User manual

4.4.5 Advanced

This tab is used to set up the Router’s advanced wireless functions. These settings should only be adjusted

by an expert administrator as incorrect settings can reduce wireless performance.

z

Beacon Interval

: This value indicates the frequency interval of the beacon. A beacon is a packet

broadcast by the wireless router to keep the network synchronized. A beacon includes the wireless LAN

service area, a time stamp, Delivery Traffic Indicator Maps, and the Traffic Indicator Message (TIM).

The default value is 100.

z

RTS Threshold

: This value should remain at its default setting of 2,347. Should you encounter

inconsistent data flow, only minor modifications are recommended.

z

DTIM Interval

: This value indicates how often the Access Point sends out a Delivery Traffic Indication

Message (DTIM). Lower settings result in more efficient networking, while preventing your PC from

dropping into power saving sleep mode. Higher settings allow your PC to enter sleep mode, thus saving

power, but interferes with wireless transmissions.

z

Transmit Rate

: The “Transmit Rate “is the data packets limitation this wireless router can transmit, The

wireless router will use the highest possible selected transmission rate to transmit the data packets. The

default value is Auto.

z

Preamble Type

: It defines the length of CRC block in the frames during the wireless Communication.

"Short Preamble" is suitable for heavy traffic wireless network. "Long Preamble" provides much

communication reliability

4.4.6 Association Table

4.5 Routing

If the Router is connected to more than one network, it may be necessary to set up a static route between

them. A static route is a pre-determined pathway that network information must travel to reach a specific host

or network.

z

Type / Target / Mask / Gateway

: Fill in these fields required by this Static Routing function.

z

Add

: Fill in the all of the setting to be added and click "Add", then this Special Application setting will be

added into the "Current Routing Table" below.

z

Current Routing Table

: This display shows the valid routing paths in Broadband Router. User can view

the information about current routing paths

If you want to remove some route entries from the “Current Routing Table ", select the Route entry you

want to remove in the table and then click "Delete ".

4.6 NAT

Network Address Translation (NAT) allows multiple users at your local site to access the Internet through a

single Public IP Address. 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.

4.6.1 DMZ Host Setup

If you have a local client PC that cannot run an Internet application (e.g. Games) properly from behind the

NAT firewall, you can place this client to unrestricted two-way Internet access by defining a DMZ Host. The

DMZ function allows you to re-direct all packets going to your WAN port IP address to a particular IP address

in your LAN. The difference between the virtual server and the DMZ function is that the virtual server

re-directs a particular service/Internet application (e.g. FTP, websites) to a particular LAN client/server,

whereas DMZ re-directs all packets (regardless of services) going to your WAN IP address to a particular

LAN client/server.

z

DMZ :

Enable/disable DMZ

z

DMZ Host:

Input the IP address of a particular host in your LAN that will receive all the packets

originally going to the WAN port/Public IP address above, you need to give your LAN PC clients a

fixed/static IP address for DMZ to work properly.

Click “Apply” at the bottom of the screen to save the DMZ configurations.

If there is a conflict between the Virtual Server and the DMZ setting, then Virtual Server function will

have priority over the DMZ function.

4.6.2 FTP Private Port

FTP private port enables user to setup FTP server which is not using the standard port 21.

z

Check port number and enter the number and then press the "Apply" button to setup Private FTP port.

The default Value is 1025.

4.6.3 Virtual Server Setup

Use the Virtual Server function when you want different servers/clients in your LAN to handle different

service/Internet application type (e.g. Email, FTP, Web server etc.). Computers use port numbers to

recognize a particular service/Internet application type. The Virtual Server allows you to re-direct a particular

service port number (from the Internet/WAN Port) to a specified LAN private IP address and its service port

number.

z

Rule Name

: Define a name for this rule. It's just a string.

z

Internal Server IP

: Enter the host IP address to which the packet will be forwarded. The virtual server

can be set easily by setting the internal server IP address only. You need to give your LAN PC clients a

fixed/static IP address for Virtual Server to work properly.

z

Protocol

: Chose TCP/UDP type for the packet you want to forward.

If the rule existed in predefined

virtual server rule, you can choose the rule.

z

External Port

: Enter the port number (The value's range is 1 to 65535) from which the packet will be on

WAN.

z

Internal Port

: Enter the port number to which the packet will be forwarded on LAN

z

Press "Add" button after enter the all fields to add the rule.

z

Check to select the rule and press "Delete" to delete the rule.
