Section 3 - Conﬁguration

Application Level Gateway Conﬁguration

Here you can enable or disable ALG’s. Some protocols and applications require special handling of the IP payload to make them work with network

address translation (NAT). Each ALG provides special handling for a speciﬁc protocol or application. A number of ALGs for common applications

are enabled by default.

Allows multiple machines on the LAN to connect to their corporate network using PPTP protocol.

Allows multiple VPN clients to connect to their corporate network using IPSec. Some VPN clients support traversal of IPSec through

NAT. This ALG may interfere with the operation of such VPN clients. If you are having trouble connecting with your corporate

network, try turning this ALG oﬀ. Please check with the system administrator of your corporate network whether your VPN client

supports NAT traversal.

Allows applications that use Real Time Streaming Protocol to receive streaming media from the internet. QuickTime and Real Player

are some of the common applications using this protocol.

Allows devices and applications using VoIP (Voice over IP) to communicate across NAT. Some VoIP applications and devices have

the ability to discover NAT devices and work around them. This ALG may interfere with the operation of such devices. If you are

having trouble making VoIP calls, try turning this ALG oﬀ.

Enter the IP address of packets that will take this

route.

Enter the netmask of the route, please note

that the octets must match your destination IP

address.

Enter your next hop gateway to be taken if this

route is used.

The route metric is a value from 1 to 16 that

indicates the cost of using this route. A value 1 is

the lowest cost and 15 is the highest cost.

Select the interface that the IP packet must use to

transit out of the router when this route is used.

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) 3 is the default

setting. A DTIM is a countdown informing clients

of the next window for listening to broadcast and

multicast messages.

WMM is QoS for your wireless network. This will improve the quality of video and voice applications for your wireless clients.

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.

WISH is short for Wireless Intelligent Stream Handling, a technology developed to enhance your experience of using a wireless network by prioritizing

the traﬃc of diﬀerent applications.

Enable this option if you want to allow WISH to

prioritize your traﬃc.

Enable WISH:

Allows the router to recognize HTTP transfers

for many common audio and video streams and

prioritize them above other traﬃc. Such streams

are frequently used by digital media players.

HTTP:

Enables the router to recognize certain audio and

video streams generated by a Windows Media

Center PC and to prioritize these above other

traﬃc. Such streams are used by systems known

as Windows Media Extenders, such as the Xbox

360.

Windows Media

Center:

When enabled, this option causes the router to

automatically attempt to prioritize traﬃc streams

that it doesn’t otherwise recognize, based on

the behavior that the streams exhibit. This acts

to deprioritize streams that exhibit bulk transfer

characteristics, such as ﬁle transfers, while leaving

interactive traﬃc, such as gaming or VoIP, running

at a normal priority.

Automatic:

WISH Rules:

A WISH Rule identiﬁes a speciﬁc message ﬂow and assigns a priority to that ﬂow. For most applications, the priority classiﬁers ensure

the right priorities and speciﬁc WISH Rules are not required.

WISH supports overlaps between rules. If more than one rule matches for a speciﬁc message ﬂow, the rule with the highest priority

will be used.

Wi-Fi Protected Setup (WPS)

Enable the Wi-Fi Protected Setup feature.

Locking the wireless security settings prevents the settings from

being changed by the Wi-Fi Protected Setup feature of the router.

Devices can still be added to the network using Wi-Fi Protected

Setup. However, the settings of the network will not change once

this option is checked.

A PIN is a unique number that can be used to add the router to

an existing network or to create a new network. The default PIN

may be printed on the bottom of the router. For extra security,

a new PIN can be generated. You can restore the default PIN at

any time. Only the Administrator (“admin” account) can change

or reset the PIN.

Shows the current value of the router’s PIN.

Restore the default PIN of the router.

Create a random number that is a valid PIN. This becomes the

router’s PIN. You can then copy this PIN to the user interface of

the registrar.

This Wizard helps you add wireless devices to the wireless

network.

The wizard will either display the wireless network settings to guide you through manual conﬁguration, prompt you to enter the PIN for the device, or ask you

to press the conﬁguration button on the device. If the device supports Wi-Fi Protected Setup and has a conﬁguration button, you can add it to the network by

pressing the conﬁguration button on the device and then the on the router within 60 seconds. The status LED on the router will ﬂash three times if the device

has been successfully added to the network.

There are several ways to add a wireless device to your network. A “registrar” controls access to the wireless network. A registrar only allows devices onto the

wireless network if you have entered the PIN, or pressed a special Wi-Fi Protected Setup button on the device. The router acts as a registrar for the network,

although other devices may act as a registrar as well.

Wi-Fi Protected Setup (WPS) System is a simpliﬁed method for securing your wireless network during the “Initial setup” as well as the “Add New

Device” processes. The Wi-Fi Alliance (WFA) has certiﬁed it across diﬀerent products as well as manufactures. The process is just as easy, as depressing

a button for the Push-Button Method or correctly entering the 8-digit code for the Pin-Code Method. The time reduction in setup and ease of use

are quite beneﬁcial, while the highest wireless Security setting of WPA2 is automatically used.
