problem prioritizing internet connections while using a vpn

[TEGNO]

So I was trying to use two network connections at the same time. one of them is my regular ethernet connection and the other is my phone tethered to my pc. the problem was that i wanted to switch between them automatically so that as soon as I tether my phone, my pc switches to the tethered connection automatically without the need to disconnect and reconnect to my ethernet connection. I HAVE FOUND THE SOLOUTION TO THAT PART by prioritizing my connections and giving them different metric.

My main issue is that my problem still persists when i connect to my vpn. in this case Windscribe. When i connect to windscibe the connection automatically goes through my ethernet. and i dont want that to happen. i want to connect to my tethered connection. What should i do?

***NOTE***

1. i tested basically the same thing on another computer. same Winscribe version and the same setup. even the same internet providers. and that's why i don't think it's software related.

2. the pc i'm using has 2 lan sockets going into the motherboard and as far as i know it's the only difference between this pc and the other one which was ok so that's why i'm posting it here.

 

Any other questions?

Thanks for the answers
