This is the port used to trigger the application. It can be either

a single port or a range of ports.

Select the protocol of the trigger port (TCP, UDP, or Both).

This is the port number on the Internet 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 the protocol of the firewall port (TCP, UDP, or Both).

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-857. 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-857 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 enabled.

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.
