There is a computer in lab I need to turn it on wakeonlan, I followed these instructions. I used gWakeOnLan tool to wake up the system. The default UDP port number is 9 and i checked from the website that port is blocked in my network. so i thought any other will work which are open in my network but nothing worked for me I tried 80, 443, 22, 23,20, 14000

You have to forward the external port to your internal network. You are most likely under a firewall/router that blocks incoming external connections.
