Special Applications

The Special Application section is used to open single or multiple ports on your router when the

router senses data sent to the Internet on a ‘trigger’ port or port range. Special Applications rules

apply to all computers on your internal network.

Application Level Gateway (ALG) Conﬁgurations

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 adminstrator 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 FTP clients and servers to transfer data across NAT. Refer to the

Advanced -> Virtual Server page if you want to host an FTP server.

Allows Microsoft NetMeeting clients to communicate across NAT. Note that

if you want your buddies to call you, you should also set up a virtual server

for NetMeeting. Refer to the Advanced -> Virtual Server page for information

on how to set up a virtual server.

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.

Allows Windows Media Player, using MMS protocol, to receive streaming

media from the internet.

Allows multiple machines on the LAN to connect to their corporate network

using the L2TP protocol.

Allows all of the Windows Messenger functions to work properly through

the router.

Add/Edit Special Applications Rule

The Special Application section is used to open single or multiple ports on your router when the

router senses data sent to the Internet on a “trigger” port or port range. Special Applications rules

apply to all computers on your internal network.

Enter a name for the Special Application Rule, for example

Game App

,

which will help you identify the rule in the future. You can also select from

a list of common applications, and the remaining conﬁguration values will

be ﬁlled in accordingly.

Enter the outgoing port range used by your application.

Select the outbound protocol used by your application.

Enter the port range that you want to open up to Internet trafﬁc.

Select the protocol used by the Internet trafﬁc coming back into the router

through the opened port range.

Select a schedule for when this rule is in effect. If you do not see the schedule

you need in the list of schedules, go to the Tools -> Schedules screen and

create a new schedule.

Saves the new rule or modiﬁed existing rule to the Rules list. When you are

done editing the settings, you must click the Save Settings button at the top

of the page to make the changes effective and permanent.

Entries on this list can be enabled/disabled by toggling the Enable checkbox. Entries can be modiﬁed

by clicking on the paper and pencil icon. To delete an entry, click on the trash can icon. After you’ve

completed all modiﬁcations or deletions, you must click the

button at the top of the

page to save your changes. The router must reboot before new settings will take effect. You will be

prompted to

Reboot the Device

or

Continue

. If you need to make additional settings changes, click

Gaming

The Gaming section is used to open multiple ports or a range of ports in your router and redirect

data through those ports to a single PC on your network. This feature allows you to enter ports in

various formats:

Add/Edit Game Rule

Give the Gaming Rule a name that is meaningful to you, such as Game

Server. You can also select from a list of pre-deﬁned rules for many popular

games. If you have any trouble with pre-deﬁned rules, verify whether the

port values have changed since the list was created. You also must ﬁll in

the IP address ﬁeld.

Enter the local network IP address of the system hosting the game server,

such as 192.168.0.50.

Enter the TCP ports to open, such as 6159-6180, 99

Enter the UDP ports to open, such as 6159-6180, 99

Select a schedule for when this rule is in effect. If you do not see the schedule

you need in the list of schedules, go to the Tools -> Schedules screen and

create a new schedule.

Saves the new rule or modiﬁed existing rule to the Rules list. When you are

done editing the settings, you must click the Save Settings button at the top

of the page to make the changes effective and permanent.

GameFuel

™

The GameFuel

™

option helps improve your network gaming performance by prioritizing applications. By

default the GameFuel settings are disabled and application priority is not classiﬁed automatically.

GameFuel

™

Setup

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 GameFuel option is enabled.

This option will allow your router to automatically determine which programs

should have network priority.

This option should be enabled when you have a slot Internet uplink. It helps

to reduce the impact that large low priority network packets can have on

more urgent ones.

This option is enabled by default when the GameFuel option is enabled. This

option will allow your router to automatically determine the uplink speed of

your Internet connection.

This displays the detected uplink speed.

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 WAN settings, setting this option to

xDSL

or Other Frame Relay Network

ensures that the router will recognize

that it needs to shape trafﬁc slightly differently 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

, the automatically detected

connection type is displayed here.

Rule

Automatic classiﬁcation should be adequate for most applications. GameFuel rules identify a speciﬁc

message ﬂow and assign priority to that ﬂow.

Create a name for the rule that is meaningful to you.

The priority of the message ﬂow is entered here. O receives the highest

priority (most urgent) and 255 receives the lowest priority.

The protocol used by the messages.

The rule applies to a ﬂow of messages whose LAN-side IP address is within

the range set here.

The rule applies to a ﬂow of messages whose LAN-side port number is

within the range set here.

The rule applies to a ﬂow of messages whose WAN-side IP address is

within the range set here.

The rule applies to a ﬂow of messages whose WAN-side port number is
