Hi there. I have issue with MX84 (firmware MX 15.42.1) and local DNS server. My network configuration has 3 VLANs

I don't use DHCP in my VLAN 3 (static IP assignment)

My DNS server (Windows Server 2012R2 with Active Directory) is located in VLAN1. When I try to resolve from VLAN 3 any DNS record that my DNS server holds, I see reply from public DNS.

I can ping server in different VLAN or reach it with tracert, but only by IP, so it's not a routing issue. Here is my interface configuration

In same VLAN where my DNS server is located, there is no issue with DNS resolving.
What settings must I change for using my local DNS server in all VLANs?
