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.
