computer at the same time, which differs from Port Range
Forwarding, which can only forward a maximum of 10
ranges of ports.

Enabled. Otherwise, keep the default, Disabled.
High priority/Medium priority/Low priority
application, select High priority (traffic on this queue
shares 60% of total bandwidth), Medium priority (traffic on
this queue shares 18% of total bandwidth), or Low priority
(traffic on this queue shares 1% of total bandwidth).
