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-868L. 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-868L provides some predefined applications in the table on the bottom of the web page. Select the application you
want to use and enable it.

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 automatically classified. The QoS section contains a queuing mechanism, traffic shaping and classification. It supports
two kinds of queuing mechanisms. Strict Priority Queue (SPQ) and Weighted Fair Queue (WFQ). SPQ will process traffic based on traffic priority.
Queue1 has the highest priority and Queue4 has the lowest priority. WFQ will process traffic based on the queue weight. Users can configure each
queue’s weight. The sum of all the queue’s weight must be 100. When surfing the Internet, the system will do traffic shaping based on the uplink
and downlink speed. The classification rules can be used to classify traffic to different queues, then SPQ or WFQ will do QoS based on the queue’s
priority or weight.

Section 3 - Configuration
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 WAN-side IP address falls within the range set here.
Select a service or port you want to assign to this rule.
