This maps e-mail traffic coming from port 25 to the highest priority, which you
have created in the previous screen (see the IP Protocol field). This also maps
your computer’s IP address and MAC address to the E-mail queue (see the
Source fields).
4 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 ZyXEL Device Using DDNS
If you connect your ZyXEL Device to the Internet and it uses a dynamic WAN IP
address, it is inconvenient for you to manage the device from the Internet. The
ZyXEL Device’s WAN IP address changes dynamically. Dynamic DNS (DDNS)
allows you to access the ZyXEL Device 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
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.
