4.4.4 ADVANCED - IP QoS
IP QoS:
IP Quality of Service (QoS) prioritize data streams to ensure that basic connectivity is maintained
when running multiple services over one connection.
For example, if you are using a peer-to-peer file-sharing program at the same time as performing normal web
browsing, you can configure QoS to limit the resources dedicated to the peer-to-peer session in order to
ensure web browser connectivity.
Leave it at its default setting if you do not know the QoS.

4.4.5 ADVANCED - Port Forwarding
Port Forwarding:
Port Forwarding is necessary because NAT ( Network Address Translation ) only forwards
traffic from the Internet to the LAN if a specific port mapping exists in the NAT translation table. Because of
this, the NAT provides a level of protection for computers that are connected to your LAN. However, this also
creates a connectivity problem when you want to make LAN resources available to Internet clients, which you
may want to do to play network games or host network applications.
Thus Port Forwarding is necessary to run certain games, chat clients, video-conferencing and other kinds of
application. You might also need to configure port forwarding if you intend to host a web server or mail server
that is to be visible outside your LAN.

The following screen will pop-up after clicking the DMZ button. Place a check to enable the DMZ
functionality. Select the
WAN Connection
