5 Configuring Frequently Used Functions
5.1 Configuring Multiple PCs to Access the Internet
Simultaneously
Function Overview
The router provides four Ethernet interfaces and the WLAN function. Thus, you can
connect multiple PCs to the router wirelessly or through the Ethernet interfaces. Then the
PCs can access the Internet simultaneously through the routing function of the router.
Configuration Example
For example, you have a desktop computer that is used for accessing the Internet, a new
desktop computer, and a new laptop with a wireless network adapter installed. You can
configure the desktop computers and the laptop to access the Internet simultaneously. In
this example, the laptop is configured to access the Internet wirelessly.
Most configurations of the router are completed before delivery. You only need to
connect the desktop computers and the laptop to the router and set certain Internet access
parameters of the router as follows:
Step 1
Connect the two desktop computers to the router by using network cables.
For details, see chapter 2 "Hardware Installation."
Step 2
Connect the laptop to the router wirelessly by configuring the laptop.
For details, see chapter 4 "Configuration of WLAN Parameters."
Step 3
Set the Internet access parameters of the router to connect the router to the Internet.
Step 4
Configure network connections on the desktop computers and the laptop so that these
PCs can obtain IP addresses automatically.
For details, see chapter 3 "Configuration of Internet Access Parameters."
----End
If the desktop computers and the laptop cannot access the Internet after the preceding
configuration, the network service provider might have bound your Internet access account to
the Media Access Control (MAC) address of the network adapter of your old desktop
computer. To remove the restriction, see section 5.8 "Removing the Restriction Caused by the
Binding of the Internet Access Account to the MAC Address."

5.3 Improving the Security of a WLAN
The signals of a WLAN are transmitted in the air. Therefore, unauthorized persons can
receive the wireless signals easily. If the wireless signals are not encrypted, unauthorized
persons may use your WLAN or obtain the data transmitted on the WLAN. To ensure the
security of the data transmitted on the WLAN, the router provides multiple
security-related settings for the WLAN function. You can change these settings as
required to protect your WLAN from unauthorized access.
5.3.1 Hiding the Name of a WLAN
Function Overview
When accessing a WLAN, the user of a wireless client needs to enter the correct name of
the WLAN, that is, the service set identifier (SSID) of the WLAN. Generally, the
wireless signals transmitted from a wireless router carries the SSID. The wireless adapter
of a PC can find and display the SSID for selection and confirmation. Thus, manual
operations for selecting and configuring the WLAN can be simplified. The SSID,
however, is not encrypted. Therefore, anyone can find the WLAN, and then view the
SSID, and the security of the WLAN is reduced.
The router provides the function of hiding the SSID. After this function is enabled, the
wireless signals transmitted from the router do not carry the SSID. Thus, it is not possible
for unauthorized people to obtain the SSID from the wireless signals. In addition, the
user of a PC needs to enter the correct SSID manually to add the PC to the WLAN. Thus,
the security of the WLAN is increased.
The router also provides the multi-SSID function. You can configure multiple SSIDs,
and then enable one or multiple of them.
Through the multi-SSID function, multiple virtual access points of a WLAN can be
established. For a wireless client, each virtual access point can be used as a physical access

5.3.2 Changing the Name of a WLAN
Function Overview
If the router has hidden the SSID of a WLAN, you need to enter the SSID of the WLAN
manually when you use a PC to access the WLAN. If you enter a wrong SSID, the PC
cannot connect to the WLAN. Therefore, the security of the WLAN can be improved if
the SSID is difficult to be predicted.
An SSID consists of 1–32 American Standard Code for Information Interchange (ASCII)
characters. When the router is delivered, the SSID is preset. You can find this preset
SSID on the label on the real panel of the router. In addition, the router supports the
change of the SSID. You can change the SSID as required.
Configuration Example
If your current SSID index is SSID1 and if you have used this SSID for a certain period,

5.3.3 Using Secure Encryption
Function Overview
To ensure the security of a WLAN, an important solution is to select an optimum security
mode for the WLAN. After this security mode is used, a wireless client should provide
the corresponding password when connecting to the WLAN and data is being
transmitted after secure encryption. Thus, only authorized persons can use the WLAN
and the data transmitted on the WLAN is protected against unauthorized access.
The router supports WEP encryption and multiple security modes, such as WPA-PSK
and WPA2-PSK, thus meeting security requirements in diversified network
environments.
It is recommended that you set the security mode to WPA-PSK/WPA2-PSK and the
encryption mode to AES. Thus, the WLAN works efficiently and the security of the
WLAN is ensured. In addition, if a wireless adapter does not support a certain security
mode, it cannot be connected to the WLAN in this security mode. If you use the
recommended security and encryption modes, this problem can be avoided.

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 the network adapter of your PC. Thus, only the PC with that MAC address can be
connected to the Internet. In this case, the MAC address of the router cannot be found in
the network devices of a network service provider. Therefore, the router cannot be
connected to the Internet and the PCs connected to the router cannot access the Internet
also.
You can use the MAC address cloning function of the router to remove the restriction
caused by the binding of the Internet access account and the MAC address. Through this
function, the MAC address used during the communications between the router and the
network devices of a network service provider is the MAC address that is bound to the
Internet access account. Thus, the router can be connected to the Internet properly.

5.10 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, Internet users are
allowed to access the Web and FTP servers on the LAN.
In addition, the IP addresses used by most users for accessing the Internet are
dynamically assigned by network service providers. Thus, Internet users cannot use
fixed IP addresses to access the resources provided on servers. Through the Dynamic
Domain Name Service (DDNS) function of the router, Internet users can 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 each time 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
PC on the Internet accesses the domain name, the DDNS server provides the latest IP
address to the PC.
Configuration Example
For example, you deploy a Web server on a LAN. You want Internet users to be able to
access the Web site on the Web server through a fixed domain name. The IP addresses of
the relevant devices are as follows:
The IP address of the LAN interface of the router 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 the DDNS function to implement the
preceding requirement.
Before configuration, you need to complete the following preparations:
Apply for the DDNS to a DDNS provider and obtain the relevant parameters.
Apply for a domain name for the Web site to the institution for managing the domain
names of Web sites.
After the preceding preparations, plan 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.

5 Configuring Frequently Used Functions
WS325 300Mbps Wireless Router
User Guide
When configuring the WDS function, you should comply with the following principles:
Both wireless routers should support the WDS function.
The WDS function should be enabled on both wireless routers.
On each router, add the wireless MAC address of the peer router to the WDS MAC
list. No WDS MAC list is required to be configured on the router in lazy mode but a
WDS MAC list should be configured on the peer router.
The settings of the following parameters on both wireless routers should be the same:
−
Wireless channel
−
Encryption mode
−
Encryption password
The security modes set on the two wireless routers can be different but the encryption
modes should be the same.
The SSIDs of the two WLANs can be different but it is recommended that the two WLANs
use the same SSID. Thus, wireless terminals can use one SSID to connect to the WLAN
that is expanded.
If the repeater mode is used for expanding the coverage of a WLAN, note that:
−
The IP addresses of the LAN interfaces of the two routers should be in the same
network segment. In addition, the IP addresses should be different.
−
Enable the DHCP server function only on the wireless router that is used to
connect to uplink devices. Disable the DHCP function and enable the DHCP
relay function on other wireless routers.
Configuration Example
For example, you have router A in your spacious house. The signals of router A cannot
cover the area that is far from the router. In this case, you can add another router, that is,
router B. By configuring the WDS function on the two routers, you can expand the
coverage of a WLAN.
