Each computer can be configured with only one bandwidth control rule.

A bandwidth control rule distinguishes different computer s based on the IP addresses of

the computer s. It is recommended that you configure your computer to obtain an IP

address from the router automatically. After the IP address of your computer is obtained,

you can configure the bandwidth control rule based on this IP address. The router can

record the mapping between the MAC address and IP address of a computer and thus

ensure that the same IP address can be assigned to the same computer every time.

Configuration Example

For example, you use a computer for video communications with your friend over the

Internet and the name of your computer is

NXF-HP

. To ensure a fast data transmission

rate and smooth video quality, you can use the traffic control function of the router and

configure a bandwidth control rule for the computer named

NXF-HP

. The parameters of

the rule are as follows:



Mode: Assure Minimum Bandwidth



Download: 500 kbit/s



Upload: 500 kbit/s

The configuration procedure is as follows:

Step 1

Connect the computer named

NXF-HP

to the router through a wired network or a

WLAN.

Ensure that the computer can access the Internet.

Step 2

Log in to the Web-based configuration utility.

5.7 Preventing Attacks on the Internet

Function Overview

The Internet is an open network that is connected to computers all over the world,

leaving computers on the Internet vulnerable to attacks at anytime. To help protect your

computer from these attacks, the router provides powerful firewall functions. By using a

firewall, a protective shelter is established between your home network and the Internet.

Configuration Example

If you have stringent requirements for network security, you can set the firewall level of

the router to

High

as follows:

5.8 Removing the Restriction Caused by the Binding of

the Internet Access Account to the MAC Address

Function Overview

Certain network service providers bind your Internet access account to the MAC address

of your computer's network adapter; only the computer with that MAC address can

connect to the Internet. When this is the case, the MAC address of the router cannot be

found in the network devices of a network service provider. As a result, the router cannot

connect to the Internet and the computers connected to the router also cannot access the

Internet.

You can use the MAC address cloning function of the router to remove this restriction.

Through this function, the MAC address used during communication between the router

and the network devices of a network service provider becomes the MAC address that is

bound to the Internet access account. The router can then be connected to the Internet

properly.

Configuration Example

If you use computer 1 to access the Internet, your network service provider binds your

Internet access account to the MAC address of computer 1's network adapter. Now, if

multiple computers are added to your home and you need to use the router to access the

Internet, you can use the MAC address cloning function of the router to change the MAC

address of the router to that of computer 1's network adapter.

The configuration procedure is as follows:

Step 1

Log in to the web-based configuration utility on computer 1.

Step 2

In the navigation tree, choose

5.9 Allowing Internet Users to Access an Internal

Resource Server

Function Overview

Without special settings, Internet users cannot access the web or FTP servers on a LAN.

By using the network address translation (NAT) function of the router, specified Internet

users are allowed to access the web and FTP servers on a LAN.

Furthermore, IP addresses used by most users to access the Internet are dynamically

assigned by network service providers, so many cannot use fixed IP addresses to access

the resources provided on servers. The router's Dynamic Domain Name Service (DDNS)

function allows Internet users to use fixed domain names to access the resources

provided on servers.

After the DDNS function is enabled, the router automatically submits the new IP address

obtained to the server of a DDNS provider. On the DDNS server, the IP address that

corresponds to the domain name is updated to the latest IP address. When a computer on

the Internet accesses the domain name, the DDNS server provides the latest IP address to

that computer.

Configuration Example

If you deploy a web server on a LAN and want Internet users to be able to access the web

site on the web server through a fixed domain name, the IP addresses of relevant devices

should be as follows:



The IP address of the router LAN interface is

192.168.3.1

.



The IP address of the web server is

192.168.3.166

.

You can use the port relay function of the NAT and DDNS function to implement the

preceding requirements.

Before the configuration, you need to complete the following actions:



Apply for the DDNS from a DDNS provider to obtain relevant parameters.



Apply for a domain name for the web site from the institution that manages web site

domain names.

After the preceding actions, set the parameters of the router as follows:



Configure a port mapping rule, and then map the IP address of the web server

(

192.168.3.166:80

) to the

80

port of the WAN interface.



Configure the DDNS. Ensure that the router can submit IP addresses to the DDNS

server automatically.

The configuration procedure is as follows:

Step 1

Log in to the web-based configuration utility.

Step 2

In the navigation tree, choose

Advanced

>

NAT

.

The NAT page is then displayed.

Step 4

.

The port mapping function of the router provides parameter setting templates of multiple

applications. After a template is selected, the router sets relevant parameters automatically. You

can change the parameter settings as required. You can also set all the parameters manually based

on the requirements of other applications.

Step 6

Set the following parameters as planned.



External start port: 80



External end port: 80



Internal host: 192.168.3.166



Internal port: 80
