I Just need some information related to DNS. I have the following scenario.
On my flint router i have openvpn client enabled with vpn policies with domain/ip using not to use VPN.
for example, i have domain youtube.com not to use vpn, so how dns will be resolved in that case, will it resolve the vpn’s local regional IP addresses or as it is bypass it will resolve outside of VPN ?
Note: DNS servers which i’m actually using are actually routed over vpn, as i have never mentioned to be bypass
ipleak will help you determine what DNS is being used when you’re enforcing other devices (‘clients’) to use/not use the VPN, accordingly.
IDK how much of this will work w/ AdGuard Home & I doubt it without some unsupported customizations; by default that takes control of all DNS resolution at the local level/local connections within OpenWrt & forwards them to the AdGuard Home service which runs independently ‘behind the scenes’ of the GL GUI which runs atop OpenWrt Linux.
Your Flint would be sending all DNS fowards to something like 127.0.0.1#5453 to shunt that DNS lookup through AdGuard Home first. I don’t use AdGuard so I can’t confirm/comment further.
Port 5453 isn’t a standard DNS port. :53 is the classic, unencrypted, insecure port (Do53).
