DNS location doesn’t change when AdGuard VPN is in integrated mode combined with AdGuard for iOS

Open ghost opened this issue 1 year ago • 4 comments

When AdGuard VPN is connected in integrated mode with AdGuard Ad Blocker using DNS protection (with AdGuard DNS), the DNS location closest to the user is used, instead of the DNS location closest to the set VPN location.

When AdGuard VPN is used in general mode using the same AdGuard DNS address, the location closest to the selected VPN server is used.

What should happen is that the DNS location closest to the VPN location should be used.

What is actually happening is that the DNS server location closest to the user is being used, leaking the users location.

Steps to reproduce incorrect behaviour

  1. Set AdGuard Ad Blocker DNS protection to ENABLED
  2. Set DNS server to AdGuard DNS in AdGuard Ad Blocker
  3. Set AdGuard VPN mode to integrated to use AdGuard Ad Blocker's DNS
  4. Set AdGuard VPN location to any location that isn't near your location (in my case, the US)
  5. Browse to https://www.dnsleaktest.com, and IP of VPN location will be shown
  6. Start standard test, and DNS location closest to user will be shown

@jslawler @Bhooty We have reproduced the issue on our side. This behaviour will be improved in the future versions.

Additionally if you suppose set dns server exclusion for a network like I put my network in exclusion since my router is already connected to ag dns

then vpn in integrated uses cloudflare or google instead of the dns selected in adguard app

hope this can be addressed in any way
