Click Apply. The Routing screen should display the route you just added.

Now B should be able to receive traffic from A. You may need to additionally configure B’s firewall 
settings to allow specific traffic to pass through.

This section contains tutorials on how you can configure the QoS screen.

Note: Voice traffic will not be affected by the user-defined QoS settings on the ADSL 

Device. It always gets the highest priority.

This example assumes that you want to prioritize e-mail traffic because you have to send important 
mails and urgent updates to clients very often.

In the following figure, your Internet connection has an upstream transmission bandwidth of 1000 
kbps. For this example, you want to configure QoS so that e-mail traffic gets the highest priority 
with at least 500 kbps. You can do the following:

• Configure a queue to assign the highest priority queue (7) to e-mail traffic sent from the LAN 

interface, so that e-mail traffic would not get delayed when there is network congestion. 

• Note the IP address (192.168.1.23 for example) and/or MAC address (AA:FF:AA:FF:AA:FF for 

example) of your computer and map them to queue 7.
