Parameters
Description
Src/dst
If you want to monitor the source IP of the packets, please select src IP. Otherwise,
please select dst IP.
IP Address
Specify the IP Address that you want to limit the transmit/receive rate.
IP Mask
If you want to limit a subnet, you can specify the subnet mask here.
Protocol
Specify the protocol you want to monitor, it can be TCP / UDP / or IP only.
Start / End Port
Specify the port ranges that you want to monitor. To classify all TCP or UDP packets
within same IP address / mask (regardless of port number) as same rate policy, set 0
to both Start Port and End Port.
Rate / Unit / isByteCount
Specify the rate, unit, and the type of the limitation.

at the bottom of the screen to save the above configurations. You can now configure other advance
sections or start using the router (with the advance settings in place)
2.4.3 Guaranteed / Spare Class QoS
User can first specify maximum WAN total bandwidth and then set bandwidth allocation rules according to two different
classes: Guaranteed or Spared. Rules in Guaranteed class are guaranteed to have specified percentage of WAN Total
bandwidth. At any period of time, if the aggregated bandwidth used by flows in guaranteed class doesn’t exceed total
bandwidth, the spared bandwidth is then available for allocating to the flows in Spared class, according to the percentage
configured.
For example, 192.168.1.1 is guaranteed to have 50Mbps bandwidth if it needs and 192.168.1.2 has 25Mbps guaranteed
on demand. If for a period of time, the aggregated bandwidth used by both hosts is 40Mbps , so only 40% WAN
bandwidth is consumed by Guaranteed class flows, then all other hosts in 192.168.1.0 can compete to use the spared
60Mbps WAN bandwidth. If there exists another LAN on gateway, say, 192.168.2.0/24, then they can only use the rested
bandwidth consumed by guaranteed and spared class.

Parameters
Description
Queue ID
The Queue (Group) ID groups all the connections with the same Queue ID into one
rule and these connections share the same bandwidth in this rule.
Src/Dst
If you want to monitor the source IP of the packets, please select src IP. Otherwise,
please select dst IP.
IP Address
Specify the IP Address that you want to limit the transmit/receive rate.
IP Mask
If you want to limit a subnet, you can specify the subnet mask here.
Protocol
Specify the protocol you want to monitor, it can be TCP / UDP / or IP only.
Start / End Port
Specify the port ranges that you want to monitor. To classify all TCP or UDP packets
within same IP address / mask (regardless of port number) as same rate policy, set 0
to both Start Port and End Port.
Bandwidth allocation policy
Guaranteed or Spare.
Percentage
Input the percentage of total bandwidth that this queue have.
DSCP Marking
Differentiated Services Code Point is a model in which traffic is treated by intermediate
systems with relative priorities based on the type of services. If you want to mark this
Queue to specified DSCP type, enable this option and filled a value in the DSCP value
field.

sections or start using the router (with the advance settings in place)
2.5 NAT
Network Address Translation (NAT) allows multiple users at your local site to access the Internet through a single Public
IP Address or multiple Public IP Addresses. NAT provides Firewall protection from hacker attacks and has the flexibility to
allow you to map Private IP Addresses to Public IP Addresses for key services such as Websites and FTP.

Parameter
Description
2.5.1 Virtual Server
You can have different services (e.g. email, FTP, Web etc.) going to different
service servers/clients in your LAN. The Virtual Server allows you to re-direct a
particular service port number (from the Internet/WAN Port) to a particular LAN
IP address and its service port number.
2.5.2 Special Applications
Some applications require multiple connections, such as Internet games, video
conferencing, Internet telephony and others. In this section you can configure
the router to support these types of applications.
2.5.3 ALG Setting
You can select special applications that need “Application Layer Gateway” to
support here.
2.5.4 UPnP Setting
It allows to Enable or Disable UPnP feature here. After you enable the UPnP
feature, all client systems that support UPnP, like Windows XP, can discover this
router automatically and access the Internet through this router without any
configuration. The NAT Traversal function provided by UPnP can let applications
that support UPnP smoothly connect to Internet sites without any incompatibility
problem due to the NAPT port translation.
2.5.5 Static Routing
You can disable NAT function and setup the routing rules manually.
Click on one of the three NAT selections and proceed to the manual's relevant sub-section.
2.5.1 Virtual Server
Use the Virtual Server function when you want different servers/clients in your LAN to handle different service/Internet
application type (e.g. Email, FTP, Web server etc.) from the Internet. Computers use numbers called port numbers to
recognize a particular service/Internet application type. The Virtual Server allows you to re-direct a particular service port
number (from the Internet/WAN Port) to a particular LAN private IP address and its service port number. (See Glossary
for an explanation on Port number)

Parameters
Description
WAN Port Range
Enter the service (service/Internet application) port number from the Internet that will be
re-directed to the above Private IP address host in your LAN
Note
: Virtual Server function will have priority over the DMZ function if there is a conflict
between the Virtual Server and the DMZ settings.
Server IP Address
This is the LAN client/host IP address that the Public Port number packet will be sent to.
Note:
You need to give your LAN PC clients a fixed/static IP address for Virtual Server
to work properly.
Server Port Range
This is the port number (of the above Private IP host) that the below Public Port number
will be changed to when the packet enters your LAN (to the LAN Server/Client IP)
Protocol
Select the port number protocol type (TCP, UDP).

Example: Virtual Server
The diagram below demonstrates one of the ways you can use the Virtual Server function. Use the Virtual Server when
you want the web server located in your private LAN to be accessible to Internet users. The configuration below means
that any request coming form the Internet to access your web server will be translated to your LAN’s web server
(192.168.2.2).
Note:
For the virtual server to work properly Internet/remote users must know your global IP address. (For websites you
will need to have a fixed/static global/public IP address)
2.5.2 Special Applications
Some applications require multiple connections, such as Internet games, video conferencing, Internet telephony and
others. In this section you can configure the router to support multiple connections for these types of applications.
Parameters
Description
Name
The description of this setting.
Incoming Type
Select the Inbound port protocol type: “TCP”, “UDP” or both
Incoming Port Range
Enter the In-coming (Inbound) port or port range for this type of application (e.g.
2300-2400, 47624)
