Flint GL-AX1800: after 4.8.3 upgrade, requests through VPN tunnel don't use AGH

Hello,

I have just upgraded my Flint GL-AX1800 from 4.7 to 4.8.3 (latest stable) and now, when VPN tunnel is on, the requests don't go through Adguard Home anymore (requests don't appear in AGH query logs and filtering rules don't apply).

I am using VPN in policy mode, only one tunnel (from LAN and Wireguard Server to all targets). If VPN tunnel is on, in AGH I only see requests from Guest network. If I turn off tunnel, AGH see all my requests.

Can you help me having my VPN requests go through AGH again ?

Hi,

We conducted local testing using the AX1800 v4.8.3, but were unable to reproduce the issue. VPN and AdGuard Home are working properly.

Below are screenshots of our test configuration:

VPN - VPN Dashboard:

Network - DNS:
(Enable “Allow Custom DNS to Override VPN DNS” so that AdGuard Home can override the VPN’s DNS)

Application - AdGuard Home:

Test results:
The AdGuard Home logs show DNS requests from LAN devices:

You may want to refer to our test configuration and try again.
If the issue persists, you may try resetting the device to factory settings to rule out any leftover configurations from previous upgrades interfering with the functionality if choosing the Keep Configuration when upgrading.

That's indeed the option “Allow Custom DNS to Override VPN DNS” that was missing. With the message in the banner, I thought all these options were irrelevant with AGH enabled.
It works now.
Thank you !
