Thank you for suggestions. First app wants root. And already using Netguard as a firewall for long time. I did suspect there should be a way to fool the stock tethering service with it but couldn’t figure it out. Can you guide me on how to implement it for the purpose in subject please?
Netguard is a great app, but some settings are not clear to me, I simply don’t understand what is subnet routing and allow lan access and what they do?
