trafﬁc matching the ﬁrewall rule.

Use the drop-down menus to select the

Source

and

Destination

interfaces for the Firewall Rule

Use the

IP Address

ﬁelds next to each

Interface

drop-down

menu to specify the IP address ranges for the Source/Destination

interfaces.

The ﬁrst host in the IP address range should be entered in the top

ﬁeld and the last host in the IP address range should be entered in

the ﬁeld beneath for both the Source/Destination intefaces.

Use the drop-down menu to select the protocol that will be used for

the ﬁrewall rule (TCP, UDP, ICMP, or ALL).

Enter the range of ports that the ﬁrewall rule will apply to.

The ﬁrst port in the port range should be entered in the top ﬁeld

and the last host in the port range should be entered in the ﬁeld

beneath.

Section 3 - Conﬁguration

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 2432.

If inconsistent data ﬂow is a problem, only a minor

modiﬁcation should be made.

The fragmentation threshold, which is speciﬁed 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 deﬁnes 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. Note: High network trafﬁc areas should use the

Short Preamble

type.

Use the drop-down menu to select the wireless modes you want to enable on the router. The available options are

802.11n

only

,

802.11 Mixed(g/b)

, and

802.11 Mixed(n/g/b)

.

This setting can be used to adjust the bandwidth of the wireless signal. The default setting is

20/40 MHz (Auto)

.

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.

ed

Multicast Streams

To use the Universal Plug and Play (UPnP

™

) feature

check the

Enable UPNP

box. UPNP provides

compatibility with networking equipment, software

and peripherals.

Unchecking the box will not allow the DIR-412 to

respond to pings. Blocking the Ping may provide some

extra security from hackers. Check the box to allow

the Internet port to be “pinged”.

You may set the port speed of the Internet port to

10Mbps, 100Mbps, or auto. Some older cable or

DSL modems may require you to set the port speed

to 10Mbps.

Check the

Enable Multicast Streams

box to allow

multicast trafﬁc to pass through the router from the

Internet.

Check the

Wireless Enhance Mode

box to enable

the router to forward all multicast streams from the

Internet to the wireless station using a unicast stream.

This feature helps improve the quality of multimedia

applications for wireless users.

Remote management allows the DIR-412 to be

conﬁgured from the Internet by a web browser. A

username and password is still required to access the

Web-Management interface. In general, only a member

of your network can browse the built-in web pages

to perform Administrator tasks. This feature enables

you to perform Administrator tasks from the remote

(Internet) host.

The port number used to access the DIR-412.

Example: http://x.x.x.x:8080 whereas x.x.x.x is the

Internet

IP address of the DIR-412 and 8080 is the
