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 posses ses lowe r QoS t raffic than De fault cl ass ( all othe r

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 packet s have port number

80 is high priority and will have higher precedence to be sent out from port 1.
