31


interference in order to enhance wireless performance.

Channel Width It specifies the frequency width of the channel of the router. The default is recommended.

SSID It specifies the name of the wireless network of the router.

Encryption Mode

Encryption Type involves how your communication is secured and affects your network security. The router supports None, WEP and WAP Personal.

None: It indicates that the wireless network is not encrypted.

WEP: Wired Equivalent Privacy (WEP) uses a static key to encrypt all data exchanges, and ensures that a wireless LAN has the same level of security as a wired LAN. Under this mode, you need to set the Authentication Mode and the WEP Default Key.

WAP Personal: It indicates another encryption mode for data exchange. Under this mode, you need to set WAP Mode, Cipher Type and Pre‐shared key.

Authentication Method

The available authentication modes include Open System and Shared Key.

Open System: It specifies that authentication is not required if the Encryption Type is WEP. In this case, a wireless client can connect to the router without being authenticated, and the data exchanged between them is encrypted in WEP security mode.

Shared Key: It specifies that authentication is not required if the Encryption Type is WEP. In this case, a wireless client can connect to the router without being authenticated, and the data exchanged between them is encrypted in WEP security mode.

WEP Encryption Length

It specifies the length of the key that you set for the wireless network.

WEP Default Key

It specifies the default WEP key for the Open System and Shared Key encryption types.

For example, if the default key is set to WEP key 2, a wireless client can connect to the router only with WEP key 2.

The router provides two WEP key types: ASCII and Hex.

ASCII: It allows 5 or 13 ASCII characters in a WEP key.

Hex: It allows 10 or 26 hexadecimal characters in a WEP key.

WPA Mode

WPA: It indicates that the router works in the WPA security mode.

WPA2: It indicates that the router works in the WPA2 security mode.

Auto (WPA or WPA2): It indicates that the router works in the Auto(WPA or WPA2) security mode, and wireless clients adopting the WPA or WPA2 security mode can connect to the router.

Cipher Type AES: It is short for Advanced Encryption Standard. If this encryption algorithm is

32


used, the router can reach a maximum wireless transmission rate of 300 Mbps.

TKIP: It is short for Temporal Key Integrity Protocol. If this encryption algorithm is used, the router can reach a maximum wireless transmission rate of 54 Mbps.

TKIP and AES: It indicates that both TKIP and AES encryption algorithms are supported. Wireless clients can connect to the router based on TKIP or AES.

Pre‐shared Key It specifies the connection password for wireless devices.

Application Scenario

A 4G680 is used to set up a LAN and a web server on the LAN must be accessible to internet users.

This requirement can be addressed using the virtual server function. The following figure shows

the application scenario.

Network requirement

The WAN port of the router is assigned a public IP address.

Computer 1 is assigned a static IP address. The default gateway IP address is the 192.168.0.150.

All the firewall and antivirus software that may deny internet users' access to the LAN server is disabled when virtual server function is used.

Configuration

Procedures for configuring the virtual server function:


Step 2 Choose Security > NAT.

IP address of the web server:

192.168.0.150

WAN IP address of the router:

102.33.66.88

44

Step 3 Click Add.

Step 4 Enter the IP address of the virtual server, which is 192.168.0.150 in this example.

Step 5 Define a Private Port and Global Port, which are both 9999 in this example.

Step 6 Select a Protocol, and click Apply.

If you want to modify the present rule, click the corresponding parameter and modify it. Click OK and Apply to enable it.

‐‐‐End

After the settings, users from the internet can access the virtual server by visit the address in a

web browser “Intranet service layer protocol name://the present WAN IP address of the

router:global port”.

For example, when the WAN IP address of the router is 102.33.66.88, set the private port to 9999

and Global port to 9999, you can visit “http:// 102.33.66.88:9999” to access the visual server.

9.3 DMZ

9.3.1 Overview

You can set a certain computer as a DMZ Host to free the computer from any restriction in the

process of accessing the internet. Therefore, the DMZ Host can obtain better internet experience.

For example, a video meeting and online games can be smoother on a DMZ host.

When a computer is set as a DMZ host, it is completely exposed to the internet, which means that the computer will not be protected by the firewall of the router.

A DMZ host can be easily used by hackers to attack the local network. Do not set DMZ host randomly.

Security software, anti‐virus software and system firewall may affect the DMZ function. Please disable these safety measures during the use of DMZ function.


DMZ Host It specifies the IP address of the device that is set as a DMZ host.

9.3.2 Access the LAN with an IP address from the internet

Network requirement

Assume that you have a FTP server under the LAN of the router, and you want to share the

resources on the server to allow family members to access those resources from the internet.

Solution

You can meet the requirement with the DMZ host function.

Assume that:

The IP address of the FTP server: 192.168.0.101.

The MAC address of the host of the FTP server: D4:61:DA:1B:CD:89.

The service port of the FTP server: 21.

46

Please ensure that router obtains an IP address from the public network. This function may not work on a host with an IP address of a private network. Common IPv4 addresses are classified into class A, class B and class C. Private IP addresses of class A range from 10.0.0.0 to 10.255.255.255; Private IP addresses of class B range from 172.16.0.0‐172.31.255.255; Private IP addresses of class C range from 192.168.0.0‐192.168.255.255.

Procedures for setting a DMZ host:


Step 2 Choose Security > DMZ.

Step 3 Enter 192.168.0.101 in DMZ Host.

Step 4 Click Apply.

‐‐‐End

Follow the steps above for setting a DMZ host, you can access the intranet server by visiting

“Intranet service layer protocol name://the present WAN IP address of the router”, which is

“ftp://102.33.66.88” in this example. If the intranet service port is not the default port, you can

access the intranet server by visiting “Internal service layer protocol name://the present WAN IP

address of the router:internal service port”.

When the default intranet service port is 80, please change it to an uncommon port (1024‐65535) manually, such as 9999.

If internet users still cannot access the server after the configuration, please try to disable the system firewall, anti‐virus software on the DMZ host and try again.
