Your question, as best as I could tell, is that you want DNS traffic to exist through your VPS node, rather than your client machine.

I posited one reason this could be happening, and additionally, a similar setup that provably routes traffic through the VPN based on the method I described.

Nobody in here is obligated to help you, I gave you a couple threads to pull on to resolve your question, so maybe consider accepting it graciously, rather than being obstinate.
