Application Rules
Some applications require multiple connections, such as Internet gaming, video conferencing, Internet telephony and others.
These applications have difficulty working through NAT (Network Address Translation). Special Application Rules make some
of these applications work with the DIR-818LW. 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.
