How to enable Wake on Lan

Good afternoon,

I have installed the Wake on Lan by Solarwinds  application on two computers,one using Windows 10 Pro and the other Windows 10 Enterprise. However,despite configuring the two routers,editing changes in Firewall on both computers,as well as enabling Wake on Lan on the computer I would like to connect to ( the one using Windows 10 Enterprise),I am still unable to wake up the computer using Windows 10 Enterprise.
 
Is it possible to provide me the complete steps on what needs to be done to wake up a computer please?
 
I have set both internal and external ports as number 9;is that good?
 
Thanks and kind regards,
