button. We can find Special TCP/UDP port 80, 280,
443, 25, 110, 20, 21, 69, 119, 2009 have already existed and defined for your
using but it is fine that you modify this pre-defined TCP/UDP port with other
port number you prefer. In ” Down prioritize web browsing, e-mail, FTP and
news “ L4 QoS Configuration with default setting, special defined TCP/UDP
port possesses lower QoS traffic than Default class ( all other TCP/UDP ports
such as port 81,82,83,84,85, etc.). Giving an example, when we transmit TCP
packets with port number 80 at each of port 2 and port number 81 at port 3 to
port 1 until the congestion happens. The packets from port 3 will be dropped
by port 1 because the TCP packets have port number 80 is high priority and
will have higher precedence to be sent out from port 1.
