This maps e-mail traffic coming from port 25 to the highest priority, which you have created in the

address to the E-mail queue (see the Source fields).

Verify that the queue setup works by checking Network Settings > QoS > Monitor. This shows
the bandwidth allotted to e-mail traffic compared to other network traffic.
4.9 Access the VDSL Router Using DDNS
If you connect your VDSL Router to the Internet and it uses a dynamic WAN IP address, it is
inconvenient for you to manage the device from the Internet. The VDSL Router’s WAN IP address
changes dynamically. Dynamic DNS (DDNS) allows you to access the VDSL Router using a domain
name.
To use this feature, you have to apply for DDNS service at www.dyndns.org.
This tutorial covers:
• Registering a DDNS Account on www.dyndns.org
• Configuring DDNS on Your VDSL Router
• Testing the DDNS Setting
Note: If you have a private WAN IP address, then you cannot use DDNS.
Class Name Give a class name to this traffic, such as E-mail in this example.
From Interface This is the interface from which the traffic will be coming from. Select LAN1
for this example.
Ether Type Select IP to identify the traffic source by its IP address or MAC address.
IP Address Type the IP address of your computer - 192.168.1.23. Type the IP Subnet
Mask if you know it.
MAC Address Type the MAC address of your computer - AA:FF:AA:FF:AA:FF. Type the
MAC Mask if you know it.
To Queue Index Link this to an item in the Network Settings > QoS > Queue Setup
screen, which is the E-mail queue created in this example.
