DMZ
A Demilitarized Zone (DMZ) is an isolated area in your local network where
private IP addresses are mapped to specified internet IP addresses, allowing
unrestricted access to the private IP addresses but not to the wider local
network.
You can define a virtual DMZ host here. This is useful for example, if a
network client PC cannot run an application properly from behind an NAT
firewall, since it opens the client up to unrestricted two
‐
way access.

7. QoS
Quality of Service (QoS) is a feature to manage
Internet bandwidth efficiently. Some applications
require more bandwidth than others to function
properly, and QoS allows you to ensure that sufficient bandwidth is available.
Minimum or maximum bandwidth can be guaranteed for a specified
application.
QoS can improve the BR
‐
6228nS V2/nC V2’s performance. QoS is
recommended to optimize performance for online gaming.
