Enter the port that you want to open next to Private Port and

Public Port. The private and public ports are usually the same. The

public port is the port seen from the Internet side, and the private

port is the port being used by the application on the computer

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-657. If you need to run applications that require multiple connections, specify the port normally associated with an application in the “Trigger

Port” ﬁeld, select the protocol type as TCP or UDP, then enter the ﬁrewall (public) ports associated with the trigger port to open them for inbound

traﬃc.

The DIR-657 provides some predeﬁned applications in the table on the bottom of the web page. Select the application you want to use and enable it.

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 classiﬁed 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.

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.

This option is enabled by default. This will allow your

router to automatically determine the network priority of

running programs.

This option is enabled by default so that your router will

automatically determine which programs should have

network priority. For best performance, use the Automatic

Classiﬁcation option to automatically set the priority for

your applications.

This option should be enabled when you have a slow

Internet uplink. It helps to reduce the impact that large low

priority network packets can have on more urgent ones.

Section 3 - Conﬁguration

A QoS Engine Rule identiﬁes a speciﬁc message ﬂow and

assigns a priority to that ﬂow. For most applications, automatic

classiﬁcation will be adequate, and speciﬁc QoS Engine Rules

will not be required.

The QoS Engine supports overlaps between rules, where more

than one rule can match for a speciﬁc message ﬂow. If more

than one rule is found to match the rule with the highest

priority will be used.

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

The priority of the message ﬂow is entered here -- 1 receives

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

priority (least urgent).

The protocol used by the messages.

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

address falls 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 falls within the range set here.

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

number is within the range set here.
