Some applications require multiple connections, such as Internet gaming, video conferencing, and Internet telephony. These

applications may have diﬃculty working through NAT (Network Address Translation). Special Application Rules make some

of these applications work with the DIR-866L. If you must run applications that require multiple connections, specify the

port normally associated with an application in the

Trigger Port

TCP

or

UDP

, then enter the

Firewall

(public) ports associated with the trigger port to open them for inbound traﬃc.

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.
