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.

DMZ:

A DMZ ( Demilitarized Zone ) is added between a protected network and an external

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

functionality. Select the
