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-826L. 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-826L 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
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. 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 speedtest.net.
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.

disabled and application priority is not classified automatically.
