to those of expensive enterprise-level Security QoS Routers. This is why the device is so popular with modern enterprises.

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

Through web- based UI, Security QoS 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 completing OS（Operating System） management, school and business internet management will be clearly improved. Security QoS Router offers various on-line SysLog records. It supports on-line management setup tools; it makes network's setting up easy to understand. It also reinforces the management of network access rules, and all other network services.

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

6.2 Multi- WAN Setting

When you have multiple WAN gateways, you can use Traffic Management and Protocol Binding function to fulfill WAN road balancing, so that we can have highest network bandwidth efficiency.

SSeeccuurriittyy QQooSS RRoouutteer

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.

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

SSeeccuurriittyy QQooSS RRoouutteer

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.

Specify WAN Binding 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.

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

SSeeccuurriittyy QQooSS RRoouutteer

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.

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.

Apply:

Click “Apply” to save the modification.

SSeeccuurriittyy QQooSS RRoouutteer

Cancel:

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.

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.

SSeeccuurriittyy QQooSS RRoouutteer

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.

SSeeccuurriittyy QQooSS RRoouutteer

Click “Advanced Function” to enter the setting window：

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 the first connection goes to. If the destination IP is in the same Class B range, the connection will go

through with the same WAN IP based on the first time learning.

SSeeccuurriittyy QQooSS RRoouutteer

User Define Dis. Or Port Auto

Binding：

Indicates that the intranet IP will connect through the same WAN IP 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：

(As following figure)

When any intranet IP connects with TCP443 port or any destination (0.0.0.0 to 0 represents any destination),

Multi-WAN Router

SSeeccuurriittyy QQooSS RRoouutteer

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 IP-

192.168.100.1 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 Service Detection 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”.

SSeeccuurriittyy QQooSS RRoouutteer

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.

SSeeccuurriittyy QQooSS RRoouutteer

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). Therefore, in this mode, we recommend assigning one of the connections to the first WAN. When other WANs (WAN2) 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.

6.2.3 Protocol Binding

Interface Configuration

Router allows maximum two WAN interface, the bandwidth and real connection of every WAN will impact the load balance mechanism; therefore you need to set the Bandwidth and the Network service detection by each WAN Port correctly.

In “WAN Setting”, click “Edit” to enter the WAN port configuration.

SSeeccuurriittyy QQooSS RRoouutteer

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.

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) 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.

SSeeccuurriittyy QQooSS RRoouutteer

Service:

This is to select the Binding Service Port to be activated. The default (such as ALL-TCP&UDP 0~65535, WWW 80~80, FTP 21 to 21, etc.) can be selected from the pull-down option list. The default Service is All 0~65535. Option List for Service Management: Click the button to enter the Service Port configuration page to add or remove default Service Ports on the option list.

Source IP:

Users can assign packets of specific Intranet virtual IP to go through a specific WAN port for external connection. In the boxes here, input the Intranet virtual IP address range; for example, if 192.168.1.100~150 is input, the binding range will be 100~150. If only specific Service Ports need

to be designated, while specific IP designation is not necessary, input “0” in

the IP boxes.

Dest. IP:

In the boxes, input an external static IP address. For example, if

SSeeccuurriittyy QQooSS RRoouutteer

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?

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.

SSeeccuurriittyy QQooSS RRoouutteer

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.

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,

SSeeccuurriittyy QQooSS RRoouutteer

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, 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

SSeeccuurriittyy QQooSS RRoouutteer

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 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.

SSeeccuurriittyy QQooSS RRoouutteer

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 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 “211.1.1.160.1.1.1 ~ 60,254,254,254”. Select WAN21 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. Intranet Configuration

This chapter introduces how to configure ports and understand how to configure intranet IP addresses.

7.1 Port Management

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.

DisabledPort：

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”.

SSeeccuurriittyy QQooSS RRoouutteer

Speed Status：

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.

SSeeccuurriittyy QQooSS RRoouutteer

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.

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.

SSeeccuurriittyy QQooSS RRoouutteer

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.

SSeeccuurriittyy QQooSS RRoouutteer

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.

WINS Server：

Input the IP address of WINS.

Apply：

Click “Apply” to save the network configuration modification.

Cancel：

Click “Cancel" to leave without making any changes.

SSeeccuurriittyy QQooSS RRoouutteer

7.4 DHCP Status

This is an indication list of the current status and setup record of the DHCP server. The indications are for

the administrator’s reference when a network modification is needed.

DHCP Server：

This is the current DHCP IP.

Dynamic IP Used：

The amount of dynamic IP leased by DHCP.

Static IP Used：

The amount of static IP assigned by DHCP.

DHCP Available：

The amount of IP still available in the DHCP server.

Total：

The total IP which the DHCP server is configured to lease.

SSeeccuurriittyy QQooSS RRoouutteer

Host Name：

The name of the current computer.

IP Address：

The IP address acquired by the current computer.

MAC Address：

The actual MAC network location of the current computer.

Client Lease Time：

The lease time of the IP released by DHCP.

Delete：

Remove a record of an IP lease.

DNS Local Database (Feature)

Normally, DNS sever will be directed to ISP DNS server or internal self- defined DNS server.

Qno router also provides “easy” self- defined DNS services, called “DNS Local Database”, which

can map website host domain names and the corresponding IP addresses.

Host Domain Name

Enter the website host domain name. i.e. www.google.com

IP Address

Enter the corresponding IP address of the host domain above.

SSeeccuurriittyy QQooSS RRoouutteer

Add to Llist

Add the items into the list below.

Delete selected item

Delete the items chosen.

※ Note!

(1) Users MUST enable DCHP server service to enable DNS local database. (2) Users must set DHCP server DNS IP address as the router LAN IP. For example, LAN is 10.10.10.1, as shown in the following figure.

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.

SSeeccuurriittyy QQooSS RRoouutteer

(1) System Tool => Diagnostic => DNS Name Lookup

(2) Enter tw.yahoo.com for lookup.

(3) The IP is 10.10.10.199, confirming the corresponding IP in DNS local database.

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.

SSeeccuurriittyy QQooSS RRoouutteer

There are two methods for setting up this function：

(1)、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：

SSeeccuurriittyy QQooSS RRoouutteer

(2)、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.

SSeeccuurriittyy QQooSS RRoouutteer

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.

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.

SSeeccuurriittyy QQooSS RRoouutteer

8.1 Bandwidth Management

SSeeccuurriittyy QQooSS RRoouutteer

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 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.

SSeeccuurriittyy QQooSS RRoouutteer

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.

SSeeccuurriittyy QQooSS RRoouutteer

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.

SSeeccuurriittyy QQooSS RRoouutteer

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 ~ 149”. The rule will control IP addresses from

192.168.1.100 to 149. 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 C.

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.

SSeeccuurriittyy QQooSS RRoouutteer

Bandwidth sharing：

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.

Delete selected items：

Remove the rules selected from the Service List.

Show Table： Display all the Rate Control Rules users made for the bandwidth. Click

“Edit” to modify.

Apply： Click “Apply” to save the configuration

Cancel： Click “Cancel" to leave without making any change.

Show Table：

Below to the left is “Show Table” button. Click it, a dialog as below will pop up. Users can select “Rule” or

“Interface” button to display the configured rules. Click “Refresh” to renew the table and “Close” to close it. For

reconfiguring the rule, click “Edit”.

SSeeccuurriittyy QQooSS RRoouutteer

Example 1. How to set up the maximum download speed to 50 Kbit for the FTP protocol on all WAN

interfaces ?

Please refer to the following as a setup example. Click before both WAN1 and WAN2; then choose "FTP

[TCP/21~21]" in Service; for IP Address, put your LAN IP range (e.g.192.168.1.1~254); in "Direction" part, open the

dropdown box and choose Downstream. Import 2Kbit/Sec in Mini. Rate, which guarantees the minimum bandwidth

for FTP downloading. And import 50Kbit/Sec in Max. Rate for a maximum limitation. Choose “Share total bandwidth

with all IP addresses” in “Bandwidth sharing” method, which means that the whole LAN users share a maximum

50Kbits/Sec download speed on the FTP protocol no matter how many users are using in intranet. Click “Enable” and

“Add to list”, then this rule is successfully added.

SSeeccuurriittyy QQooSS RRoouutteer

Example 2. How to set up the maximum download speed of each WAN to 512Kbit/Sec for each LAN user?

One by one IP to set up?

No need to set up one by one. Below is the example. Click both WAN1 and WAN2; then choose “No Check

Port[TCP&UDP /0~0” in Service; for IP Address, put your LAN IP range (e.g.192.168.1.1~254); in "Direction" part, open

the dropdown box and choose Downstream. Import 2Kbit/Sec in Mini. Rate, which guarantees the minimum

bandwidth. And import 512Kbit/Sec in Max. Rate for a maximum limitation. Choose “Assign bandwidth for each IP

address” in “Bandwidth sharing” method, which ensures each IP a minimum 2Kbits/Sec download speed . Click

“Enable” and “Add to list”, then this rule is successfully added.

Attention! The action rule priority of the QoS bandwidth management is from the bottom to the top rule, therefore

you have to remove the rule what you want to implement first to the bottom.

SSeeccuurriittyy QQooSS RRoouutteer

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.

SSeeccuurriittyy QQooSS RRoouutteer

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.

8.3 Smart QoS

The smart QoS function enables the administrators to constrain the bandwidth occupied automatically without any configuring.

Enabled QoS：

Choose to apply QoS function.

When the usage of any WAN’s bandwidth is over than___%, Enable Smart QoS

Input the required rate value into the column. The default is 60%.

Each IP’s upstream bandwidth threshold (for all WAN)：

Input the max. upstream rate for intranet IPs.

Each IP’s downstream bandwidth threshold (for all WAN) ：

Input the max. downstream rate for intranet IPs.

If any IP’s bandwidth is over maximum threshold, its maximum bandwidth will remain：

When any IP uses more bandwidth than the above upstream or downstream settings, the IP will be restricted for the following upstream or downstream bandwidth settings.

Enabled Penalty Mechanism：

After choosing “Enabled Penalty Mechanism”, the device will enable the penalty conditions internally. When the IP still uses more upstream or downstream bandwidth than the setting, the device will execute the penalty conditions automatically.

Show Penalty IP：

The IPs which are under penalty mechanism will be shown on the list.

SSeeccuurriittyy QQooSS RRoouutteer

Scheduling：

If “Always” is selected, the rule will be executed around

the clock.

If “From…” is selected, the rule will be executed

according to the configured time range. For example, if the time control is from Monday to Friday, 8:00am to 6:00pm, users can refer to the following figure to set up the rule.

SSeeccuurriittyy QQooSS RRoouutteer

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.

SSeeccuurriittyy QQooSS RRoouutteer

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.

SSeeccuurriittyy QQooSS RRoouutteer

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.

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)

SSeeccuurriittyy QQooSS RRoouutteer

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.
