Application Rules

Some applications require multiple connections, such as Internet gaming, video conferencing, Internet telephony and

others. These applications have difficulties working through NAT (Network Address Translation). Special Applications

makes some of these applications work with the DIR-600.

Check the box to enable the rule.

Enter a name for the rule.

This is the port used to trigger the application. It

can be either a single port or a range of ports.

This is the port number on the WAN side that

will be used to access the application. You may

define a single port or a range of ports. You

can use a comma to add multiple ports or port

ranges.

Select TCP, UDP, or Any.

QoS Engine

The QoS Engine option helps improve your network gaming performance by prioritizing applications. By default the

QoS Engine settings are disabled and application priority is not classi±ed automatically.

This option is disabled by default. Enable this

option for better performance and experience with

online games and other interactive applications,

such as VoIP.

This option is enabled by default when the QoS

Engine option is enabled. This option will allow

your router to automatically determine the uplink

speed of your Internet connection.

The speed at which data can be transferred from

the router to your ISP. This is determined by your

ISP. ISP’s often speed as a download/upload

pair. For example, 1.5Mbits/284Kbits. Using this

example, you would enter 284. Alternatively you

can test your uplink speed with a service such

as www.dslreports.com.

By default, the router automatically determines whether the underlying connection is an xDSL/Frame-relay

network or some other connection type (such as cable modem or Ethernet), and it displays the result as

Detected xDSL or Frame Relay Network. If you have an unusual network connection in which you are actually

connected via xDSL but for which you configure either “Static” or “DHCP” in the Internet settings, setting

this option to xDSL or Other Frame Relay Network ensures that the router will recognize that it needs to

shape tra³c slightly di²erently in order to give the best performance. Choosing xDSL or Other Frame Relay

Network causes the measured uplink speed to be reported slightly lower than before on such connections,

but gives much better results.

When Connection Type is set to automatic, the automatically detected connection type is displayed here.

Select Turn MAC Filtering OFF, Turn MAC Filtering

ON and ALLOW computers listed to access the

network, or Turn MAC Filtering ON and DENY

computers listed to access the network.

Enter the MAC address you would like to ±lter.

To find the MAC address on a computer, please

Firewall฀&฀DMZ

This section will allow you to set up a DMZ host and to set up ±rewall rules.

If you have a client PC that cannot run Internet applications properly from behind the DIR-600, then you can set the

client up for unrestricted Internet access. It allows a computer to be exposed to the Internet. This feature is useful for

gaming purposes. Enter the IP address of the internal computer that will be the DMZ host. Adding a client to the DMZ

(Demilitarized Zone) may expose your local network to a variety of security risks, so only use this option as a last

resort.

Check this to enable SPI.

Check this box to enable DMZ.

Enter the IP address of the computer you would

like to open all ports to.

Choose a name for the ±rewall rule.

Select to Allow or Deny transport of the data packets

according to the criteria de±ned in the rule.

The Source/Destination is the TCP/UDP port on

either the LAN or WAN side.

Set the transmit power of the antennas.

Beacons are packets sent by an Access Point to synchronize a wireless

network. Specify a value. 100 is the default setting and is recommended.

This value should remain at its default setting of 2346. If inconsistent data

´ow is a problem, only a minor modi±cation should be made.

The fragmentation threshold, which is speci±ed in bytes, determines whether

packets will be fragmented. Packets exceeding the 2346 byte setting will be

fragmented before transmission. 2346 is the default setting.

(Delivery Traffic Indication Message) 1 is the default setting. A DTIM is a

countdown informing clients of the next window for listening to broadcast

and multicast messages.

Select Short or Long Preamble. The Preamble de±nes the length of the CRC

block (Cyclic Redundancy Check is a common technique for detecting data

transmission errors) for communication between the wireless router and the

roaming wireless network adapters. Auto is the default setting. Note: High network tra³c areas should use the shorter preamble type.

CTS (Clear To Send) is a function used to minimize collisions among wireless devices on a wireless local area network

(LAN). CTS will make sure the wireless network is clear before a wireless client attempts to send wireless data. Enabling

CTS will add overhead and may lower wireless through put.

None:

CTS is typically used in a pure 802.11g environment. If

CTS is set to “None” in a mixed mode environment populated by 802.11b clients, wireless collisions may occur frequently.

Always:

CTS will always be used to make sure the wireless LAN is clear before sending data.

Auto:

CTS will monitor the wireless network

and automatically decide whether to implement CTS based on the amount of tra³c and collisions that occurs on the wireless network.

802.11n Only - Select only if all of your wireless clients are 802.11n.

Mixed 802.11n, 802.11b, and 802.11g - Select if you are using a mix of 802.11n, 11g, and 11b wireless clients.

Select if you are using both 802.11n and non-802.11n wireless devices.

Select if you are not using any 802.11n wireless clients. This is the default setting.

Check this box to reduce the guard interval time therefore increasing the data capacity.

However, it’s less reliable and may create higher

data loss.
