DMZ
screen allows one local user to be exposed to the Internet for use of a special-purpose service such as
Internet gaming and videoconferencing through DMZ Hosting. DMZ hosting forwards all the ports for one
computer at the same time, which differs from Port Range Forwarding, which can only forward a maximum of 10
ranges of ports.

PVC QoS Priority
PVC-based QoS assigns different levels of priority, or precedence, to different permanent virtual circuits. This is
useful when you have, for example, one PVC set up for traditional Internet services (Web browsing, e-mail, and
the like) and another PVC set up to carry time-sensitive data such as VoIP or IPTV streams. Giving the second PVC
a higher QoS level helps ensure the best possible voice or picture quality.
