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

4.5 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.
