So, I'm using expressvpn app on my raspberry pi 4, and sending the connection from the VPN to the ethernet port (I'm going to use it between my ISP modem and my router)
It works well, and if the VPN is disconnected, the internet stops working, as intended. The problem is, it's using the ISP DNS servers instead of the ones supplied by the ExpressVPN app, and I can't find where are the DNS servers being resolved, because theres the expressVPN configurations, the dnsmasq configurations, which I'm pretty sure I've had to set up for sending the connection through the ethernet port and also, mdns from avahi for setting up my raspberrypi.local connection on the LAN
So I'm not sure where are the DNS servers being set up... I tried using nslookup as well, and it says my DNS servers are 127.0.0.1
How can I fix those leaks?
