Edit QoS Rule:

You can assign packet classification criteria by its local IP range, remote IP range, traffic type,

protocol, local port range and remote port range parameters. The parameters that you leave as

blank will be ignored. The priority of this rule will be applied to packets that match classification

criteria of this rule. You can limit bandwidth consumed by packets that match this rule or

guarantee bandwidth required by packets that match this rule.

Parameters

Description

Rule Name

The name of this rule.

Bandwidth

You can assign the download or upload

bandwidth by the unit of Kbps (1024 bit per

second). You can limit the maximum bandwidth

consumed by this rule by selecting

“

Maximum

”

.

You also can reserve enough bandwidth for this

rule by selecting

“

Guarantee

”

.

Local IP Address

Enter the local IP address range of the packets

that this rule will apply to. If you assign

192.168.2.3

–

192.168.2.5, it means 3 IP

addresses: 192.168.2.3, 192.168.2.4 and

192.168.2.5

Local Port Range

Enter the local port range of the packets that this

rule will apply to. You can assign a single port

number here or assign a range of port numbers

by assigning the first port number and the last

port number of the range. The two numbers are

separated by a dash

“

-

“

, for example

“

101-150

”

means from port number 100 to port number

150

–

the range of 50 port numbers.

58

Remote IP Address

Enter the remote IP address range of the

packets that this rule will apply to. If you assign

192.168.2.3

–

192.168.2.5, it means 3 IP

addresses: 192.168.2.3, 192.168.2.4 and

192.168.2.5

Remote Port Range

Enter the remote port range of the packets that

this rule will apply to. You can assign a single

port number here or assign a range of port

numbers by assigning the first port number and

the last port number of the range. The two

numbers are separated by a dash

“

-

“

, for

example

“

101-150

”

means from port number 100

to port number 150

–

the range of 50 port

numbers.

Traffic Type

Select the traffic type of the packets that this rule

will apply to. We list some popular applications

here to ease the configuration. You also can get

the same result by using other parameters, for

example source or destination port number, if

you are familiar with the application protocol.

Protocol

Select the protocol type of the packets that this

rule will apply to.

Apply

Apply and exit the form.

Reset

2.6 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

2.6.1 Port Forwarding

You can have different services (e.g. email, FTP, Web

etc.) going to different service servers/clients in your

LAN. The Port Forwarding allows you to re-direct a

particular range of service port numbers (from the

Internet/WAN Ports) to a particular LAN IP address.

2.6.2 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.

2.6.3 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.

60

2.6.4 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.

2.6.5 ALG Setting

You can select special applications that need

“

Application Layer Gateway

”

to support here.

2.6.6 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.
