HG232f 300Mbps Wireless Router
User Guide
5-14
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.
Step 3
In the navigation tree, choose

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
Basic
>

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
.
Page 45 / 68

HG232f 300Mbps Wireless Router
User Guide
5-18
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 3
Click
Port Mapping
.
Step 4
Click
New
.
Step 5
Select
Application
, and then select
Security
web server (HTTPS)
for
Application
.
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
